Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): During the mid-cycle of the menstrual cycle, a rapid surge in Luteinizing Hormone (LH) induces the rupture of the Graafian follicle. Reason (R): High levels of estrogen secreted by the growing follicles exert a positive feedback on the anterior pituitary to release LH. In the light of the above sta

Step-by-step solution

Assertion (A) is true: The rapid secretion of LH leading to its maximum level during the mid-cycle (LH surge) induces the rupture of the Graafian follicle and thereby the release of an ovum (ovulation). Reason (R) is true: As the ovarian follicles grow, they secrete increasing amounts of estrogen. At high concentrations during the mid-cycle, estrogen exerts a positive feedback effect on the anterior pituitary, triggering the rapid release of LH. Therefore, Reason (R) correctly explains the physiological mechanism t
