A change in erection quality may be your body’s way of asking for attention. Diabetes, high blood pressure, obesity, heart disease, poor sleep, stress, and medication side effects can all contribute to erectile dysfunction. Low testosterone may also reduce libido and affect sexual function, but it does not explain every case. The best erectile dysfunction treatment for low testosterone depends on whether hormone deficiency is confirmed and whether other conditions are affecting blood flow or nerve function. A thorough evaluation can help you avoid unnecessary testosterone therapy and focus on care that matches your needs, whether through a local appointment in New Braunfels or eligible virtual care.
Key Takeaways
- Low testosterone and ED are different conditions: Low testosterone may affect libido and spontaneous erections, while ED can also stem from circulation issues, nerve problems, medications, stress, or other health conditions.
- Testing should guide diagnosis: Clinicians may use symptom reviews, two morning testosterone tests, medication assessments, and screenings for diabetes, cardiovascular risks, thyroid concerns, sleep apnea, and prostate health.
- Treatment should match the cause: Options may include lifestyle changes, PDE5 inhibitors, testosterone therapy for confirmed deficiency, counseling, vacuum devices, or urology care, with follow-up to monitor results and safety.
How Are Low Testosterone and Erectile Dysfunction Connected?
Low testosterone and erectile dysfunction (ED) can happen at the same time, but they are separate conditions. Testosterone influences sexual desire, arousal, and some of the nerve and blood vessel activity involved in an erection. When testosterone levels are consistently low, a person may notice less interest in sex, fewer spontaneous or morning erections, or difficulty responding to sexual stimulation.
An erection requires more than adequate testosterone. The brain, nerves, blood vessels, penile tissue, and psychological state all play a role. Health conditions such as diabetes, high blood pressure, obesity, and heart disease can affect circulation, while certain medications, stress, depression, and relationship concerns can affect arousal or performance.
This overlap can make the cause difficult to identify without an evaluation. A clinician may recommend hormone testing, an ED assessment, a medication review, or screening for cardiovascular and metabolic concerns. Treatment depends on the underlying cause. Some people benefit from testosterone replacement therapy (TRT), an ED medication, lifestyle changes, or a combination of approaches. Others may have normal testosterone and need treatment directed at blood flow, nerve function, mental health, or another condition.
How testosterone affects sexual desire and arousal
Testosterone helps regulate libido, or sexual desire, through its effects on areas of the brain involved in sexual interest. It also supports nerve signals that travel through the spinal cord and contribute to erectile function. Research on testosterone and erectile physiology describes the hormone’s role in both central libido pathways and the signals involved in erections.
When testosterone is below the expected range, some people experience fewer sexual thoughts, reduced interest in sex, or less response to stimulation. Low testosterone does not affect everyone in the same way, however. Stress, poor sleep, depression, medication side effects, and chronic illness can also reduce desire. A blood test and symptom review are needed before considering testosterone treatment.
How nitric oxide and blood flow affect erection firmness
Sexual stimulation causes nerves to release chemical signals, including nitric oxide, in penile tissue. Nitric oxide helps relax smooth muscle in the penis, allowing blood to enter the erectile chambers. As the tissue expands, it compresses veins that would otherwise carry blood away, helping the erection remain firm.
Testosterone may support this process partly through effects on the endothelium, the thin lining inside blood vessels. However, the relationship is complex. High blood pressure, diabetes, plaque buildup in the arteries, smoking, and other circulation problems can interfere with the same process. Research on testosterone’s role in erectile function describes both endothelial and non-endothelial pathways that may contribute to erectile changes.
Why low testosterone is only one possible ED cause
Low testosterone can reduce sexual desire and may affect the hormonal environment that supports erections. Still, ED is often related to vascular or neurological factors rather than hormones alone. Nerve damage, reduced blood flow, pelvic surgery, prostate conditions, medication side effects, anxiety, depression, and relationship stress can all affect erectile function.
Some people have low testosterone and ED at the same time. Others have ED despite having testosterone levels within the expected range. This distinction matters because TRT is intended for people with confirmed hypogonadism, not as a general treatment for every erection problem. The American Urological Association’s ED guideline-guideline) recommends evaluating contributing medical and psychological factors rather than assuming one cause.
How ED can signal vascular or metabolic health concerns
The arteries supplying the penis are relatively small, so circulation changes may affect erectile function before other cardiovascular symptoms appear. ED can be associated with high blood pressure, high cholesterol, obesity, insulin resistance, type 2 diabetes, and heart disease. It does not prove that someone has a heart condition, but it can be a reason to review cardiovascular risk factors with a clinician.
Low testosterone is also linked with several of these conditions, which can make the connection difficult to sort out. As WebMD explains, low testosterone and ED may share underlying health factors, including obesity, type 2 diabetes, and cardiovascular disease. Persistent or worsening ED deserves medical attention, especially when it develops suddenly or occurs with chest discomfort, shortness of breath, fainting, or reduced exercise tolerance.
Which Low Testosterone Symptoms Can Contribute to ED?
Low testosterone may affect sexual function, but it is rarely the only possible explanation for erectile dysfunction (ED). Testosterone influences sexual desire, arousal, muscle mass, energy, mood, and overall well-being. At the same time, erections depend heavily on healthy blood vessels, nerve function, and psychological comfort.
A change in erections may also point to diabetes, high blood pressure, cardiovascular disease, medication side effects, poor sleep, depression, anxiety, or relationship stress. These conditions can occur alongside low testosterone, so treating one issue may not resolve every symptom.
Pay attention to patterns rather than a single symptom. A gradual decline in libido combined with fewer morning erections, persistent fatigue, and changes in muscle mass may justify a hormone evaluation. However, symptoms alone cannot confirm testosterone deficiency. A clinician must review your health history and use properly timed blood tests to determine whether low testosterone is present and whether it may be contributing to ED.
