What Happens When a Woman Takes Testosterone?

When a woman takes testosterone at doses that keep levels in the normal female range, the best supported effect is improved sexual desire in postmenopausal women with low desire that causes distress. At higher doses, testosterone can cause acne, unwanted hair growth, and in some cases permanent changes such as a deeper voice. Results depend heavily on the dose and on careful monitoring.

Women naturally make testosterone, and levels fall gradually with age. This article explains what the research shows, what changes to watch for, what is still unproven, and how clinicians approach it. It pairs well with our guide to HRT for women and our hormone replacement therapy overview.

Does testosterone help women?

For one use, yes. The 2019 Global Consensus Position Statement on testosterone therapy for women, backed by major menopause and endocrine societies, concluded that the only evidence-based use is hypoactive sexual desire disorder (HSDD) in postmenopausal women. In trials, testosterone at levels close to the normal premenopausal range improved desire, arousal, pleasure, and the number of satisfying sexual events compared with placebo.

The same statement found the evidence was not strong enough to recommend testosterone for energy, mood, memory, bone health, or general wellbeing. Those claims are common online, but they are not established.

What changes might a woman notice on testosterone?

Changes depend on the dose and how your body responds. Benefits for desire usually take several weeks to appear, and clinicians commonly reassess after about six months. If there is no benefit by then, guidelines suggest stopping.

Effect	At levels in the female range	At higher than female levels
Sexual desire	May improve in postmenopausal HSDD	No added proven benefit
Acne and oily skin	Occasional, usually mild	More common
Facial or body hair	Occasional, usually mild	More common
Scalp hair thinning	Uncommon	Possible
Voice deepening, clitoral enlargement	Not expected	Possible and may be permanent

Is testosterone safe for women?

In trials lasting up to about two years, testosterone kept within the female physiological range did not show serious harm, and the transdermal forms did not worsen cholesterol. Long-term safety beyond that, including breast and heart safety, has not been fully established. Oral testosterone is not recommended because it can have negative effects on cholesterol. Testosterone should not be used during pregnancy because it can harm a developing baby.

Is there an FDA approved testosterone product for women?

Not in the United States. Clinicians who prescribe testosterone to women use products made for men at a fraction of the male dose, or compounded preparations. Both are off-label. The consensus statement advises against compounded testosterone when an approved product can be used, because its strength can vary. This is one reason close monitoring matters.

Who might be a candidate for testosterone?

Use this checklist to prepare for a conversation with your clinician.

• You are postmenopausal and have low sexual desire that bothers you.
• Other causes have been reviewed, such as relationship stress, depression, medicines, pain, or vaginal dryness.
• You are not pregnant, breastfeeding, or trying to conceive.
• You have no history of hormone-sensitive cancer, or you have discussed it with your oncologist.
• You are willing to have a baseline blood level and follow-up checks.

How is testosterone monitored in women?

Clinicians usually check a baseline total testosterone level, then recheck after a few weeks to confirm levels stay in the normal female range. Blood tests are used to avoid levels that are too high, not to diagnose a deficiency, since there is no testosterone level that defines a disorder in women. Regular check-ins also look for acne, hair growth, and voice changes. Learn how follow-up works on our how it works page.

Bottom line

Testosterone can help some postmenopausal women with distressing low desire when it is kept within normal female levels and monitored closely. It is not a proven treatment for energy, mood, or weight, and too much can cause lasting changes. If you are curious whether it fits your situation, start with a clinician review through our HRT for women program.
