Luteal Phase Defect & Progesterone: When It Matters, When It Doesn’t | Dr Parry Explains The Research

Luteal phase defect is one of the most hotly debated topics in fertility right now. Do you actually have it? And do you really need progesterone support… or not? In this episode, I sit down with reproductive endocrinologist and researcher Dr. Parry to unpack what the science actually says about luteal phase defects, progesterone supplementation, and fertility treatment. We cover: what a luteal phase defect is (and what it isn’t), when a short luteal phase or low progesterone is worth taking seriously, and when adding more progesterone doesn’t change outcomes. We also talk through the differences between progesterone support in natural cycles, IUI, IVF, and early pregnancy. If you’ve been told you might have a luteal phase defect, are wondering whether to push for progesterone, or just want a clear, calm breakdown of the research… this episode is for you.