Recognizing low libido, fewer morning erections, and erection changes
A noticeable decline in sexual desire can be one of the more recognizable symptoms associated with low testosterone. You may feel less interested in sex, need more stimulation to become aroused, or notice less frequent spontaneous or morning erections. Some men also report changes in erection firmness or difficulty maintaining an erection during sexual activity.
Low testosterone may reduce libido and affect the hormonal environment that supports sexual function. However, sexual desire and erection quality are separate concerns. You can have a normal sex drive and still develop ED because of reduced blood flow, nerve problems, medication effects, anxiety, or another health condition.
You can read more about how low testosterone and ED may be connected, including why the conditions do not always occur together. Share any changes in libido or morning erections with your clinician, especially if they continue for several weeks or occur with other symptoms.
Identifying fatigue, muscle loss, increased body fat, and reduced endurance
Low testosterone can cause symptoms that do not seem directly related to sexual health. These may include persistent fatigue, reduced exercise endurance, loss of muscle mass, or an increase in body fat. The changes may develop gradually, so it can be difficult to tell whether they reflect hormone changes, stress, aging, reduced activity, or another health issue.
Body composition can also affect erectile function indirectly. Increased visceral fat and reduced muscle mass are associated with inflammation and insulin resistance, which may impair blood vessel health. Since erections require adequate blood flow, these changes can contribute to ED.
Fatigue and changes in body composition have many possible causes, including poor sleep, sleep apnea, thyroid disorders, depression, diabetes, and certain medications. A clinician may assess these possibilities alongside testosterone rather than assuming that one hormone explains every symptom. Keeping notes about your energy, exercise tolerance, weight, and sexual symptoms can make the appointment more productive.
Noticing mood, sleep, concentration, and temperature changes
Testosterone supports more than libido and erections. Some men with low levels report low mood, irritability, reduced motivation, difficulty concentrating, or a general loss of well-being. Sleep changes may also occur, although poor sleep itself can affect energy, hormone regulation, and sexual performance.
Some people report feeling unusually warm or experiencing changes in sweating, but temperature symptoms are not specific to low testosterone. Thyroid conditions, infections, medication effects, anxiety, and other health concerns can cause similar changes. For that reason, these symptoms should be considered as part of a larger pattern.
Untreated sleep apnea deserves particular attention. It can contribute to daytime fatigue, mood changes, reduced sexual function, and ED. Mental health concerns can also affect arousal and sexual confidence. Testosterone’s role in sexual function and overall well-being is important, but it is only one part of a complete evaluation.
Why symptoms alone cannot confirm hypogonadism
Hypogonadism means the body is not producing enough testosterone for its needs. Several symptoms may suggest it, but no symptom confirms the diagnosis on its own. Some men with low testosterone have normal erections, while many men with normal testosterone levels experience significant ED.
Stress, cardiovascular disease, diabetes, medication effects, depression, anxiety, relationship concerns, and performance anxiety can all cause changes that resemble testosterone deficiency. Low testosterone can also occur alongside these conditions, which means more than one factor may need attention.
Clinicians generally diagnose testosterone deficiency by combining compatible symptoms with consistently low blood levels. Testosterone levels change throughout the day, so testing is usually performed in the morning and repeated on a separate day when the initial result is low. The Endocrine Society’s clinical guidance on testosterone deficiency explains why accurate testing and appropriate follow-up matter.
A clinician may also order additional tests to assess related hormones, general health, and possible causes. This process helps determine whether testosterone is contributing to ED and whether another condition requires treatment first.
How Do Clinicians Diagnose Low Testosterone and Erectile Dysfunction?
Low testosterone and erectile dysfunction can occur together, but one does not automatically cause the other. ED may be related to reduced blood flow, diabetes, medication effects, stress, relationship concerns, or several factors at once. Low testosterone also requires more than one abnormal lab result. Clinicians look for consistent symptoms, confirm hormone levels, and investigate other conditions that may affect sexual function.
Your evaluation may happen through a virtual visit, an in-person appointment, or a combination of both. A clinician may review your symptoms remotely, then arrange local lab work or an in-person examination when needed. The American Urological Association’s testosterone deficiency guideline emphasizes the importance of matching symptoms with accurate laboratory testing.
A careful evaluation can also identify health concerns that deserve treatment, whether or not low testosterone is confirmed. Be open about changes in sexual function, sleep, mood, energy, and overall health. These details help your clinician recommend care that addresses the likely cause rather than focusing on one test result.
Reviewing sexual, medical, medication, and mental health history
Your clinician will usually ask about erections, libido, orgasm, ejaculation, and morning erections. Be ready to describe when the changes began, whether they happen every time, and whether you can get or maintain an erection during masturbation or sexual activity. These details can help distinguish physical, hormonal, and situational factors.
Your medical history may include diabetes, high blood pressure, high cholesterol, heart disease, obesity, sleep problems, injuries, and prior pelvic or prostate procedures. Your clinician may also review prescription medications, over-the-counter products, recreational substances, and supplements. Some of these can affect testosterone, desire, or erectile function.
Mental health and relationship factors matter, too. Anxiety, depression, chronic stress, and relationship strain can affect erections even when hormone levels are normal. NYU Langone Health’s ED evaluation guidance describes a detailed health and sexual history as an important part of the diagnostic process.
Examining blood pressure, cardiovascular health, and genital health
An in-person examination may include blood pressure, heart rate, weight, waist measurement, and other signs of cardiovascular or metabolic health. Blood vessels play a central role in erections, so ED can sometimes appear before other symptoms of vascular disease. Your clinician may ask about chest discomfort, shortness of breath, exercise tolerance, and family history of heart conditions.
The genital examination may assess the penis, testicles, and surrounding tissues. Clinicians may look for testicular shrinkage, differences in testicle size, penile curvature, plaques, or other findings that could affect sexual function or hormone production. They may also assess body hair, breast tissue, and muscle development when looking for signs associated with hormone changes.
The examination does not identify every cause of ED by itself. It adds context to your symptoms, medical history, and lab results. Patient evaluation guidance from the Center for Male Reproductive Medicine and Microsurgery outlines the role of physical and cardiovascular assessment in an ED workup.
