| gonadectomy | Excision of ovary or testis. Origin: Gonado-+ G. Ektome, excision (05 Mar 2000) |
| gonado- | Gonad- The gonads. Origin: G. Gone, seed (05 Mar 2000) |
| gonadoblastoma | <oncology, tumour> A cancerous neoplasm, or abnormal growth (a type of dysgerminoma), in the ovary. It includes germ line cells and other components usually found within gonads. (09 Oct 1997) |
| gonadocrins | Peptides that stimulate release of both follicle-stimulating hormone and luteinizing hormone from the pituitary; found in ovarian follicular fluid in rats. Origin: Gonad + G. Krino, to secrete (05 Mar 2000) |
| gonadoliberin | <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) |
| gonadopathy | Disease affecting the gonads. Origin: Gonado-+ G. Pathos, suffering (05 Mar 2000) |
| gonadorelin | <chemical> A decapeptide hormone released by the hypothalamus that stimulates the secretion of follicle-stimulating hormone (fsh) and luteinizing hormone (lh) from the pituitary gland. Chemical name: Luteinizing hormone-releasing factor (pig) (12 Dec 1998) |
| gonadorelin hydrochloride | C55H75N17O13-xHCl;a gonadotropin-releasing hormone obtained from sheep, pigs, or other animals and used to evaluate the functional capacity of the gonadotrophs of the anterior pituitary. Origin: Gonadotropin-releasing + -in (05 Mar 2000) |
| gonadotroph | An endocrine cell of the adenohypophysis that affects certain cells of the ovary or testis. (05 Mar 2000) |
| gonadotrophic | <endocrinology> Stimulating the gonads, applied to hormones of the anterior pituitary which influence the gonads. Origin: Gr. Tropos = a turning (18 Nov 1997) |
| gonadotrophic cycle | One complete round of ovarian development in the insect vector from the time when the blood meal is taken to the time when the fully developed eggs are laid. (05 Mar 2000) |
| gonadotrophin | <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) |
| gonadotrophin-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) |
| gonadotrophin-releasing hormone | <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.
