Most people worry about low testosterone, not high testosterone. But levels that climb too far can cause real health problems, including acne, mood swings, and a higher risk of heart issues. High testosterone usually does not happen on its own. It is almost always triggered by a specific medical condition, a medication, or a supplement that mimics the hormone. Understanding what pushes testosterone up is the first step to knowing whether you need testing or treatment.
What Is Considered High Testosterone?
Testosterone levels are measured with a blood test. For adult men, the normal range is roughly 300 to 1,000 nanograms per deciliter (ng/dL). For adult women, the normal range is much lower, usually between 15 and 70 ng/dL. These ranges can vary slightly depending on the laboratory.
High testosterone is diagnosed when levels consistently exceed the upper limit of the normal range for your sex and age. A single elevated reading does not always mean a chronic problem. Testosterone fluctuates throughout the day, peaking in the morning, so doctors often repeat the test to confirm a high result.
For men, levels above 1,000 ng/dL are generally considered high. For women, levels above 70 ng/dL may be considered elevated, though symptoms matter just as much as the number.
Medical Conditions That Raise Testosterone
Several underlying health conditions can cause the body to produce too much testosterone. These are the most common medical triggers.
Polycystic ovary syndrome (PCOS) is the leading cause of high testosterone in women. It affects the ovaries and causes them to produce excess androgens, including testosterone. PCOS affects an estimated 6 to 12 percent of women of reproductive age. Along with high testosterone, it often causes irregular periods, ovarian cysts, and excess facial or body hair.
Congenital adrenal hyperplasia is a genetic condition that affects the adrenal glands. These glands sit on top of the kidneys and produce hormones, including testosterone. In this condition, the body cannot make cortisol properly, so it overproduces other hormones instead, including androgens. Both men and women can have this condition, and it can cause high testosterone levels from birth or later in life.
Adrenal tumors and ovarian tumors can also produce testosterone directly. These are rare but serious causes. A tumor in the adrenal gland or ovary that secretes testosterone will typically cause very high levels and rapid onset of symptoms. Anyone with suddenly severe symptoms should see a doctor promptly.
Thyroid disorders can indirectly affect testosterone levels. Both an overactive and underactive thyroid can disrupt the balance of sex hormones, though the effect is often complex. Some research suggests thyroid dysfunction can alter testosterone metabolism, but it is not the most common cause of high levels.
Medications and Supplements That Trigger High Testosterone
Some prescription medications and over-the-counter products can raise testosterone. This is a common and often overlooked trigger.
Testosterone replacement therapy (TRT) is the most obvious cause. Men prescribed testosterone gel, injections, or patches for low testosterone can see their levels climb too high if the dose is too strong. Regular blood testing is standard practice during TRT to keep levels in range.
Anabolic steroids are synthetic versions of testosterone. People who use them for muscle building often have very high testosterone levels. These drugs carry serious health risks, including liver damage, heart problems, and psychiatric effects. Long-term use can also shut down the body’s natural testosterone production.
Certain supplements claim to boost testosterone naturally. The evidence for most of these products is limited. Some supplements contain ingredients that can act like hormones in the body, and a few have been found to contain undeclared steroid-like compounds. The FDA does not regulate supplements the same way it regulates prescription drugs, so the actual contents can differ from the label. Some research suggests DHEA, a supplement sold over the counter, can raise testosterone because the body converts it into testosterone.
Some medications used for other conditions can affect testosterone. Certain seizure medications, opioids, and glucocorticoids can alter hormone levels, though the effects vary widely by individual and drug.
Lifestyle Factors That Influence Testosterone
Lifestyle choices generally do not push testosterone into the dangerously high range, but they can influence levels within and slightly above the normal range.
Resistance training causes a temporary spike in testosterone. Heavy weightlifting can raise testosterone for a short period after exercise. This spike usually returns to baseline within an hour. It is a normal physiological response, not a cause of chronically high levels.
