High testosterone in men: symptoms and causes

High testosterone symptoms in men can include acne, breast tissue growth, changes in mood or sex drive, smaller testicles, and fertility problems, especially when testosterone or anabolic steroids are used from outside the body. But symptoms cannot tell you your blood level, and a single high result does not explain its cause. The useful next step is to review the lab result and every medication or supplement with a clinician, who can decide whether to repeat testing or investigate further. High testosterone is not automatically a sign of better health.

Warning signs: when to get medical care

Arrange prompt medical care for a new breast lump or swelling, a testicular lump, or a sudden loss of sex drive with headaches or vision changes. Chest pain during sexual activity needs urgent assessment. An erection lasting more than four hours is an emergency. If low mood comes with thoughts of self-harm, call or text 988 in the United States, or go to an emergency department. New or worsening symptoms deserve medical care, whether or not you suspect testosterone is involved.

What causes testosterone to be high?

For adult men, outside exposure is an important cause to consider. Prescription testosterone, anabolic-androgenic steroids, and products sold as hormone or muscle-building enhancers can raise measured testosterone or expose the body to related androgens. A clinical review describes androgen use for appearance and performance and notes established harms including suppression of the body’s own hormone system, infertility and high red blood cell counts; oral anabolic agents can also affect the liver (Anawalt, 2019, PMID 30753550). Tell your clinician about prescribed products, nonprescription supplements, injections, creams, and anything obtained outside a pharmacy. Do not stop or change a prescription on your own.

Less commonly, a hormone-producing condition can be involved. A high test result therefore needs interpretation in context rather than an assumption about the cause. The clinician may consider the lab’s reference range, the timing and type of test, medicines and supplements, and whether a repeat or additional tests are appropriate. This article cannot identify an individual cause from symptoms alone.

One distinction matters: external androgen use can harm the body’s own reproductive hormone signaling. In a systematic review and meta-analysis of 32 studies involving 9,371 people, anabolic steroid users had lower LH and FSH, lower sperm motility and smaller testicular size; hormone recovery after stopping varied over time (Mulawkar et al., 2023, PMID 38322636). A man can therefore have signs associated with androgen exposure while his natural hormone production or fertility is impaired. The number on a testosterone test does not capture the whole picture.

High testosterone symptoms male readers may notice

There is no reliable symptom checklist that diagnoses high testosterone. Some men notice skin or body changes; others feel no obvious difference. Research on androgen use documents acne and breast tissue growth, and reports changes in sexual function. A Danish matched cohort study of men identified as anabolic steroid users found acne, gynecomastia and erectile dysfunction were more common than in matched controls (Horwitz et al., 2019, PMID 30460728). Those findings concern steroid use, not every man with a naturally high lab result.

Fertility and testicular changes are also relevant. Anabolic steroids can suppress signals that support sperm production, and the meta-analysis above found reduced testicular size and sperm motility among users (PMID 38322636). In a smaller clinic study of 58 men, past or current steroid users commonly reported altered libido, mood changes, reduced testis volume and acne; because this was a small group of people attending a specialist clinic, those percentages should not be treated as predictions for everyone (Brower et al., PMID 11061405).

Mood, libido, skin, erections and fertility can be affected by many health conditions and medicines. They are reasons to discuss your overall health, not proof that testosterone is high. For more context, see what testosterone does in a man’s body and low testosterone symptoms in men over 50.

Are high testosterone levels good?

Not necessarily. Testosterone has normal roles in adult male health, but a higher-than-expected result does not mean better energy, strength, mood or sexual function. When levels are high because of testosterone or anabolic steroid exposure, potential effects include impaired fertility, smaller testicles, acne, breast tissue growth, elevated red blood cell counts and mood symptoms. Anawalt’s clinical review identifies erythrocytosis and infertility among established adverse effects, and notes an association between high-dose anabolic steroid use and cardiovascular disease (PMID 30753550). This evidence concerns androgen use; it does not mean a naturally higher result causes the same outcomes.

A lab result needs the lab’s units and reference interval, plus context. If you’re comparing a result with information online, remember that the clinical guideline for diagnosing low testosterone recommends symptoms together with consistently low levels confirmed on repeat morning testing. That guideline is about diagnosing deficiency, not defining a universal high threshold (Bhasin et al., 2018, PMID 29562364). Ask the clinician who ordered the test what your particular result means and whether it should be repeated.

What you can do before considering supplements

Start with information and routine care, rather than trying to push a hormone number up or down yourself.

• Make a complete product list. Include prescribed testosterone, injections, gels, gym products, supplements and any recently stopped products. Bring containers or label photos. A clinical review notes that a nonjudgmental history is a key way to identify anabolic steroid exposure (PMID 30753550).
• Keep the lab report. Record the date, test name, result, units and reference range. Ask whether the result needs confirmation and what other information is relevant. Do not use a home interpretation to diagnose yourself.
• Describe the change that prompted testing. Note when acne, breast changes, altered libido, mood changes or fertility concerns began, and whether they changed with a medicine or product. These are reported in androgen exposure research, but are not specific to it (PMIDs 30460728, 38322636).
• Discuss fertility plans and sexual symptoms plainly. Androgen exposure can suppress reproductive signaling and affect fertility (PMID 38322636). If you are using prescription testosterone, ask the prescriber how it relates to your health goals; do not alter treatment without them.
• Keep ordinary health habits steady. Aim for regular sleep, movement, balanced meals and moderation with alcohol as part of general health. These steps are not a treatment for a high testosterone result and should not replace assessment. Avoid adding a new hormone-targeting product while the cause is unclear.

For practical background, the articles on sleep and testosterone and how to increase testosterone naturally after 50 discuss habits in the context of testosterone. Neither a symptom nor a habit can establish your blood level.

What about supplements?

A supplement is not a sound way to manage a high testosterone result. Evidence about a particular ingredient cannot establish the cause of your result, and blends may not have been studied as a whole. Our scores are strict: read the male vitality supplement comparison and the ErecPrime review, which scores 2.5 out of 5 overall. A review score describes how a label compares with evidence; it does not predict a personal outcome. Talk to your doctor before taking supplements, especially if you use prescription medication. Results vary.

Frequently asked questions

Can high testosterone cause acne?

Acne is reported among men using anabolic-androgenic steroids, but acne alone cannot show that testosterone is high. Share persistent or severe acne and any hormone-related products with your clinician (PMID 30460728).

Can high testosterone affect fertility?

Androgen and anabolic steroid use can suppress reproductive hormone signals and impair sperm measures. A 32-study review found lower sperm motility and smaller testicular size among anabolic steroid users, with recovery varying (PMID 38322636). Discuss fertility concerns with a clinician.

What should I do with a high testosterone blood test?

Bring the complete report and a list of medications and supplements to the clinician who ordered it. Ask whether the test should be repeated and what may explain the result. Do not start, stop or change a prescription without medical guidance.

Are high testosterone levels good for energy or sex drive?

A high result does not promise better energy or sexual function. Symptoms vary, and androgen exposure can be associated with sexual, mood and reproductive effects (PMIDs 30460728, 30753550).

When are symptoms urgent?

Seek prompt care for a breast lump or swelling, testicular lump, or sudden libido loss with headaches or vision changes. Chest pain during sexual activity needs urgent assessment; an erection over four hours is an emergency. If you’re having thoughts of self-harm, call or text 988 in the United States. New or worsening symptoms deserve medical care.

Next step

If a lab result or a recent change has you concerned, take your report and product list to your clinician and ask what could explain it. Then use our testosterone blood test guide to prepare questions for that conversation.
