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.
LH is released from the pituitary gland along with FSH in response to GnRH release into the hypophyseal portal system. [4] Pulsatile GnRH release causes pulsatile LH and FSH release to occur, which modulates and maintains appropriate levels of bioavailable gonadal hormone—testosterone in males and estradiol in females—subject to the requirements of a superior feedback loop.

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 ...
Secretion is stimulated by the thyroid-stimulating hormone, secreted by the anterior pituitary. When thyroid levels are high, there is negative feedback that decreases the amount of Thyroid-stimulating hormone secreted. Most T4 is converted to T3 (a more active form) in the target tissues.
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 ...

The follicle-stimulating hormone receptor or FSH receptor (FSHR) is a transmembrane receptor that interacts with the follicle-stimulating hormone (FSH) and represents a G protein-coupled receptor (GPCR). Its activation is necessary for the hormonal functioning of FSH. FSHRs are found in the ovary, testis, and uterus.