Confirming low testosterone with two separate morning tests
Testosterone levels change throughout the day and are often highest in the morning. For that reason, clinicians commonly order a total testosterone test in the early morning, often between 7 and 10 a.m. If the result is low, they generally repeat the test on a different morning before diagnosing testosterone deficiency.
The second test matters because illness, poor sleep, intense exercise, calorie restriction, and certain medications can temporarily lower testosterone. Testing methods and laboratory reference ranges can also vary. A diagnosis typically requires consistent symptoms and repeatedly low results, not a single borderline reading.
Your clinician may give you instructions about fasting, medication timing, and when to complete testing. Do not stop a prescribed medication unless your clinician tells you to. The Endocrine Society’s testosterone therapy guideline recommends confirming low testosterone with accurate morning measurements and repeating the test when the initial result is low.
Using free testosterone and SHBG for borderline results
Total testosterone measures testosterone circulating in the blood, including the amount attached to proteins and the smaller amount that remains unbound. Free testosterone refers to the unbound portion. In some people, total testosterone may appear normal or borderline while the available amount does not match the clinical picture.
Sex hormone-binding globulin, or SHBG, affects how much testosterone is available to tissues. Age, obesity, thyroid conditions, liver disease, and some medications can change SHBG levels. When total testosterone falls near the lower end of the laboratory range, a clinician may order SHBG and calculate or measure free testosterone.
These tests do not replace the overall evaluation. Results need to be interpreted alongside symptoms, the testing method, and the laboratory’s reference range. A clinician may repeat testing if the results do not fit your symptoms. The AUA testosterone deficiency guideline discusses the role of free testosterone when total testosterone results are unclear.
Testing LH, FSH, prolactin, and TSH to identify underlying causes
Once low testosterone is confirmed, additional hormone tests can help identify where the problem may originate. Luteinizing hormone, or LH, and follicle-stimulating hormone, or FSH, provide information about communication between the brain, pituitary gland, and testicles. The results may help distinguish a testicular cause from a problem involving the pituitary gland or hypothalamus.
A prolactin test may be appropriate when testosterone is low and LH is low or low-normal. It may be especially useful when symptoms include headaches, vision changes, breast discharge, or other concerning changes. Elevated prolactin can interfere with reproductive hormone signaling and sexual function.
Thyroid-stimulating hormone, or TSH, may also be checked because thyroid disorders can affect energy, mood, libido, and erections. These tests are not necessary for every patient. Your clinician will choose them based on your history and initial results. Abnormal findings may lead to repeat testing, additional evaluation, or a referral to an endocrinologist.
Checking A1C, glucose, lipids, CBC, PSA, and other targeted markers
ED can be an early sign of diabetes or cardiovascular risk, so clinicians may check blood glucose or hemoglobin A1C. A1C estimates average blood sugar over several months. A lipid panel measures cholesterol and triglycerides, which can help identify factors that affect blood vessel health.
A complete blood count, or CBC, may provide a baseline before testosterone treatment and help identify conditions such as anemia. If testosterone therapy is being considered, clinicians may pay particular attention to hematocrit, the percentage of blood made up of red blood cells, because treatment can increase it.
A prostate-specific antigen, or PSA, test may be recommended based on age, risk factors, symptoms, and shared decision-making. It is not a universal test for every patient. Other tests may be ordered when your history suggests a specific concern. The AUA’s erectile dysfunction guideline-guideline) supports evaluating patients with ED for medical conditions that may contribute to sexual dysfunction.
Screening for sleep apnea and medication-related effects
Poor sleep can affect testosterone, energy, mood, and erections. Your clinician may ask whether you snore loudly, wake up gasping, experience morning headaches, or feel excessively sleepy during the day. These symptoms can suggest obstructive sleep apnea, which may require a sleep evaluation.
Medication review is another practical part of the workup. Some blood pressure medicines, antidepressants, opioid pain medicines, corticosteroids, and other drugs may affect libido, erections, or hormone levels. Recreational substances and high-dose supplements may also contribute.
Do not stop or change a medication on your own. Ask whether a dose adjustment, alternative medication, or separate treatment could help. Treating sleep apnea or addressing a medication effect may improve symptoms without testosterone therapy. NYU Langone’s ED diagnosis guidance includes medication effects and other health conditions among the factors clinicians consider.
Discussing fertility plans before choosing treatment
Tell your clinician if you may want to have biological children now or in the future. Testosterone replacement therapy can reduce the signals that stimulate sperm production, which may lower sperm counts or cause temporary infertility. It should not be started without discussing this potential effect.
If fertility is a priority, your clinician may consider other approaches, such as treating an underlying condition or referring you to a reproductive urologist or endocrinologist. A semen analysis may be useful in some situations, especially when conception is a current goal.
Fertility planning applies even if pregnancy is not an immediate concern. Treatment choices can affect sperm production for as long as therapy continues, and recovery may take time after stopping. Ask about available options, expected monitoring, and whether fertility preservation should be considered. The American Society for Reproductive Medicine’s male infertility resources offer additional information about testosterone treatment and fertility.
Which Erectile Dysfunction Treatments Help When Testosterone Is Low?
The right treatment depends on whether low testosterone is confirmed, how strongly it contributes to your symptoms, and whether another health issue is affecting erections. Low testosterone may reduce sexual desire and make erections more difficult, but it is only one possible cause. Diabetes, high blood pressure, medication side effects, anxiety, sleep apnea, obesity, and blood vessel disease can also contribute to erectile dysfunction.
Treatment should begin with an evaluation rather than a single prescription. A clinician may repeat early-morning testosterone testing, review your symptoms and medications, and assess cardiovascular health, prostate health, and fertility plans. This process helps identify the likely cause and reduces the chance of using testosterone when it is unlikely to help.
If you receive treatment, follow-up is important. Your clinician may monitor testosterone levels, blood pressure, hematocrit, symptoms, and prostate health. They can then adjust the plan based on your response and any side effects.
