A follicle that has two layers of follicular cells is called a primary follicle. These cells continue to hypertrophy and proliferate to form many layers surrounding the oocyte. Eventually these cells become known as ‘granulosa’ cells.

WebAnd they start off as primordial follicles. And so what a follicle is- I'll just blow that up for you- It's one primary oocyte, so an egg cell, surrounded by a layer of cells called granulosa cells. And the granulosa cells develop and become more numerous as the follicle matures. Now the granulosa cells also secrete a few hormones. WebFollicle-stimulating hormone (FSH) is a glycoprotein gonadotropin secreted by the anterior pituitary in response to gonadotropin-releasing hormone (GnRH) released by the hypothalamus. The pituitary gland also secretes luteinizing hormone (LH), another gonadotropin. FSH and LH are composed of alpha and beta subunits.
