Testosterone as a Neuroprotective Hormone

In this powerful episode, board-certified urologist Dr. Kelly Casperson exposes the gender bias in medicine and reveals why testosterone may be the missing link in women’s mood, motivation, and longevity.

One of the few female urologists in the U.S., Dr. Kelly is rewriting the narrative on hormones—explaining why testosterone isn’t “just for men” and why, after 90 years, the FDA still hasn’t approved it for women.

Her message is clear: women are not broken. Whether you’re in your 30s, perimenopause, or beyond, this episode will change how you see your biology—and your power.