Treating confirmed hypogonadism with testosterone replacement therapy
Testosterone replacement therapy, or TRT, may help men with confirmed hypogonadism, particularly when low testosterone occurs alongside low sexual desire, fewer spontaneous erections, fatigue, or other related symptoms. TRT may improve libido and, for some patients, erectile function. However, symptoms alone do not confirm hypogonadism. Diagnosis generally requires compatible symptoms and consistently low testosterone levels on properly timed blood tests.
Before treatment, a clinician should review the potential benefits and risks. TRT may affect fertility, red blood cell levels, sleep apnea, acne, mood, and prostate monitoring. The Endocrine Society’s testosterone therapy guidance explains who may be considered for treatment and which safety checks may be needed.
TRT also requires ongoing follow-up. Your clinician may monitor testosterone, hematocrit, blood pressure, symptoms, and prostate health. If the treatment does not help or creates concerning side effects, they can adjust or discontinue it safely.
Choosing among TRT gels, injections, patches, and pellets
TRT is available in several forms, including injections, skin gels, patches, nasal preparations, oral medications, and long-acting pellets. Injections may be given every few weeks, depending on the medication and dose. Gels are applied regularly to the skin, while patches deliver testosterone through the skin. Pellets are placed beneath the skin by a trained clinician and release testosterone gradually.
Each option has practical considerations. Gel can transfer to another person through skin contact if it is not applied and covered correctly. Injections may cause changing testosterone levels or symptoms between doses. Patches can irritate the skin, and pellets require a minor procedure for placement. WebMD’s overview of testosterone replacement options describes these delivery methods in more detail.
Your choice may depend on cost, convenience, insurance coverage, needle preferences, treatment goals, and how your body responds. Do not change the dose or delivery method without medical guidance.
Using sildenafil, tadalafil, and other PDE5 inhibitors
PDE5 inhibitors are common treatments for erectile dysfunction. This group includes sildenafil, tadalafil, vardenafil, and avanafil. These medications improve blood flow to the penis during sexual stimulation, helping many men achieve and maintain an erection. They do not create sexual desire automatically and do not treat low testosterone itself.
Sildenafil and vardenafil generally work for several hours, while tadalafil may last longer and may be prescribed for daily or as-needed use. Timing, food intake, dose, and sexual stimulation can affect the result. A clinician may adjust the prescription after reviewing your response and side effects.
PDE5 inhibitors are not appropriate for everyone. Possible side effects include headache, flushing, nasal congestion, indigestion, dizziness, and vision changes. These medications must not be combined with nitrate medications. Certain combinations with alpha blockers or other drugs also require careful review. The European Association of Urology guidance on erectile dysfunction treatment provides additional clinical information.
Combining TRT and PDE5 treatment when appropriate
Some men with confirmed hypogonadism continue to experience ED after starting TRT. In that situation, a PDE5 inhibitor may provide additional support. Testosterone may address hormone-related changes in desire and sexual function, while a PDE5 inhibitor supports the blood flow needed for an erection. A clinician may recommend both treatments when the combination is safe and appropriate.
Combination treatment is not automatically better for every patient. Your clinician may treat confirmed low testosterone first, assess your response, and then add a PDE5 inhibitor if erection problems continue. In other cases, a PDE5 inhibitor may be prescribed first, especially when ED is the primary concern.
Research summarized in the European Association of Urology recommendations suggests that some men with hypogonadism who do not respond adequately to PDE5 inhibitors may respond better after starting testosterone treatment. The decision should account for heart health, current medications, fertility plans, and treatment goals.
Understanding why TRT may not resolve ED alone
TRT may improve erections when low testosterone is a meaningful cause of the problem, but it cannot correct every condition that affects sexual function. ED often has several contributors, including narrowed blood vessels, diabetes, high blood pressure, obesity, nerve damage, medication effects, depression, anxiety, and relationship stress.
Some men notice improved sexual desire before they notice firmer erections. Others have normal desire but continue to have difficulty getting or keeping an erection. In these cases, a PDE5 inhibitor, counseling, lifestyle changes, or treatment for another health condition may be helpful.
If ED does not improve, your clinician may confirm that testosterone reached an appropriate level, review how you use the medication, and reassess other causes. Do not raise the dose on your own. Ask whether you need additional testing or a referral to a urologist.
Avoiding TRT when testosterone levels remain normal
If testing shows that your testosterone level is consistently within the expected range, TRT is unlikely to improve ED and may expose you to unnecessary risks. Raising testosterone above a healthy range does not address many common causes of erection problems, including impaired blood flow, medication effects, anxiety, or diabetes.
A single test may not be enough to confirm low testosterone. Levels change throughout the day, and illness, poor sleep, certain medications, and testing conditions can affect the result. Clinicians commonly confirm a low result with a second early-morning test. They may also check free testosterone when total testosterone is near the lower limit.
Treatment should match the cause. If testosterone is normal, your clinician may focus on PDE5 inhibitors, cardiovascular risk factors, sleep, mental health, medication changes, or another ED treatment. The WebMD explanation of low testosterone and ED also notes that TRT generally will not help ED when testosterone levels are normal.
Avoiding testosterone boosters and unregulated products
Over-the-counter testosterone boosters, online hormone products, and supplements marketed for sexual performance are not reliable substitutes for medical evaluation. Their ingredients and doses may vary, and some products may contain undeclared prescription drugs or hormone-like substances. They may interact with medications or delay care for an underlying condition.
Do not start TRT obtained from an unverified source, even if the product promises rapid results. Prescription testosterone requires a diagnosis, appropriate dosing, and follow-up testing. A clinician should also review fertility plans because TRT can reduce sperm production and may not be suitable for someone trying to conceive.
Before using any supplement, bring the label or ingredient list to your healthcare professional. The FDA’s information on tainted sexual enhancement products explains why products marketed for sexual performance deserve caution. Choose treatments with known ingredients, clear dosing instructions, and professional monitoring.
Which Other Evidence-Based ED Treatments Can Help?
