Testosterone Side Effects in Women: What to Watch

Save

Testosterone in women can cause androgenic side effects — acne, oily skin, and increased facial or body hair — that are usually dose-related and often reversible. Higher, supraphysiologic doses raise the chance of voice changes and other lasting effects. The one evidence-based use is low desire after menopause [1].

Why do some women take testosterone at all?

Testosterone is present in women at levels roughly 10 to 20 times lower than in men, and it drifts down gradually with age rather than dropping sharply at menopause. In the United States no testosterone product is approved specifically for women, so it is prescribed off-label. According to the 2019 global consensus statement endorsed by the Endocrine Society and the International Menopause Society, the single evidence-based indication is hypoactive sexual desire disorder in postmenopausal women — persistent low desire that causes distress 1. Concerns like this are assessed within the wider frame of female sexual function and relationships 2. Even then, the desire benefit is modest, and it sits alongside other approaches to low sexual desire and to menopause treatment.

What androgenic side effects should you watch for?

Acne, oily skin, and increased facial or body hair are the most common side effects of testosterone in women, and they track closely with dose 1. The Endocrine Society's hirsutism guidance describes how excess androgen drives coarse, dark hair growth in a male-like pattern across the face, chest, and abdomen 3. In trials using physiologic doses — levels kept within the normal premenopausal range — acne and unwanted hair were only slightly more common than with placebo, bothering fewer than 1 in 10 women 1. Most changes are mild and tend to ease within about 3 to 6 months when the dose is reduced. Scalp thinning can also occur, echoing the pattern behind some menopausal hair changes.

Which changes can become permanent?

A handful of masculinizing changes can persist even after testosterone is stopped, which is why higher doses carry greater stakes. Voice deepening, clitoral enlargement, and male-pattern scalp hair loss are the effects most likely to become permanent, whereas acne and mild extra hair usually reverse once the dose comes down 1. These lasting changes, grouped together as virilization, become far more likely when blood testosterone climbs well above the normal premenopausal range 1. Virilization is uncommon at carefully monitored physiologic doses, according to the 2019 consensus statement, which recommends against any regimen that pushes levels into the male range 1. Trial safety data extend to only about 24 months, so effects beyond that are less certain 1. Noticing a deepening voice or new coarse hair early gives the best chance to adjust before changes set in.

Why does dosing and delivery route matter so much?

Side-effect risk rises steeply when blood testosterone moves above the premenopausal range, so how a dose is delivered matters as much as the amount. Compounded pellets implanted under the skin and high-dose injections are the routes most likely to produce supraphysiologic peaks, and the 2019 global consensus recommends against pellets and injectable testosterone for this reason 1. Transdermal creams or gels formulated for the female range allow steadier, lower levels and easier adjustment 1. Life stage shapes the picture too: in the reproductive years, high androgen signs more often point to PCOS than to treatment, while after menopause low desire is the usual reason testosterone is weighed 3. Baseline and follow-up blood levels help keep therapy in the safe range.

When testosterone side effects need a clinician

A clinician experienced in menopause or hormonal health can weigh whether testosterone is reasonable for you, check baseline and periodic blood levels, and match the dose and route to keep androgenic effects unlikely. According to the 2019 consensus statement, monitoring blood testosterone every 3 to 6 months early on helps catch levels creeping above the female range before side effects appear 1. Someone with new acne, unwanted hair, or a voice change on therapy has a clear reason to revisit the plan. Gale can help you prepare for that conversation with the right questions and history in hand.

Common questions

No. There is no testosterone product approved specifically for women in the US, so when it is used it is prescribed off-label, most often for low sexual desire after menopause. Products made for men deliver much higher doses, which raises the chance of androgenic side effects.

Many are. Acne, oily skin, and mild extra hair usually fade once the dose is lowered. A few changes — voice deepening, clitoral enlargement, and male-pattern scalp hair loss — can persist, which is why keeping blood levels in the normal female range matters.

Pellets and injections can push blood testosterone above the premenopausal range, where masculinizing effects become far more likely. The 2019 global consensus statement recommends against these routes and favors low-dose creams or gels that allow steadier levels and easier adjustment.

The evidence does not support testosterone for hot flashes, mood, or bone strength in women. Its one evidence-based use is low sexual desire after menopause. Other menopause symptoms are usually addressed with different treatments better matched to them.

When to check in about testosterone

  • —A deepening or hoarse voice, or new male-pattern scalp hair loss, while on testosterone is a reason to seek prompt clinician review.
  • —Rapidly worsening acne or fast-spreading facial or body hair is a reason to have your dose and blood levels rechecked.
  • —Clitoral enlargement or other genital changes is a reason to seek clinician review before continuing.
  • —Blood testosterone measured above the normal premenopausal range is a reason to review the dose and delivery route with your prescriber.

This article is general health education, not medical advice. Whether testosterone is appropriate, and at what dose and route, is a decision to make with a clinician experienced in menopause or hormonal health who knows your full history.
