Testosterone Isn't Just a Male Hormone
Women produce testosterone too — in the ovaries and adrenal glands. It plays a role in energy, mood, muscle strength, bone density, and sexual function. The problem is that testosterone levels in women decline gradually starting in the 20s and drop more sharply around menopause.
By the time a woman reaches her late 40s or 50s, her testosterone levels may be a fraction of what they were in her younger years. Yet this decline gets far less attention than the drop in estrogen.
What Women Are Actually Reporting
Low libido is the symptom most commonly linked to low testosterone in women. It's also the area where the research is most consistent. A 2019 systematic review and meta-analysis published in The Lancet Diabetes & Endocrinology — one of the most comprehensive analyses to date — looked at data from 36 randomized controlled trials involving more than 8,000 women. The researchers found that testosterone therapy was associated with meaningful improvements in sexual function, including desire, arousal, orgasm, and satisfaction, compared to placebo.
The analysis also found some improvements in overall wellbeing. But the authors were careful to note that longer-term safety data — particularly for breast cancer risk and cardiovascular effects — is still limited. That's an important caveat.
Beyond Libido: What Else Might It Help?
Some women and their doctors report improvements in energy, mood, and mental clarity with testosterone therapy. However, the research in these areas is less consistent and the studies are often smaller. The evidence is not strong enough to draw firm conclusions about these benefits yet.
There's also interest in testosterone's role in preserving bone density and muscle mass after menopause — areas where women become increasingly vulnerable. Early research is intriguing, but experts say more large, long-term studies are needed before any definitive claims can be made.
Who Might Be a Candidate?
According to clinical guidance from The Menopause Society (formerly the North American Menopause Society), testosterone therapy may be appropriate for postmenopausal women experiencing hypoactive sexual desire disorder — a persistent, distressing lack of sexual interest — when other causes have been ruled out.
It is not currently recommended as a routine treatment for fatigue, mood changes, or general aging in women without confirmed low testosterone levels and specific symptoms. Any woman considering this therapy should have a thorough evaluation and conversation with her doctor or a menopause specialist.
What You Should Know About the Risks
Testosterone therapy in women is generally given at much lower doses than in men. Side effects at appropriate doses are usually mild but can include acne, unwanted hair growth, and changes in voice if doses are too high.
The bigger open question is long-term safety. Because most studies have followed women for only 6 to 24 months, researchers don't yet have a clear picture of risks over many years — including any potential effects on breast tissue or cardiovascular health. The Lancet meta-analysis authors specifically called for larger, longer trials to fill this gap.
It's also worth knowing that no testosterone product is currently FDA-approved specifically for women in the United States. Doctors who prescribe it for women do so off-label, often using compounded or lower-dose formulations. That's not necessarily a reason to avoid it, but it does mean dosing and monitoring require extra care from a knowledgeable provider.
Natural Ways to Support Hormonal Health
If you're not ready to discuss testosterone therapy or simply want to support your hormone health naturally, there are evidence-backed lifestyle steps worth taking. Resistance exercise — lifting weights or using resistance bands — helps preserve muscle mass and may support testosterone levels. Adequate sleep is critical, since poor sleep is linked to hormonal disruption across the board. A diet rich in whole foods, healthy fats, and adequate protein also supports overall hormonal balance.
Managing chronic stress matters too. Elevated cortisol — the stress hormone — can suppress other hormones, including testosterone. Practices like mindfulness, yoga, or even regular walks have been shown to help lower cortisol over time.
The Bottom Line
Testosterone therapy for women is a legitimate area of medicine with a growing body of research behind it — particularly for improving sexual desire and satisfaction in postmenopausal women. The evidence is most solid there. For other potential benefits like energy and mood, more research is needed. Long-term safety data is still catching up. If you're experiencing symptoms that might be related to low testosterone, talk with your doctor or a menopause specialist about whether evaluation and testing make sense for you. This is one conversation worth having.
