Your Brain On... Testosterone

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.
