Question

Quizplus · Accepted Answer

The proliferative phase of the uterine cycle refers to the estrogen-induced thickening of the endometrium. Progesterone plays a role in the later secretory phase of the cycle, while hCG is only produced during pregnancy. The deterioration of the corpus luteum into the corpus albicans occurs in the absence of fertilization and is not specific to the uterine cycle.