Sleep plays a major role in testosterone production. Most testosterone is released during sleep, particularly during REM sleep. Studies have shown that getting fewer than five hours of sleep per night can lower testosterone by 10 to 15 percent. Getting adequate sleep helps maintain normal production but will not cause supraphysiological levels.
Diet has a modest effect on testosterone. Severe calorie restriction can lower testosterone, while eating enough calories and maintaining a healthy weight supports normal production. No specific food has been proven to raise testosterone to unhealthy levels.
Stress generally lowers testosterone rather than raising it. Cortisol, the stress hormone, tends to suppress testosterone production. Chronic stress is more likely to cause low testosterone than high.
Symptoms of High Testosterone
Symptoms differ between men and women. Recognizing them can help you decide whether to get tested.
In men, high testosterone can cause:
- Acne and oily skin
- Mood swings, irritability, or aggression
- Increased body hair
- Sleep apnea
- Reduced sperm count and fertility problems
- Enlarged prostate symptoms
In women, high testosterone can cause:
- Irregular or absent menstrual periods
- Excess facial and body hair (hirsutism)
- Acne
- Deepening of the voice
- Male-pattern baldness
- Enlarged clitoris
Many of these symptoms overlap with other conditions. Acne alone does not mean you have high testosterone. A blood test is the only reliable way to confirm elevated levels.
Health Risks of Chronically High Testosterone
Sustained high testosterone is not harmless. Research has linked it to several health concerns.
Cardiovascular risk is a significant concern. Some studies have found that men with very high testosterone levels, particularly those using anabolic steroids, have an increased risk of heart attack and stroke. The evidence is strongest for supraphysiological doses from steroid use rather than naturally elevated levels.
Fertility problems can occur in men. High testosterone signals the brain to stop producing luteinizing hormone and follicle-stimulating hormone, which are needed for sperm production. This is why men using anabolic steroids often become temporarily infertile.
Prostate health is another concern for men. Testosterone does not cause prostate cancer directly, but it can fuel the growth of existing prostate cancer cells. Men with high testosterone should discuss prostate monitoring with their doctor.
Mood and behavior changes can affect quality of life. Some research links very high testosterone to increased irritability and impulsive behavior, though individual responses vary widely.
When to See a Doctor
You should see a doctor if you have symptoms of high testosterone that persist, especially if they develop suddenly. Sudden onset of symptoms like voice deepening, rapid hair growth, or severe acne warrants prompt evaluation because it can signal a tumor.
Testing for high testosterone involves a simple blood draw. Your doctor may order a total testosterone test, a free testosterone test, or both. Free testosterone is the portion of the hormone that is active in the body. Depending on the results, your doctor may order additional tests to check for underlying conditions like PCOS or adrenal disorders.
Treatment depends entirely on the cause. If a medication is responsible, adjusting the dose may solve the problem. If a tumor is found, surgery may be needed. For PCOS, treatment often focuses on managing symptoms with birth control pills or other medications that block androgen effects. Never attempt to lower testosterone on your own by taking unregulated supplements or stopping prescription medications without medical supervision.
Frequently Asked Questions
Can high testosterone be caused by diet?
No specific food has been proven to cause chronically high testosterone. Diet has a modest effect on hormone levels, but severe overproduction is almost always due to a medical condition, medication, or supplement.
What happens if a woman has high testosterone?
Women with high testosterone often experience irregular periods, acne, and excess facial or body hair. The most common cause is PCOS, which affects an estimated 6 to 12 percent of women of reproductive age.
Is high testosterone dangerous for men?
Chronically high testosterone can increase cardiovascular risk and reduce sperm count. Men using anabolic steroids or excessive testosterone replacement therapy are at the highest risk for these complications.
How is high testosterone treated?
Treatment depends on the underlying cause. Doctors may adjust medications, treat the underlying condition like PCOS, or remove a tumor if one is found. Always work with a doctor to determine the right approach.
