| gonadotrophins | <endocrinology> Group of glycoprotein hormones from the anterior lobe of the pituitary gland. They stimulate growth of the gonads and the secretion of sex hormones. Examples: follicle-stimulating hormone, luteinising hormone, chorionic gonadotrophin. (18 Nov 1997) |

| gonadotropic | 1. Descriptive of or relating to the actions of a gonadotropin. 2. Promoting the growth and/or function of the gonads. Synonym: gonadotrophic. Origin: Gonado-+ G. Trope, a turning (05 Mar 2000) |
| gonadotropic hormone | <endocrinology, hormone> A hormone capable of promoting gonadal growth and function. The effects are usually limited to discrete functions or histological components of a gonad, such as stimulation of follicular growth or of androgen formation. Most gonadotrophin's exert their effects in both sexes, although the effect of a given gonadotrophin will differ in males and females. Synonym: gonadotropin, gonadotropic hormone. Origin: for gonadotrophin, fr. Gonad + G. Trophe, nourishment (12 Sep 2002) |

| gonadotropin, human chorionic | A human hormone made by chorionic cells (in the foetal part of the placenta), hCG is directed at the gonads and stimulates them. HCG becomes detectable (by immunologic means) within days of fertilization and forms the foundation of the common pregnancy tests. The level of hCG in maternal serum also enters as one component in the double and the triple screens used during pregnancy to assign risks of Down syndrome and other foetal disorders. (12 Dec 1998) |
| gonadotropin-producing adenoma | <tumour> A rare type of pituitary adenoma that produces FSH and LH; its cells can be identified only by immunochemical techniques. (05 Mar 2000) |
| gonadotropin-releasing factor | <hormone> The peptide hormone that control reproductive function. It produced and released by the hypothalamus and controls the production and release of gonadotrophins from the pituitary gland. It causes the production of luteinising hormone and follicle-stimulating hormone. Synonym: gonadotropin-releasing factor, gonadotropin-releasing hormone, luteinizing hormone/follicle-stimulating hormone-releasing factor, gonadoliberin. Origin: Gonad + L. Libero, to free, + -in (19 Sep 2002) |

| gonadotropins, equine | Polypeptide hormones secreted in pregnant mares at the junction of the placenta and endometrial cups. Preparations of this taken from the blood serum of pregnant mares have been used in the treatment of infertility, pituitary dwarfism, cryptorchidism, and other conditions in both human males and females. (12 Dec 1998) |
| gonads | <anatomy> The gamete-producing glands, ovary or testis. (12 Dec 1998) |
| gonaduct | Synonym: seminal duct, uterine tube. Origin: Gonado-+ duct (05 Mar 2000) |
