Vedclass · Answer

(A) The menstrual cycle is regulated by various hormones. During the follicular phase,estrogen levels rise,which triggers a surge in the secretion of Luteinizing Hormone $(LH)$ from the anterior pituitary gland. This phenomenon is known as the $LH$ surge. This peak level of $LH$ induces the rupture of the mature Graafian follicle,leading to the release of the secondary oocyte,a process called ovulation. Therefore,a high concentration of $LH$ (not low) is required for ovulation,and high estrogen levels are the primary trigger for this $LH$ surge.

Which of the following hormone levels causes the release of an ovum from the Graafian follicle (ovulation)?
