**Atresia** in the context of the ovary refers to:
AImplantation of embryo in the fundus
BLarge-scale degeneration of primordial / developing ovarian follicles
CFusion of male and female pronuclei
DRelease of the secondary oocyte at ovulation
Answer & Solution
Correct answer: B. Large-scale degeneration of primordial / developing ovarian follicles
Atresia = degeneration. Most primordial follicles never mature: ~2 million at birth → ~40,000 at puberty, the rest lost to atresia. In every cycle, ~6–12 secondary follicles begin to develop but only one becomes a Graafian follicle — the others undergo atresia.
