Progesterone

Vedclass · Answer

(A) The menstrual cycle is regulated by hormones. During the luteal phase,the corpus luteum secretes large amounts of progesterone,which is essential for maintaining the endometrium. If fertilization does not occur,the corpus luteum degenerates,leading to a sharp decrease in the levels of progesterone. This withdrawal of progesterone causes the breakdown of the endometrial lining and its blood vessels,which results in menstruation.
