Explanation:
Detailed explanation-1: -The hypothalamus secretes GnRH in a pulsatile fashion, which triggers FSH and LH release from the anterior pituitary. These, in turn, act on the granulosa and theca cells in the ovary to stimulate follicle maturation and trigger ovulation.
Detailed explanation-2: -In women, ovulation of mature follicles on the ovary is induced by a large burst of LH secretion-the preovulatory LH surge. Residual cells within ovulated follicles proliferate to form corpora lutea, which secrete the steroid hormones-progesterone and estradiol.
