Question

Luteinizing hormone

• A. Stimulates ovulation
• B. Stimulates the egg mother cell to undergo completion of meiotic cycle
• C. Stimulates the corpus luteum to secrete progesterone
• D. All of the above

Answer 1

Answer: (D)

All of the above

In females, ovulation of mature follicles on the ovary is induced by LH secretion known as the preovulatory LH surge. Residual cells within ovulated follicles proliferate to form corpus luteum, which secretes the steroid hormones progesterone and estradiol. Progesterone is necessary for the maintenance of pregnancy, and, in most mammals, LH is required for continued development and function of corpora lutea. The name luteinizing hormone derives from this effect of inducing luteinization of ovarian follicles.
