About this episode

This episode explores the role of progesterone in pregnancy and fertility with Dr Raelia Lew.

Progesterone is often called the “pregnancy hormone”, but what does that actually mean for your body and your fertility? In this episode of Knocked Up, CREI fertility specialist Dr Raelia Lew unpacks how progesterone works, why timing is everything, and how this hormone helps prepare the uterus for implantation and early pregnancy. We discuss what “low progesterone” really means (and what it often does not), how levels differ in natural cycles versus IVF, and why cycle length can tell us more than a single blood test.
