gonadotrophic hormones

PITUITARY GLAND hormones that stimulate the testicles and the ovaries to produce sperms (spermatozoa), eggs (ova) and sex hormones. Follicle stimulating hormone promotes the growth and development of the eggs ova and sperms, and luteinizing hormone prompts the production of sex hormones. Gonadotrophic hormones are used as drugs to treat infertility, delayed puberty and underdevelopment of the gonads.

gonadotrophin

or

gonadotrophic hormones

hormones secreted by the anterior lobe of the PITUITARY GLAND and in some mammals, once pregnancy is under way, by the PLACENTA. FSH and LH are produced by all TETRAPODS though FSH appears to be absent in fish. LTH (Luteotrophin) is present in rats and maintains the CORPUS LUTEUM though it is absent in other mammals. Prolactin is present in some vertebrates and controls milk production (LTH is a form of prolactin). Pituitary output is controlled by the hypothalamus. Gonadotrophins influence other glands connected with reproduction, controlling the activity of the gonads, the onset of sexual maturity, OESTROUS CYCLES, breeding rhythms and LACTATION. See also HCG.