Testosterone replacement therapy and PDE5 inhibitors are not the only treatments for erectile dysfunction. The best option depends on the cause of ED, your overall health, your preferences, and how you responded to previous treatments. Some therapies improve blood flow directly, while others address anxiety, relationship stress, or physical changes that interfere with erections.
A clinician can help you compare these options and choose an approach that fits your needs. The National Institute of Diabetes and Digestive and Kidney Diseases explains several established ED treatments, including vacuum devices, alprostadil, counseling, and penile implants.
ED can also have more than one cause. For example, low testosterone may affect libido while diabetes, medication side effects, or vascular disease affects blood flow. Treating only one factor may not fully resolve erection problems. Be open with your clinician about your symptoms, medications, sexual concerns, and treatment goals so you can build a complete plan.
Using vacuum erection devices
A vacuum erection device, also called a penis pump, uses gentle suction to draw blood into the penis. After an erection develops, an elastic constriction ring placed at the base helps maintain it during sex. VEDs do not require medication, making them an option for people who cannot take PDE5 inhibitors or prefer a non-drug treatment.
A clinician may recommend using a VED alone or with another ED treatment. Follow the device instructions carefully, and do not leave the constriction ring in place longer than directed. Bruising, numbness, or a cool feeling can occur. Ask a clinician before using one if you take blood thinners or have a bleeding disorder, since suction may increase bruising.
Considering alprostadil injections or urethral therapy
Alprostadil increases blood flow to the penis. It may be injected into the side of the penis with a small needle or inserted into the urethra as a small suppository. Both forms can produce an erection without relying on sexual stimulation, but they require proper instruction and dosing.
A clinician should show you how to use alprostadil and explain how long an erection should last. Possible side effects include penile pain, bleeding, dizziness, and scar tissue. Seek emergency care for an erection lasting longer than four hours, as prolonged erections can damage penile tissue. The NIDDK provides additional information about alprostadil treatment.
Choosing penile implants for persistent, treatment-resistant ED
A penile implant may be appropriate when ED continues despite medication, a vacuum device, injections, or other treatments. During surgery, a urologist places either an inflatable or malleable device inside the penis. An inflatable implant uses a concealed pump to create and release an erection. A malleable implant remains firm and can be positioned as needed.
Implants can provide a dependable long-term option, but surgery carries risks, including infection, bleeding, device malfunction, and the possible need for revision. The procedure is generally not reversible, so discuss the benefits, risks, and alternatives with an experienced urologist. An implant does not increase sexual desire or restore sensation, and it does not treat the underlying cause of low libido.
Using counseling, sex therapy, and relationship support
Physical conditions commonly contribute to ED, but anxiety, depression, chronic stress, past sexual experiences, and relationship difficulties can also play a role. Performance anxiety may make it harder to maintain an erection, creating a cycle of worry and frustration. Counseling or sex therapy can help you identify these patterns and develop practical strategies for reducing pressure during intimacy.
A partner can join some sessions if both of you feel comfortable. Therapy does not suggest that ED is imaginary or “all in your head.” It can complement medical treatment by addressing emotional and relationship factors while your clinician evaluates physical causes. Consider working with a licensed mental health professional or certified sex therapist who has experience with sexual health concerns. The American Association of Sexuality Educators, Counselors and Therapists lists certified professionals who provide specialized support.
Seeing a urologist when first-line treatments are insufficient
Ask about a urology referral if ED medicines do not work, cause troublesome side effects, or stop working over time. A urologist can reassess the diagnosis, review your medications and health conditions, and discuss treatments such as injections, urethral therapy, vacuum devices, or penile implants.
Specialized care may be appropriate sooner if ED began suddenly, followed an injury, causes pain or penile curvature, or occurs with urinary symptoms. A clinician may also recommend a urologist when you have complex cardiovascular disease, neurologic symptoms, or treatment needs requiring an in-person examination. Before your visit, prepare a list of medications, supplements, previous treatments, and questions about sexual function.
Which Lifestyle Changes Support ED and Testosterone Treatment?
Lifestyle changes can support care for erectile dysfunction (ED) and low testosterone, but they do not replace a medical evaluation or prescribed treatment. ED may involve circulation, nerve function, hormone levels, medications, mental health, or several factors at the same time. Addressing these areas can improve your overall health and may support sexual function.
Start with changes you can maintain consistently rather than trying to change everything at once. Your clinician can help you set realistic goals, especially if you have heart disease, diabetes, sleep apnea, or another condition that affects exercise, diet, or medication choices.
Combining aerobic activity, resistance training, and weight management
Regular physical activity supports circulation, cardiovascular health, and metabolic function. Try combining moderate aerobic exercise, such as brisk walking, cycling, or swimming, with resistance training using weights, bands, or bodyweight exercises. The CDC’s physical activity guidelines provide general recommendations for building a weekly routine.
If you have been inactive, begin with short sessions and increase gradually. Resistance training can help preserve muscle and support a healthy body composition. Reaching or maintaining a weight that is appropriate for you may also improve blood pressure, blood sugar, and inflammation, all of which can affect sexual function. Exercise has been associated with a lower risk of ED, according to research on physical activity and erectile function. Ask a clinician before strenuous exercise if you have chest pain, significant heart disease, or other concerning symptoms.
Eating a heart-healthy diet with adequate nutrients
The blood vessels involved in erections are affected by many of the same factors that influence cardiovascular health. Build meals around vegetables, fruit, beans, whole grains, nuts, fish, and lean sources of protein. Limiting excess sodium, saturated fat, added sugar, and highly processed foods may support healthier blood pressure and circulation.
You do not need a perfect diet to make progress. Try adding vegetables to one meal, choosing water more often, or replacing processed meats with beans or fish. Adequate nutrition also supports energy and muscle health, which may affect how you feel while receiving testosterone treatment. The National Heart, Lung, and Blood Institute’s heart-healthy eating guidance offers practical examples. If you have diabetes, kidney disease, or dietary restrictions, ask your clinician or a registered dietitian for individualized advice.
