Vedclass · Answer

(B) In a typical $28$-day menstrual cycle,the levels of $LH$ (Luteinizing Hormone) and $FSH$ (Follicle Stimulating Hormone) attain a peak level in the middle of the cycle,around the $14$th day.This rapid secretion of $LH$ is known as the $LH$ surge,which induces the rupture of the Graafian follicle and thereby leads to ovulation.Therefore,the maximum level of $LH$ occurs between the $13$th and $15$th days of the menstrual cycle.
