Folliculogenesis

Order of changes in ovary.1 - Menstruation2 - Developing follicle3 - Mature follicle4 - Ovulation5 - Corpus luteum6 - Deterioration of corpus luteum
(a) The maturation of a follicle is shown in a clockwise direction proceeding from the primordial follicles. FSH stimulates the growth of a tertiary follicle, and LH stimulates the production of estrogen by granulosa and theca cells. Once the follicle is mature, it ruptures and releases the oocyte. Cells remaining in the follicle then develop into the corpus luteum. (b) In this electron micrograph of a secondary follicle, the oocyte, theca cells (thecae folliculi), and developing antrum are clearly visible. Electron microscopy images
Although the process is similar in many animals, this article will deal exclusively with human folliculogenesis.

In biology, folliculogenesis is the maturation of the ovarian follicle, a densely packed shell of somatic cells that contains an immature oocyte. Folliculogenesis describes the progression of a number of small primordial follicles into large preovulatory follicles that enter the menstrual cycle.
