 (gō-năd′ə-trō′pĭn, -trŏp′ĭn) also go·nad·o·tro·phin (-trō′fĭn, -trō′pĭn)
A hormone that stimulates the growth and activity of the gonads, especially any of several pituitary hormones that stimulate the function of the ovaries and testes.


(ˌɡɒnədəʊˈtrəʊfɪn) or


(Biochemistry) any of several glycoprotein hormones secreted by the pituitary gland and placenta that stimulate the gonads and control reproductive activity. See chorionic gonadotrophin, follicle-stimulating hormone, luteinizing hormone, prolactin

follicle-stimulating hormone, FSH - a gonadotropic hormone that is secreted by the anterior pituitary and stimulates growth of Graafian follicles in female mammals, and activates the cells in male mammals that form sperm

It was followed by stimulation of the ovary using recombinant follicle-stimulating hormone (rFSH) (Gonal-F; Merk-Sereno, Geneva, Switzerland) or human menopausal gonadotrophin (Menopur; Ferring Pharmaceuticals, Germany), and the follicular growth was monitored by using a transvaginal sonography with an SSD-1000 machine (Aloka, Tokyo, Japan).

Leptin increases insulin sensitivity by influencing insulin secretion, glucose utilization, glycogen synthesis and fatty acid metabolism, regulates gonadotrophin releasing hormone secretion from the hypothalamus and activates the sympathetic nervous system (16, 12).
The physiological mechanism underlying the photo-stimulation is that an increase in photoperiod elevates the rate of secretion of gonadotrophin-releasing hormone I (GnRH-I), leading to augmented gonadotrophin secretion, and hence gonadal maturation such as luteinizing hormone (LH) and follicule hormone (FSH) which in turn induce gonad growth and steroid hormone production [25].
As the tumour markers (CA-125, beta-human chorionic gonadotrophin and alpha-fetoprotein) were within the normal range, a working diagnosis of growing teratoma syndrome (GTS) of the ovary was made.
Superovulation is a term used to describe the administration of exogenous gonadotrophin to induce the growth and maturation of many ovarian follicles to increase the number of mature ovum for fertilization (Baldassarre et al.
Supplementation of gonadotrophin and steroids in the maturation medium will increase the oocytes potential for fertilization and embryonic development so conditions were similar to those in vivo [2].
