Testosterone for women: what the evidence actually shows vs. what social media is selling you.

Testosterone has become the hormone every midlife woman is told she is missing: the third hormone lost at menopause, the fix for brain fog, low energy, stubborn weight, and thinning muscle.

The science tells a different and more reassuring story.

In this episode, Dr. Ayesha Sherzai sits down with Professor Susan Davis, MBBS, FRACP, PhD, the clinician-researcher and academic endocrinologist who gathered much of the data and helped write the global guidelines, to separate what the research supports from what is simply being sold.

In this episode:

Why testosterone does not crash at menopause the way estrogen does, and what actually changes across a woman's life
What the research shows about testosterone and memory, brain fog, and dementia risk
The real story on testosterone for muscle, bone, and anti-aging claims
Why women tend to gain a little weight on testosterone rather than lose it
The one use with genuine evidence behind it: low sexual desire after menopause that causes real distress
Why more is not better, and what high-dose testosterone actually does
What is really inside compounded creams, injections, and testosterone pellets sold at med spas
Why routine testosterone blood testing generates bills and anxiety rather than answers
Why there is no such thing as testosterone deficiency in women
How to tell an evidence-based clinician from a sales pitch
What genuinely protects a woman's aging brain, and why connection matters more than any hormone

Professor Susan Davis is a consulting endocrinologist at Monash University in Melbourne, where she directs a leading women's health research program. She has studied testosterone in women since the 1990s and is the lead author of the Global Consensus Position Statement on the Use of Testosterone Therapy for Women, endorsed by the International Menopause Society, The Endocrine Society, and menopause and obstetric societies around the world.
