Question

Follicular atresia is

• A. Degeneration of zygote
• B. Degeneration of ovarian follicles
• C. Degeneration of embryo
• D. Formation of corpus luteum

Answer 1

The correct option is B

Degeneration of ovarian follicles

Atresia is a hormonally controlled apoptotic process. Ovarian follicular atresia is the periodic process in which immature ovarian follicles degenerate and are subsequently re-absorbed during the follicular phase of the menstrual cycle. Typically around 20 follicles mature each month but only a single follicle is ovulated. The rest undergo atresia. That single dominant follicle becomes corpus luteum following ovulation.
