What is a Graafian Follicle? What is a Graafian Follicle? Ovarian follicles are the essential units of female reproductive biology, each of which is packed with roughly spherical aggregations of cells found in the ovary. A Graafian follicle, or ovarian follicle, is present inside an ovary and is a minute cyst within which an egg, or ovum, develops. A Graafian follicle is a follicle that ruptures and releases its ovum when stimulated. Generally, women are born with many undeveloped follicles, each containing an immature ovum.

RIXIMKA DUMARKA Granulosa cells or follicular cells are cells that surround the oocyte within the follicle; their numbers increase directly in response to heightened levels of circulating gonadotropins or decrease in response to testosterone.nce a month, one of the ovaries releases a mature egg (ovum), known as an oocyte. A follicle is an anatomical structure in which the primary oocyte develops. The nucleus of such an oocyte is called a germinal vesicle (see picture).

Alternative names for follicle stimulating hormone Follicle stimulating hormone is one of the gonadotrophic hormones, the other being luteinising hormone. Both are released by the pituitary gland into the bloodstream. Follicle stimulating hormone is one of the hormones essential to pubertal development and the function of women’s ovaries and men’s testes.owever as the follicle matures, and more and more oestrogen is produced from the follicles, it simulates a surge in luteinising hormone and follicle stimulating hormone which stimulates the release of an egg from a mature follicle – ovulation.

graafian follicle As the follicle matures, it moves to the surface of the ovary and forms a projection. When fully mature, the graafian follicle breaks open and releases the ovum, which passes into the uterine tubes. This release of the ovum is called ovulation. The released ovum travels down the tube to the uterus.

Follicle Growth and Development The mechanisms regulating follicle growth and development are under the control of changing concentrations of ligands (i.e. hormones and growth factors). At the endocrine level, folliculogenesis is regulated by a central nervous system, anterior pituitary, and ovary cascade mechanism.

- Follicle-stimulating hormone (FSH) is a glycoprotein hormone found in humans and other animals. It is synthesized and secreted by gonadotropes of the anterior pituitary gland, and regulates the development, growth, pubertal maturation, and reproductive processes of the body. FSH and luteinizing hormone (LH) act synergistically in reproduction.
