Graafian follicle
Lutein cells are the glandular-epithelial cells forming the outer layer of the corpus luteum. They develop from cells of the Graafian follicle.
When fully mature, the Graafian follicle breaks open and releases the ovum, which passes into the fallopian tubes.

In females, in the ovary FSH stimulates the growth of immature Graafian follicles to maturation. Graafian follicles are the mature follicle. Primary follicles mature to Graafian follicles. As the follicle grows, it releases inhibin, which shuts off the FSH production.

The main one is progesterone, but the corpus luteum also produces estrogen.
FSH stimulates spermatogenesis and development of graafian follicles.LH stimulates secretion of sex hormones,emmits ova and turn graafian follicle into corpus luteum.
When ovulation occurs, the graafian follicle(s) rupture. The oocyte with surrounding cumulus cells (COC's) are expelled into the infundibulum and transported to the site of fertilization. Before and during the rupture of the graafian follicle, blood vessels will rupture too, which causes hemorrhaging. So the structure that is left behind after the oocyte is expelled, is called a corpus hemorrhagicum.
Follicle development occurs in several stages: primordial follicle, primary follicle, secondary follicle, preantral follicle, antral follicle, and mature (Graafian) follicle. Each stage involves specific changes in the follicle and oocyte as they mature towards ovulation.
