Question

Quizplus · Accepted Answer

The shedding of the endometrial (uterine) lining occurs as a result of a fall in plasma levels of estradiol and progesterone. This occurs because the corpus luteum, which secretes these hormones, degenerates if fertilization and implantation do not occur. The fall in hormone levels triggers the shedding of the endometrial lining during menstruation.
