Most conversations about testosterone leave women out entirely - and according to Dr. Mohit Khera, that's a serious problem. Women produce five times more testosterone than oestrogen, yet it remains the most overlooked hormone in women's health. In this episode, we sit down with one of the leading voices in testosterone science and sexual medicine to break down why the "PET triangle" (progesterone, oestrogen, and testosterone) is incomplete without all three hormones, and what women are losing by not understanding their own androgens.

We cover everything from testing correctly, to the surprising impact of the birth control pill on SHBG, to why sleep is the most underrated testosterone tool you have.

If you've ever been told your hormones are "fine" but still feel off - this episode is for you.
