Diagram Description

Menstrual Cycle Hormones

The diagram shows the levels of FSH, LH, oestrogen, and progesterone during a typical 28-day menstrual cycle. FSH rises early in the cycle, stimulating follicle growth. Oestrogen levels increase as the follicle develops, peaking just before ovulation. LH surges sharply at ovulation. Progesterone rises after ovulation and remains high if pregnancy occurs.
