Quick Summary

The luteal phase is the phase of the menstrual cycle that follows ovulation. During this phase, the ruptured ovarian follicle transforms into the corpus luteum, a temporary endocrine structure. The corpus luteum secretes progesterone and some estrogen. Progesterone prepares the uterus for the potential implantation of a fertilized egg by stimulating glandular proliferation and secretion in the endometrium. If fertilization does not occur, the corpus luteum degenerates after about 14 days, leading to menstruation and the start of a new cycle.12345

Regulation of ovarian function
This is known as the luteal phase of the menstrual cycle, which lasts until the corpus luteum degenerates (luteolysis) and estradiol and progesterone production decreases. The decreasing serum estrogen and progesterone concentrations result in constriction of uterine arteries, thus interrupting the delivery of oxygen and nutrients to the endometrium. The…
