Progesterone: Why Delivery Method Matters for Brain, Uterus & Breast Health

In this episode, Dr. Brendan McCarthy, Chief Medical Officer of Protea Medical Center, explains why progesterone delivery systems matter—and how different routes change what progesterone actually does in the body.

Part 4 of the progesterone series covers oral, topical, vaginal, rectal, injectable, and sublingual progesterone, breaking down which methods affect the brain, uterus, and breast tissue—and why choosing the right route is critical.

If progesterone hasn’t worked for you in the past, the issue may not be the dose, but how it was delivered.

This episode focuses on education, patient agency, and thoughtful hormone care—no shortcuts, no selling.
