Definition for Gonadotropin
From Biology Forums Dictionary
Gonadotropins (or glycoprotein hormones) are protein hormones secreted by gonadotrope cells of the pituitary gland of vertebrates. This is a family of proteins, which include the mammalian hormones follitropin (FSH), lutropin (LH), placental chorionic gonadotropins hCG and eCG and chorionic gonadotropin (CG), as well as at least two forms of fish gonadotropins. These hormones are central to the complex endocrine system that regulates normal growth, sexual development, and reproductive function. The hormones LH and FSH are secreted by the anterior pituitary gland, while hCG and eCG are secreted by the placenta. Gonadotropin is sometimes abbreviated Gn. The British spelling is gonadotrophin.
