Question

What stimulates ovulation and conversion of the follicle to the corpus luteum at day 14 of the cycle?

A) Estrogen
B) Progesterone
C) Luteinizing hormone (LH)
D) Follicle-stimulating hormone (FSH)

Answer 1

Luteinizing hormone (LH) stimulates ovulation and the formation of the corpus luteum at day 14 of the menstrual cycle.

Step-by-step explanation:

Ovulation is stimulated by the surge of luteinizing hormone (LH) that occurs at day 14 of the menstrual cycle. The high levels of estrogen produced by the dominant follicle trigger this LH surge, which leads to the rupture of the follicle and release of the egg. The remaining granulosa and theca cells in the follicle then undergo luteinization, forming the corpus luteum and producing progesterone.
