Vedclass · Answer

(D) The menstrual cycle is regulated by the hormones oestrogen and progesterone. When the ovum is not fertilized,the corpus luteum degenerates,leading to a sharp decrease in the levels of progesterone and oestrogen. This withdrawal of hormones causes the constriction of the uterine blood vessels,which leads to the ischemia (lack of blood supply) of the uterine endometrium. Consequently,the uterine epithelium (endometrium) sloughs off,resulting in menstruation.