Improving sleep and treating sleep apnea
Poor sleep can affect energy, mood, sexual desire, and hormone regulation. Keep a consistent sleep and wake schedule, limit alcohol near bedtime, and reduce screen use before bed. A dark, quiet, comfortable bedroom may also make it easier to get adequate rest.
Loud snoring, gasping during sleep, morning headaches, and persistent daytime fatigue may indicate sleep apnea. Untreated sleep apnea can affect cardiovascular health and may contribute to sexual or hormone-related symptoms. The National Heart, Lung, and Blood Institute’s information on sleep apnea explains common signs and treatment options. Tell your clinician about possible sleep apnea before starting or adjusting testosterone therapy, particularly if you have already received a diagnosis.
Quitting smoking, limiting alcohol, and reviewing substance use
Smoking can damage blood vessels and reduce blood flow, making it harder to achieve or maintain an erection. Quitting can be difficult, but counseling, nicotine replacement, and prescription medications may help. A clinician can recommend a cessation plan based on your health history and nicotine use.
Frequent or heavy alcohol use may affect erections, sleep, mood, and hormone production. Limiting alcohol can support sexual and overall health. Review recreational substances, supplements, and prescription or over-the-counter medications with your care team. Some may affect libido or erection quality, and products marketed as “testosterone boosters” may contain undisclosed or unsafe ingredients. The National Institute of Diabetes and Digestive and Kidney Diseases’ ED treatment guidance discusses lifestyle measures and medical treatment options.
Managing stress and supporting mental and relationship health
Stress, anxiety, depression, and relationship tension can affect desire, arousal, and erection reliability. Concern about sexual performance may also create a cycle in which one difficult experience leads to more anxiety during future sexual activity. This does not mean ED is purely psychological. Physical and emotional factors often occur together.
Consider manageable steps, such as regular movement, brief breathing exercises, time away from work, or an honest conversation with your partner. If low mood, anxiety, or relationship conflict continues, counseling, sex therapy, or mental health care may help. Your clinician can also review whether an antidepressant or another medication is affecting sexual function. Addressing mental health alongside physical causes can support a more complete care plan, as urology guidance on lifestyle and ED explains.
How Can You Use TRT and ED Medications Safely?
Testosterone replacement therapy (TRT) and erectile dysfunction (ED) medications can help when a clinician confirms that they are appropriate for your health needs. They are not interchangeable, though. TRT treats documented testosterone deficiency, while medications such as sildenafil and tadalafil improve blood flow to support an erection. TRT may improve sexual interest, energy, or mood, but it may not correct the blood-flow, nerve, medication, metabolic, or relationship factors that contribute to ED.
Safe treatment starts with accurate testing, a complete medical review, and regular follow-up. The Cleveland Clinic’s overview of TRT explains that treatment may improve symptoms for some men while also causing side effects that require monitoring. Share your full medication and supplement list with your clinician, including heart medications, blood pressure treatments, recreational substances, and over-the-counter products.
It is also important to use these treatments exactly as prescribed. Do not increase your testosterone dose, combine ED medications, or borrow medication from someone else. Contact your care team if symptoms change, side effects develop, or treatment does not improve your sexual function. Some symptoms require urgent attention, including chest pain, sudden shortness of breath, fainting, or an erection lasting longer than four hours.
Reviewing conditions that require TRT caution
TRT may not be appropriate for everyone. Before prescribing it, your clinician should review your history of prostate or breast cancer, urinary symptoms, sleep apnea, heart disease, blood clots, high red blood cell counts, and fertility plans. You may also need a physical examination and laboratory testing to determine whether low testosterone is present and identify its cause.
Do not begin TRT based only on fatigue, low mood, or changes in sexual function. These symptoms can have several explanations, including depression, thyroid disease, medication effects, obesity, poor sleep, and other medical conditions. Your clinician may recommend addressing those factors first or treating them alongside confirmed hypogonadism. The Endocrine Society’s testosterone therapy guideline outlines situations in which treatment should be avoided or delayed.
Managing acne, skin irritation, fluid retention, gynecomastia, and mood changes
TRT can cause acne or oily skin, particularly when testosterone levels rise too high or fluctuate between doses. Gels and patches may cause redness, itching, or irritation where they are applied. Follow the product instructions carefully, wash your hands after applying topical testosterone, and prevent skin-to-skin transfer to children or partners.
Some men develop fluid retention, breast tenderness, or gynecomastia, which is enlargement of breast tissue. Mood changes, irritability, and sleep changes can also occur. Report new or worsening symptoms instead of changing the dose yourself. Your clinician may adjust the dose, change the delivery method, check hormone levels, or look for another cause. The Cleveland Clinic’s TRT guidance lists acne, breast enlargement, worsening sleep apnea, and reduced sperm production among potential side effects.
Monitoring erythrocytosis, blood clots, sleep apnea, and cardiovascular risks
TRT can raise hematocrit, the percentage of blood made up of red blood cells. This condition, called erythrocytosis, may make blood more viscous and increase concern about clotting. A complete blood count before and during treatment helps identify this change. Contact your clinician promptly about severe headaches, unusual flushing, chest pain, sudden shortness of breath, one-sided leg swelling, or sudden neurologic symptoms.
Tell your clinician if you snore loudly, stop breathing during sleep, or feel unusually tired during the day. TRT can worsen untreated sleep apnea in some patients. Your care team should also review blood pressure, cholesterol, diabetes, smoking, and your personal cardiovascular history. A clinical review of TRT adverse effects discusses hematocrit, cardiovascular concerns, sleep apnea, and other risks that may affect your monitoring plan.
Completing prostate evaluations and PSA monitoring
Testosterone can stimulate prostate tissue, so prostate health should be considered before treatment. Depending on your age, symptoms, family history, and other risk factors, your clinician may perform a prostate evaluation and order a prostate-specific antigen (PSA) test before prescribing TRT. Tell your care team about difficulty urinating, blood in the urine or semen, pelvic pain, or a history of prostate abnormalities.
