Secretion of progesterone inhibits GnRH secretion.

Question

Quizplus · Accepted Answer

Progesterone is a hormone secreted by the corpus luteum in the ovaries during the luteal phase of the menstrual cycle. Its secretion inhibits the secretion of GnRH (gonadotropin-releasing hormone) from the hypothalamus, which in turn reduces the secretion of LH (luteinizing hormone) and FSH (follicle-stimulating hormone) from the pituitary gland. This helps to maintain the uterine lining during the latter half of the menstrual cycle and prevent the development of additional follicles in the ovaries.
