Cholesterol and Fertility: How High and Low Cholesterol Affect Your Hormones, Ovulation, and Egg Quality

Cholesterol is one of those words that can immediately make you think, "I need to lower that." But cholesterol is also essential for fertility. Your body needs cholesterol to make reproductive hormones, build healthy cells, produce bile, and support vitamin D production. So what happens when cholesterol is too high—or potentially too low—when you're trying to conceive?

In this episode, I'm breaking down what your cholesterol numbers can actually tell you about fertility, metabolic health, and hormone function. We'll look at LDL, HDL, triglycerides, ApoB, Lp(a), thyroid health, fasting insulin, nutrition, exercise, and the important difference between dietary cholesterol and blood cholesterol. Most importantly, we'll talk about why your cholesterol numbers need to be interpreted in the context of your whole body—not in isolation.
