The menstrual cycle is composed of the follicular (proliferative), periovulatory, and luteal (secretory) phases. At periovulation, the mature follicle triggers a surge in luteinizing hormone level, causing ovum release and stimulating the residual ovarian follicle to transform into a corpus luteum. Circulating estrogen and progestin levels increase. A thickened, enriched endometrium develops owing to progestin secretion from the corpus luteum. Without fertilization, the corpus luteum atrophies, estrogen and progestin levels decline, follicle-stimulating hormone release is stimulated, and the endometrium sloughs.
