Question

Quizplus · Accepted Answer

After ovulation, the endometrium enters its secretory phase. This is because the surge in luteinizing hormone (LH) that triggers ovulation also causes the ruptured follicle to develop into the corpus luteum, which secretes progesterone. Progesterone stimulates the endometrium to enter its secretory phase, readying it for potential implantation of a fertilized egg.

Answer: D 
 After ovulation, the ruptured follicle develops into the corpus luteum. The corpus luteum produces both progesterone and estrogen, but after about 10-14 days, if there is no fertilized egg to maintain its presence, the corpus luteum will start to degenerate and become a corpus albicans. This process marks the end of the menstrual cycle and the beginning of a new follicular phase.

Choices A and C are incorrect because they are not accurate descriptions of events that occur after ovulation.