PSA monitoring during treatment can help identify changes that need further evaluation, but it does not replace routine preventive care. A rising PSA does not automatically mean cancer, yet it should not be ignored. Your clinician may repeat the test, assess urinary symptoms, or refer you to a urologist. Guidance on the diagnostic evaluation of ED also emphasizes assessing prostate health when testosterone therapy is being considered.
Considering fertility, sperm production, and family planning
TRT can reduce the hormonal signals that tell the testicles to produce sperm. As a result, sperm counts may fall, sometimes substantially. This matters even if you are not trying to conceive immediately, because fertility may take time to recover after treatment and may not return quickly for everyone.
Tell your clinician about current or future family-planning goals before starting TRT. If you want to preserve fertility, ask about alternatives and whether a referral to a reproductive specialist or urologist would be helpful. Do not rely on over-the-counter “testosterone boosters,” which may contain undisclosed ingredients or inaccurate doses. The Cleveland Clinic explains TRT’s effects on fertility, including its potential to lower sperm production.
Avoiding PDE5 inhibitors with nitrates, riociguat, or interacting medications
PDE5 inhibitors include sildenafil, tadalafil, vardenafil, and avanafil. They can lower blood pressure, so they must not be combined with nitrate medications used for chest pain, such as nitroglycerin or isosorbide. Taking these drugs together can cause a dangerous drop in blood pressure. PDE5 inhibitors should also be avoided with riociguat, a medication used for certain forms of pulmonary hypertension.
Share a complete medication list with your clinician and pharmacist. Some alpha blockers, blood pressure medications, antifungals, HIV medications, and other drugs can change how PDE5 inhibitors work or increase side effects. Never use someone else’s ED medication, combine multiple ED treatments, or take more than prescribed. The FDA’s sildenafil safety information explains important warnings and drug interactions.
Recognizing PDE5 side effects and priapism warning signs
Common PDE5 side effects include headache, facial flushing, nasal congestion, indigestion, dizziness, and changes in vision. Tadalafil may also cause muscle or back pain. These effects are often mild, but severe dizziness, fainting, chest pain, sudden hearing loss, or sudden vision loss requires prompt medical attention.
An erection that lasts longer than four hours, especially when it is painful, is priapism. This is an emergency because delayed treatment can permanently damage erectile tissue. Go to an emergency department rather than waiting for the erection to resolve or taking another medication. Tell emergency clinicians which ED medication you took and when. The NHS guidance on sildenafil side effects describes serious reactions that require urgent care.
Scheduling follow-up for testosterone, hematocrit, PSA, blood pressure, and symptoms
Follow-up appointments help confirm that treatment is working without creating avoidable risks. Your clinician may check testosterone levels according to the product and dosing schedule, along with a complete blood count or hematocrit, blood pressure, PSA when appropriate, urinary symptoms, sleep quality, mood, acne, breast changes, and sexual function. The timing of each test matters, so follow instructions about when to have blood drawn.
Keep a brief record of your dose, injection or application dates, ED medication use, side effects, erections, libido, and any changes in urination or sleep. Contact your clinician if symptoms do not improve, return between doses, or become difficult to manage. If hematocrit becomes too high, your treatment may need to be paused or adjusted. A review of TRT adverse-effect management describes hematocrit monitoring and treatment decisions that may be considered when results become abnormal.
How Can You Access ED and Low Testosterone Care in New Braunfels and Virtually?
If erectile dysfunction or symptoms of low testosterone affect your sex life, energy, or confidence, you have options for seeking care. Patients in New Braunfels may be able to schedule an in-person appointment, while virtual care can provide a convenient starting point for patients in other locations, subject to provider licensure and the services they need.
Care may include a detailed health history, symptom review, physical exam, laboratory testing, and a treatment plan based on your results. Since ED and low testosterone can have multiple causes, a complete evaluation is more useful than requesting a specific medication without understanding what may be contributing to your symptoms.
Learning what a virtual evaluation may cover
A virtual appointment gives you time to discuss changes in erections, sexual desire, energy, mood, sleep, medications, medical conditions, and relationship or mental health concerns. Your clinician may also ask about morning erections, ejaculation, fertility plans, alcohol use, smoking, and treatments you have tried before.
Depending on your symptoms and medical history, your clinician may order blood work through a local laboratory. Testing can help identify conditions associated with ED, including diabetes and hormone abnormalities. NYU Langone Health explains how blood tests can support an erectile dysfunction evaluation, including testing testosterone and other relevant markers.
A virtual visit may also be appropriate for reviewing results, discussing treatment options, and checking your response to care. However, it may not replace an in-person exam when your clinician needs to assess vital signs, perform a physical examination, or provide a service that cannot be completed remotely.
Completing in-person exams, vital checks, or local lab tests when needed
Some patients need an in-person visit before treatment begins or continues. This may include checking blood pressure, weight, heart rate, cardiovascular health, and genital or prostate-related concerns. An exam can also help identify symptoms that may require a referral to a urologist or another specialist.
Your clinician may order tests for glucose or A1C, cholesterol, testosterone, blood counts, prostate-specific antigen when appropriate, and other markers based on your health history. The Center for Male Reproductive Medicine and Microsurgery outlines laboratory testing used in ED evaluations, including glucose testing to help identify diabetes.
If you live in New Braunfels, local care may make it easier to complete an exam, vital checks, and laboratory work as part of one treatment plan. Patients receiving virtual care may be able to use a nearby laboratory, although availability depends on location, provider licensure, and the services required.
Preparing for an ED and low testosterone appointment
Before your appointment, write down when your symptoms began, how often they occur, and whether they have changed. Include details about erection firmness, sexual desire, morning erections, ejaculation, pain, urinary symptoms, sleep, mood, and energy. It may also help to note what seems to improve or worsen your symptoms.
Bring a complete list of prescription medications, over-the-counter products, supplements, and testosterone or sexual health products you have used. Tell your clinician about heart disease, high blood pressure, diabetes, sleep apnea, prostate conditions, past surgeries, and plans to have children. These details can affect which treatments are appropriate.
