Question

(vii) If ruptured mature follicle is degenerated without forming corpus luteum, which of
the following is expected?
(A) ovulation will not occur
(C) pregnancy is established
(B) menstruation will not occur
(D) follicular atresia

​

Answer 1

Answer:

The answer is option (d) follicular atresia

Because, corpus luteum degenerates when pregnancy doesn't occur and it results in the breakdown of ovarian follicules (menstruation).

Answer 2

Answer:

Menstruation will not occur

Explanation:

Bcz corpus leuteum is responsible for stimulation of progesterone, a hormone that nourishes and thickens uterine lining (endometruim). Now if the ovum isn't fertilised during this period then progesterone secretion is stopped by corpus leuteum amd hence shedding of endometruim takes place resulting in menstruation. Therefore, no corpus leuteum production means no progesterone and hence no menstruation.
