Follicle-stimulating hormone (FSH) is a gonadotropin, a glycoprotein polypeptide hormone. [1] FSH is synthesized and secreted by the gonadotropic cells of the anterior pituitary gland [ 2 ] and regulates the development, growth, pubertal maturation , and reproductive processes of the body.
FSH stimulates the secretion of inhibin from the granulosa cells of the ovarian follicles in the ovaries. In turn, inhibin suppresses FSH. Inhibin B reaches a peak in the early- to mid-follicular phase, and a second peak at ovulation. Inhibin A reaches its peak in the mid-luteal phase.
By stimulating GnRH release, kisspeptin indirectly promotes the secretion of LH and FSH from the pituitary gland. Two main populations of kisspeptin neurons have been identified in the hypothalamus: one in the arcuate nucleus (ARC) and another in the anteroventral periventricular nucleus (AVPV) in rodents, or the preoptic area (POA) in humans.

FSH, luteinizing hormone. thyroid-stimulating hormone, and hCG are all known to affect Sertoli cell development and male reproductive health. FSH is required for Sertoli cell mitogen, which stimulates the expression of various cell markers. [7]
Gonadotropic cells (also known as gonadotropes, gonadotrophs, delta cells, or delta basophils) are endocrine cells in the anterior pituitary that produce gonadotropins.More specifically, gonadotrophs produce and secrete glycoprotein polypeptide hormones, such as the follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which are released due to the positive input of gonadotropin ...
Glycoprotein hormones, alpha polypeptide is a protein that in humans is encoded by the CGA gene. [5]The gonadotropin hormones, human chorionic gonadotropin (hCG), luteinizing hormone (LH), follicle-stimulating hormone (FSH), and thyroid-stimulating hormone (TSH) are heterodimers consisting of alpha and beta subunits (also called chains) that are associated non-covalently.
An earlier name for the same protein was FSH-suppressing protein (FSP). At the time of its initial isolation from follicular fluid , it was found to inhibit the anterior pituitary 's secretion of follicle-stimulating hormone (FSH).
Gonadotropins are glycoprotein hormones secreted by gonadotropic cells of the anterior pituitary of vertebrates. [1] [2] [3] This family includes the mammalian hormones follicle-stimulating hormone (FSH) and luteinizing hormone (LH), the placental/chorionic gonadotropins, human chorionic gonadotropin (hCG) and equine chorionic gonadotropin (eCG), [3] as well as at least two forms of fish ...