Ask which tests you need and how the results will guide treatment. Before starting testosterone therapy, your clinician may evaluate prostate health and discuss the potential risks and benefits. The American Academy of Family Physicians describes the evaluation used before testosterone therapy, including the importance of considering previously undiagnosed prostate disease.
Planning follow-up around licensure, service needs, and treatment response
Follow-up plays an important role in ED and low testosterone care. Your clinician may need to review laboratory results, assess your response to treatment, adjust a medication or dose, discuss side effects, or order monitoring tests. Testosterone therapy may require follow-up for testosterone levels, blood counts, PSA when appropriate, blood pressure, symptoms, and overall safety.
The timing and format of follow-up depend on your treatment, location, and clinical needs. Some appointments may take place virtually, while others may require an in-person exam or local laboratory work. Patients receiving care outside Texas should confirm that the clinician is licensed to provide telehealth services in their state.
Tell your clinician if treatment is not helping, your symptoms change, or side effects develop. Research on testosterone replacement therapy emphasizes the importance of weighing potential benefits against adverse effects and monitoring patients throughout treatment.
When Should You Seek Care for ED or Low Testosterone?
Occasional erection changes can happen after stress, poor sleep, alcohol use, or relationship concerns. When symptoms persist, worsen, or affect your confidence and relationships, schedule a medical evaluation. Erectile dysfunction and low testosterone can have several causes, including medication effects, diabetes, cardiovascular disease, sleep disorders, hormone conditions, and mental health concerns.
A clinician can look at the full picture instead of treating erection difficulties or testosterone levels in isolation. As Harvard Health explains, testosterone treatment is not a universal solution for ED, even when testosterone levels are low.
Seeking care for persistent or worsening ED, low libido, or other symptoms
Schedule an appointment if ED continues for several weeks, happens often, or gradually becomes more difficult to manage. You should also seek care for a noticeable drop in sexual desire, fewer morning erections, reduced energy, loss of muscle, changes in body composition, depressed mood, or difficulty concentrating.
These symptoms do not confirm low testosterone on their own. Other health conditions can cause similar changes, and testosterone levels vary throughout the day. A clinician may confirm low testosterone with two separate morning blood tests and order additional testing when appropriate. The American Urological Association’s ED guideline-guideline) recommends evaluating ED as a possible sign of underlying health concerns, not only as a sexual symptom.
Getting urgent help for ED with chest pain, shortness of breath, fainting, or exertional symptoms
Seek emergency care if ED concerns occur with chest pain, chest pressure, shortness of breath, fainting, severe dizziness, or unusual sweating. Get urgent medical attention if sexual activity or physical exertion repeatedly causes chest discomfort or breathlessness. Call 911 when symptoms are severe, sudden, or do not improve with rest.
ED can occur alongside vascular or metabolic conditions, so exertional symptoms should not be handled through an online medication request alone. A clinician may need to assess your heart and circulation before recommending sexual activity or ED medication. The American Family Physician review of ED evaluation describes cardiovascular assessment as an important part of evaluating erectile concerns.
Treating an erection that lasts longer than four hours as an emergency
An erection that lasts longer than four hours, particularly when painful, may be priapism. This is a medical emergency because trapped blood can damage penile tissue and affect future erectile function. Do not wait for it to resolve on its own, and do not rely on exercise, cold showers, or home remedies.
Go to an emergency department or call 911 for immediate guidance. Tell the medical team about any ED medications, testosterone treatment, recreational substances, or other medicines you have used. The National Institute of Diabetes and Digestive and Kidney Diseases explains that ischemic priapism requires prompt treatment to protect erectile function.
Seeking care for sudden sexual changes, severe pain, injury, or neurologic symptoms
Arrange prompt medical care for sudden changes in sexual function, severe testicular or pelvic pain, penile swelling, blood in the urine or semen, or symptoms following an injury. Sudden ED can also occur with numbness, weakness, trouble speaking, vision changes, loss of bladder or bowel control, or numbness around the groin. Call 911 for possible stroke symptoms, severe weakness, or sudden loss of function.
These symptoms may point to an injury, infection, nerve problem, medication reaction, or another condition that needs timely assessment. A clinician can determine whether you need an in-person examination, laboratory testing, imaging, or a urology referral. Virtual care may be appropriate for an initial discussion when the situation is clinically suitable, while urgent or emergency symptoms require immediate in-person evaluation.
Frequently Asked Questions
Can low testosterone cause erectile dysfunction?
Low testosterone may contribute to lower sexual desire, fewer spontaneous erections, and difficulty responding to stimulation. However, ED also depends on blood flow, nerves, medications, mental health, and overall medical conditions. Testing and a full evaluation are needed to determine whether testosterone is contributing.
Will testosterone replacement therapy fix erectile dysfunction?
TRT may help when low testosterone is confirmed and related symptoms are present, especially reduced libido. It may not resolve ED caused by diabetes, vascular disease, medication effects, anxiety, or nerve problems. Some patients may need an ED medication, lifestyle changes, counseling, or another treatment as well.
What tests are used to check for low testosterone and ED?
Clinicians commonly review symptoms, medications, medical history, blood pressure, and cardiovascular risk. Low testosterone is usually confirmed with two separate early-morning blood tests. Additional testing may include free testosterone, SHBG, glucose or A1C, cholesterol, blood counts, thyroid markers, and other hormone tests based on your symptoms.
Are ED medications safe if I have low testosterone?
Medications such as sildenafil and tadalafil may help improve blood flow and erections, but they do not treat testosterone deficiency. They must not be taken with nitrate medications or riociguat, and other drug interactions may require caution. Share your full medication and supplement list with a clinician before using them.
How can I get care for ED or low testosterone in New Braunfels?
Patients in New Braunfels may be able to receive in-person evaluation, examination, laboratory coordination, and follow-up care. Virtual appointments may be available for eligible patients across the country, depending on provider licensure and the services needed. Some concerns still require local lab work, an in-person exam, or referral to a specialist.
