Question

Quizplus · Accepted Answer

During the menstrual cycle, estradiol peaks first, followed by peaks of LH and FSH, and finally, a surge of progesterone. This is known as the ovarian cycle. The surge of LH triggers ovulation and the release of a mature egg from the ovary. Progesterone helps prepare the uterus for possible implantation of a fertilized egg. Testosterone is not directly involved in the menstrual cycle.
