Vedclass · Answer

(D) The correct answer is $D$. In a regularly cycling human female,the most common physiological reason for the cessation of menstruation is pregnancy,which occurs following the fertilization of the ovum. $1$. Upon fertilization,the embryo secretes $hCG$ (human Chorionic Gonadotropin),which maintains the corpus luteum. $2$. The corpus luteum continues to secrete high levels of progesterone and estrogen,which prevent the shedding of the endometrial lining. $3$. Consequently,the menstrual cycle is suspended to support the developing embryo.

Which one of the following is the most likely root cause why menstruation is not taking place in a regularly cycling human female?
