GONADOTROPIC HORMONE

Definition

Hormone that stimulates or maintains the elaboration and functioning of the gonads. In vertebrates gonadotropins are peptide hormones produced in the pituitary gland under the control of gonadotropin releasing factor; cf. human chorionic gonadotropin. They stimulate the secretion of steroid sex hormones (e.g. testosterone, oestrogens). Pituitary extracts (often from different species) are administered to fish to produce fry outside of the normal breeding period. Syn. Gonadotrophic hormone, gonadotropin.
