Are progesterone shots really necessary for a frozen embryo transfer? Why would your doctor recommend intramuscular injections over suppositories or other less painful options? And could the type of progesterone you use actually affect implantation, miscarriage risk, or live birth rates?

In this episode of Brave & Curious, Dr. Lora Shahine explains the science behind progesterone support in frozen embryo transfer (FET) cycles, especially why intramuscular (IM) progesterone is often recommended in certain programmed cycle protocols.

Dr. Shahine explains how progesterone supports implantation and early pregnancy, the key differences between programmed or medicated and natural or ovulatory FET protocols, and why not all progesterone options perform the same way.

Listeners will learn how IM progesterone compares to other forms and when IM progesterone may meaningfully improve FET success. You'll get some practical guidance on how to talk with your doctor about choosing the right progesterone protocol for your body and your treatment plan.
