What Is High Testosterone in Women? Causes and Symptoms

High testosterone in women means levels above roughly 55 ng/dL of total testosterone for those under 60, or above 32 ng/dL for women over 60. Women naturally produce testosterone in their ovaries and adrenal glands, and it plays a role in bone strength, muscle maintenance, and sex drive. Problems arise when levels climb above the normal range, triggering a cascade of physical changes and raising the risk of metabolic conditions over time.

Normal Testosterone Levels in Women

For women between 18 and 60, the typical total testosterone range is 9 to 55 ng/dL. After age 60, that window narrows to 5 to 32 ng/dL as the ovaries produce less. But total testosterone only tells part of the story. Most testosterone in the bloodstream is bound to a carrier protein called sex hormone-binding globulin (SHBG), making it inactive. Only the small unbound fraction, called free testosterone, actually affects your tissues.

Free testosterone ranges shift with age. Between 18 and 30, a normal reading falls between 0.8 and 7.4 pg/mL. For women 31 to 40, it’s 1.3 to 9.2 pg/mL. After menopause, the range drops to 0.6 to 3.8 pg/mL. A woman can have a normal total testosterone level but still experience symptoms of excess if her SHBG is low, because more of that testosterone is unbound and active. This is why clinicians often calculate a free androgen index, a ratio of total testosterone to SHBG, to get a more accurate picture of how much testosterone is actually doing work in the body.

What High Testosterone Feels Like

The signs tend to show up gradually, and many women attribute them to stress or aging before getting tested. The most common symptoms include:

  • Excess hair growth (hirsutism): coarse, dark hair on the upper lip, chin, chest, abdomen, or back, distinct from fine “peach fuzz”
  • Acne and persistently oily skin, often along the jawline and chin
  • Irregular or absent periods
  • Thinning hair at the front of the scalp on both sides, following a male pattern
  • Difficulty getting pregnant

At more extreme levels, other changes can develop: a deepening voice, increased muscle mass, a shift in body shape away from typical female fat distribution, decreased breast size, and enlargement of the clitoris. These more pronounced changes usually signal significantly elevated levels rather than a mild excess.

Common Causes

Polycystic ovary syndrome (PCOS) is by far the most frequent cause of high testosterone in women of reproductive age. The ovaries overproduce androgens, often alongside insulin resistance, which further drives testosterone up. Not every woman with PCOS has visibly high testosterone on a blood test, but the free androgen index is frequently elevated even when total levels look normal.

Congenital adrenal hyperplasia is another cause. In this condition, the adrenal glands produce excess androgens due to an enzyme deficiency present from birth. A milder, late-onset form sometimes goes undiagnosed until adulthood, when symptoms like hirsutism or irregular cycles prompt testing.

Less commonly, tumors on the ovaries or adrenal glands can secrete testosterone directly. These tend to cause a rapid, dramatic rise in levels rather than the slow creep seen with PCOS. Certain medications and anabolic steroid use can also push testosterone well above normal ranges. Obesity plays a role too: excess fat tissue alters hormone metabolism and can lower SHBG, effectively increasing the amount of active testosterone in circulation.

Metabolic and Cardiovascular Risks

High testosterone isn’t just a cosmetic concern. Research on women aged 65 and older found that those with higher total and free testosterone were significantly more insulin resistant, had greater rates of metabolic syndrome, and were more likely to have cardiovascular disease. The metabolic syndrome cluster linked to elevated testosterone includes abdominal obesity, high triglycerides, low HDL (“good”) cholesterol, high blood pressure, and elevated fasting blood sugar.

In younger women with PCOS, insulin resistance and high testosterone often feed each other in a cycle. Excess insulin stimulates the ovaries to produce more androgens, and those androgens in turn promote fat storage around the midsection, which worsens insulin resistance. Over time, this pattern raises the risk of developing type 2 diabetes, fatty liver disease, and heart problems well before the age those conditions typically appear.

How Testosterone Is Tested

Timing matters for an accurate result. Testosterone levels fluctuate throughout the menstrual cycle and across the day. Blood draws taken in the morning, generally between 8:30 a.m. and noon, produce the most reliable readings. For women who are still cycling, a sample taken around day 15 of the menstrual cycle (roughly mid-cycle) correlates most strongly with a woman’s true average testosterone level, with a reliability correlation of 0.75 in research.

Your provider will typically order both total testosterone and either free testosterone or SHBG so the free androgen index can be calculated. If total testosterone comes back normal but symptoms persist, a low SHBG level may reveal that more testosterone is biologically active than the total number suggests. Additional tests for related hormones from the adrenal glands and ovaries help pinpoint whether the source of excess production is one organ or the other.

Treatment Options

Treatment depends on the underlying cause and which symptoms bother you most. For PCOS-related high testosterone, addressing insulin resistance is often the first step. Medications that improve how the body handles insulin can directly reduce ovarian androgen production, even through insulin-independent pathways that act on the ovarian cells themselves.

Anti-androgen medications work by blocking testosterone from binding to receptors in hair follicles, skin, and other tissues. These are commonly prescribed for hirsutism and acne. Because they can affect a developing fetus, they’re used alongside reliable contraception. Hormonal birth control is another mainstay: it raises SHBG, which binds up more free testosterone, and suppresses ovarian androgen production simultaneously. Many women notice improvements in acne, hair growth, and cycle regularity within three to six months.

Combination approaches tend to outperform single treatments. A six-month clinical trial published in the Journal of Clinical Endocrinology & Metabolism found that using an anti-androgen alongside an insulin-sensitizing medication together produced better results than either one alone in women with PCOS.

Lifestyle Factors That Help

Weight loss, even a modest 5 to 10 percent of body weight, can meaningfully lower testosterone levels in women who are overweight. Losing abdominal fat specifically reduces insulin resistance, which in turn dials down the signal telling the ovaries to overproduce androgens. Exercise amplifies this effect by improving insulin sensitivity independently of weight change.

Dietary patterns play a role as well. Diets high in processed foods, excess sugar, and saturated fat promote the kind of inflammation and fat accumulation that worsens hormonal imbalances. Fiber-rich diets that include plenty of vegetables, whole grains, and healthy fats tend to support better SHBG levels and more stable blood sugar. The specific “best” diet for lowering testosterone in women hasn’t been definitively established, but the consistent finding across research is that reducing insulin resistance through any sustainable eating pattern improves androgen levels.

Stress management matters too, since chronic stress drives cortisol production from the same adrenal glands that produce androgens. The adrenal pathway can contribute a meaningful share of total testosterone, particularly in women who’ve already gone through menopause and no longer produce significant ovarian androgens. Regular sleep, physical activity, and stress reduction support the hormonal environment that keeps testosterone in a healthy range.
