follicule emptius

Detailed explanation-1: -The egg bursts from the follicle, leaving behind an empty shell of cells. Those cells go through a transformation after the egg is released, collapsing in on themselves and changing the hormones they secrete. This collapsed follicle is what becomes the corpus luteum.
Detailed explanation-2: -The corpus luteum secretes estrogens and progesterone. The latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. If the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.
Detailed explanation-3: -b) Luteinising hormone (LH) converts the empty follicle into the corpus luteum and stimulates it to produce progesterone.
