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.
hormones that stimulate the ovary, FSH and LH. They are normally secreted by the pituitary gland in the brain. They may be also contained in drugs that are injected in women as part of infertility therapy.
A generic term referring to both urinary-derived FSH and/or LH product (known as menotropins) and recombinant DNA-derived FSH and LH, as well as the naturally occurring hormones LH and FSH, which are released by the pituitary gland to stimulate the testicles in the man and the ovaries in the woman.
Hormones produced by and released from the pituitary to control the function of the gonad. There are two gonadotropins: the follicle-stimulating hormone (FSH) and the luetinizing hormone (LH) These hormones are completely different in chemical composition from the steroids.
literally, "gonad stimulators". The most important gonadotropins are follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which are produced by the pituitary gland. In women, these gonadotropins help regulate ovulation. In men, they regulate sperm and testosterone production.
Fertility drugs that provide the patient with FSH and LH, or FSH alone. Gonadotropins are highly potent fertility drugs and are not usually used unless clomiphene citrate has proven ineffective. Patients receiving gonadotropins (such as PergonalÂ®, Gonal F, and Profasi) must be monitored by their physicians.
The category of hormones capable of stimulating the ovary or the testicle to ultimately result in egg or sperm maturation and release.Â FSH, LH, and hCG are hormones, and all are used at some time during the ovarian stimulation phase of IVF.
Gonadotropins are the hormones FSH and LH that are normally produced by the pituitary to stimulate the ovary. This group medication has various forms: from urinary origin – both FSH and LH (In Bulgaria are registered: Pergonal, Menogon, Metrodin, Humegon) or from recombinant origin – FSH and LH. Careful monitoring with ultrasound and hormone tests is required to prevent overstimulation of the ovary leading to the hyperstimulation syndrome.
