The Truth About Progesterone Levels in Fertility, IVF, and Early Pregnancy

Download The Physician Fertility Roadmap- a 6-step, evidence-based plan to optimize your fertility over the next 6-12 months. https://support.loveandsciencefertility.com/The-Physician-Fertility-RoadmapProgesterone is one of the most talked-about — and most misunderstood — hormones in fertility care.Patients are often told to “check their progesterone,” but what do these numbers actually mean? Can they predict whether a cycle will succeed or fail? And how should progesterone be interpreted in natural cycles, IVF, or early pregnancy?In this episode, Dr. Erica Bove explains the physiology of progesterone, why levels fluctuate throughout the luteal phase, and why a single blood test often provides an incomplete picture.She discusses how progesterone functions in ovulation, implantation, pregnancy maintenance, and assisted reproduction — and why clinical history frequently matters more than any single laboratory value.In this episode, you’ll learn:• How progesterone is produced after ovulation• Why progesterone secretion is pulsatile and difficult to interpret• What a mid-luteal progesterone level can actually tell you• How progesterone monitoring differs in natural cycles vs IVF cycles• Evidence around progesterone thresholds in frozen embryo transfer• The role of progesterone in pregnancy maintenance• When progesterone supplementation may be helpful• Why frequent hormone checking can sometimes increase anxiety without improving outcomesThis conversation is designed to help you better understand your body, your treatment experience, and the science behind progesterone — while also providing clarity in an area that often feels confusing or overwhelming.If you are navigating fertility treatment or trying to understand hormone testing, this episode offers both evidence-based insight and compassionate perspective.This episode is part of Season 1 of The Love & Science Fertility Framework: The Biology Beneath the Surface — a clinical series examining the physiology that drives reproductive outcomes.
