Progesterone

Vedclass · Answer

(D) The menstrual cycle is regulated by the levels of ovarian hormones,specifically estrogen and progesterone.Progesterone is essential for maintaining the endometrium (the lining of the uterus) during the secretory phase of the menstrual cycle.When an ovum is not fertilized,the corpus luteum degenerates,leading to a sharp decline in the levels of progesterone.The withdrawal or sudden decrease of progesterone causes the breakdown of the endometrial lining,which results in menstruation.Therefore,the withdrawal of progesterone is the primary trigger for the onset of menstruation.
