High testosterone in women is treatable, and the right approach depends on what’s driving it. Normal testosterone for women falls between 15 and 70 ng/dL, and levels above that range can cause symptoms like excess facial or body hair, acne, thinning scalp hair, and irregular periods. Most treatment plans combine medications that lower testosterone or block its effects with lifestyle changes that address the underlying cause.
Why Testosterone Gets Too High
The most common cause is polycystic ovary syndrome (PCOS), which affects roughly 1 in 10 women of reproductive age. In PCOS, the ovaries produce more androgens than normal, often because the body has become resistant to insulin. When cells don’t respond well to insulin, the pancreas pumps out more of it, and high insulin levels signal the ovaries to ramp up testosterone production. This insulin connection is why metabolic treatments play such a big role in managing the condition.
Less commonly, high testosterone comes from the adrenal glands rather than the ovaries. A condition called nonclassic congenital adrenal hyperplasia (NCAH) can look a lot like PCOS, with excess hair growth, irregular periods, and fertility problems. The distinction matters because the treatment is different: NCAH is managed with low-dose cortisol replacement rather than the anti-androgen medications used for PCOS. Ovarian or adrenal tumors are rare causes but are usually ruled out with imaging if testosterone levels are very high.
Getting a clear diagnosis before starting treatment saves time and frustration. A blood test measuring total testosterone, free testosterone, and often insulin and a hormone called DHEA-S can help pinpoint the source.
How Birth Control Lowers Free Testosterone
Combined oral contraceptives (the pill containing both estrogen and progestin) are one of the most widely prescribed first-line treatments. They work through a two-step mechanism. First, the estrogen component stimulates the liver to produce more of a protein called sex hormone-binding globulin (SHBG). SHBG acts like a sponge, binding to testosterone in the bloodstream so it can’t activate receptors in the skin and hair follicles. Second, the progestin component helps suppress the ovaries’ androgen production directly.
The effect on SHBG is substantial. In clinical testing, certain formulations increased SHBG concentrations by as much as 175% and boosted its binding capacity by up to 330%. Total testosterone dropped by about 16%, and the biologically active fraction, free testosterone, fell by roughly 35%. Not all pills are equally effective here. Formulations with newer progestins that have less androgenic activity tend to work better than older ones. Your prescriber will typically choose a pill with a progestin like drospirenone, desogestrel, or norgestimate for this reason.
Most women notice improvements in acne within two to three months. Hair-related changes take longer because hair follicles cycle slowly.
Anti-Androgen Medications
When birth control alone isn’t enough, or when symptoms like unwanted hair growth are severe, an anti-androgen medication is often added. Spironolactone is the most commonly used option. It works by blocking the receptors that testosterone and its more potent form (DHT) activate in the skin, oil glands, and hair follicles. The standard dose ranges from 100 to 200 mg daily, split into two doses. It’s frequently prescribed alongside birth control both for better results and because spironolactone can cause birth defects and requires reliable contraception.
Spironolactone was originally developed as a blood pressure medication, so it can lower blood pressure slightly and increase potassium levels. Periodic blood work to check potassium is typical during treatment. Side effects like breast tenderness, fatigue, or spotting between periods usually improve after the first few months.
Targeting Insulin Resistance
If insulin resistance is part of the picture, addressing it can lower testosterone at its source. Metformin, a medication used to improve insulin sensitivity, reduced testosterone levels by 23% and insulin levels by 25% in studies using a dose of 1,500 mg per day. By bringing insulin down, metformin removes the signal that tells the ovaries to overproduce androgens. It can also help restore regular ovulation, which is why it’s commonly used in women with PCOS who are trying to conceive.
Myo-inositol, a supplement available over the counter, has gained attention as a more natural alternative. A meta-analysis of randomized trials found no statistically significant difference between myo-inositol and metformin in their effects on testosterone, BMI, or insulin resistance markers over treatment periods up to six months. For women who prefer a supplement-first approach or who experience gastrointestinal side effects from metformin (which are common, especially early on), myo-inositol at doses of 2,000 to 4,000 mg daily is a reasonable option to discuss with a provider.
Lifestyle Changes That Move the Needle
Weight loss, even a modest 5 to 10% of body weight, can meaningfully reduce testosterone in women whose high levels are linked to insulin resistance. Losing weight improves insulin sensitivity, which lowers insulin, which in turn reduces the ovarian signal to produce excess androgens. The type of diet matters less than the overall reduction in body fat, though eating patterns that stabilize blood sugar (more fiber, protein, and healthy fats; fewer refined carbohydrates) tend to complement the hormonal goals.
Regular exercise, particularly a combination of strength training and cardiovascular activity, independently improves insulin sensitivity. Even without weight loss, consistent physical activity can lower circulating androgens and improve menstrual regularity. Aiming for 150 minutes of moderate exercise per week is a practical starting point. Sleep also plays a role: chronic sleep deprivation worsens insulin resistance, creating a cycle that can keep testosterone elevated.
Managing Unwanted Hair Growth
Excess hair (hirsutism) is often the symptom women find most distressing, and it’s also the slowest to respond to treatment. Hair follicles have a growth cycle of several months, so even after testosterone levels normalize, existing hairs will continue to grow for a while. Medications typically take weeks to months before visible results appear, and many women don’t see the full benefit for six months or more.
Because of this delay, combining hormonal treatment with direct hair removal gives faster visible improvement. Laser hair removal and electrolysis are the most effective long-term options. Laser works best on dark hair against lighter skin tones, while electrolysis works on all hair and skin colors but treats one follicle at a time.
A prescription cream containing eflornithine can slow facial hair regrowth between removal sessions. Applied twice daily to affected areas, it inhibits an enzyme hair follicles need to grow. In clinical trials, 35% of women using eflornithine saw significant improvement after 24 weeks, compared with 9% using a placebo. After applying, you should wait at least four hours before washing the area. Sunscreen and cosmetics can go on top once the cream has dried. If you’re also waxing or tweezing, apply the cream at least five minutes after hair removal.
When the Cause Is Adrenal
If testing reveals that high testosterone is coming from the adrenal glands rather than the ovaries, treatment shifts to cortisol replacement. In nonclassic congenital adrenal hyperplasia, the adrenal glands lack enough of a specific enzyme to produce cortisol efficiently. The body compensates by overdriving the adrenal pathway, which generates excess androgens as a byproduct. Low-dose cortisol replacement calms this overproduction. Not everyone with NCAH needs medication. Treatment is typically recommended only when symptoms are present: excess hair growth, irregular cycles, or difficulty getting pregnant.
What a Realistic Timeline Looks Like
Acne tends to improve within two to three months of starting hormonal treatment. Menstrual cycles often regulate within a similar timeframe. Hair growth is the most stubborn symptom. New hair may grow in thinner and lighter after three to six months of treatment, but existing terminal (coarse, dark) hairs generally need physical removal. Most dermatologists recommend committing to at least six to twelve months of consistent treatment before judging whether a medication is working for hirsutism.
Testosterone levels on blood work can drop within weeks of starting medication, but the physical changes lag behind the lab numbers. This gap is normal and doesn’t mean treatment is failing. Sticking with the plan and rechecking labs at three-month intervals gives the clearest picture of progress.
