Granulosa cells developing follicles secrete
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. WebGraafian follicle: As the follicle continues to develop, the thecal cells multiply forming several layers on the outside of the follicle. Additionally, the granulosa cells continue to increase in number and begin to secrete fluid (follicular fluid) resulting in the formation of fluid filled spaces among the granulosa cells.
