Question
Given below are two statements:
Statement I : Ovulation is caused by LH surge leading to rupture of Graafian follicles.
Statement II: Graafian follicle remaining after ovulation transform into corpus luteum and secretes large amount of estrogen.

A.Statement I is correct but Statement II is incorrect
B.Statement I is incorrect but Statement II is correct
C.Both Statement I and Statement II are correct
D.Both Statement I and Statement II are incorrect
Solution
Sol. [Key Concept: Ovulation triggered by the LH surge]
Rapid secretion of LH leading to its maximum level during the mid-cycle called LH surge induces rupture of Graafian follicle and thereby the release of ovum (ovulation).
The remaining parts of the Graafian follicle transform as the corpus luteum, which secretes large amounts of progesterone.
