MSH: Hormones that stimulate gonadal functions such as GAMETOGENESIS and sex steroid hormone production in the OVARY and the TESTIS. Major gonadotropins are glycoproteins produced primarily by the adenohypophysis (GONADOTROPINS, PITUITARY) and the placenta (CHORIONIC GONADOTROPIN). In some species, pituitary PROLACTIN and PLACENTAL LACTOGEN exert some luteotropic activities.,CSP: any pituitary or placental hormone that stimulates the gonads; major gonadotropins are glycoproteins produced primarily by the adenohypophysis or the placenta.,NCI: Heterodimeric glycoprotein Gonadotropin consists of alpha (common)/beta (unique) protein subunits. The alpha subunit is present in other heterodimeric glycoprotein hormones. The beta subunit confers biological specificity and stimulates ovarian synthesis of steroids (progesterone) to maintain pregnancy.
