Pituitary gonadotropins are essential for normal reproductive function. LH and FSH exert their effects by acting on G protein-coupled receptors. Pituitary LH and placental hCG share the same receptor (LHCGR). Homozygous or compound heterozygous inactivating mutations of LHCGR are associated with a phenotypic spectrum from female or ambiguous external ...

PURPOSE Because of the accompanying increase in estrogen levels, safety of performing in vitro fertilization (IVF) in women with breast cancer is unknown. Our goal was to determine the effect of controlled ovarian stimulation (COS) using a combination of

The gonadotropins, follicle-stimulating hormone (FSH) and luteinizing hormone (LH), are glycoproteins produced by gonadotrope cells of the anterior pituitary gland. The two hormones act on somatic cells of the gonads in both males and females to regulate fundamental aspects of reproductive physiology, including gametogenesis and steroidogenesis.

Cochrane Database of Systematic Reviews, 2012
BACKGROUND Gonadotropins are the most commonly used medication for controlled ovarian stimulation in in vitro fertilization (IVF). However, they are expensive, invasive and are associated with risk of ovarian hyperstimulation syndrome (OHSS). With recent

Molecular biology of the pituitary gonadotropins.
Endocrine reviews, 1990Introduction THE pituitary gonadotropins, LH and FSH, play a central role in the mammalian reproductive process. Synthesized in the gonadotropes of the pituitary, the gonadotropins bind to receptors in the gonads leading to effects on steroidogenesis and

Present and future of recombinant gonadotropins in reproductive medicine.
Current Pharmaceutical Biotechnology, 2012Pharmacological ovarian stimulation has a major role in reproductive medicine and has been used in anovulatory patients and in the induction of multifollicular development required for the procedures of assisted reproductive techniques (ART).

Mutations of gonadotropin and gonadotropin receptor genes: the clinical spectrum
Current Opinion in Endocrinology & Diabetes, 2001Mutational analysis of the gonadotropin and gonadotropin receptor genes is an exciting and continuously developing field. Much has been learned from the first mutants identified in patients with clear and expected phenotypes: infertility or extreme precocious puberty in boys.

Pituitary gonadotropins and autoimmunity
Molecular and Cellular Endocrinology, 2014Autoimmune disease occurs when the body produces an inappropriate immune response against its own tissues producing antibodies, called autoantibodies, reacting to specific antigens. Studies regarding the presence of an autoimmune process specifically involving gonadotropins date from over than 20 years ago, when antibodies to gonadotropic-secreting ...

Properties of common carp gonadotropin I and gonadotropin II
General and Comparative Endocrinology, 1992Two gonadotropins, GtH I and GtH II, were extracted with 35% ethanol-10% ammonium acetate, pH 6.1, from female common carp pituitary glands and purified by ion-exchange chromatography on a DE-52 column followed by gel filtration on a Sephadex G-75 column.

The Gonadotropin Response of Men with Varicoceles to Gonadotropin-Releasing Hormone
Fertility and Sterility, 1980The serum gonadotropin and testosterone responses to 100 micrograms of intravenously administered gonadotropin-releasing hormone (GnRH) were studied, over 180 minutes, in four groups of men: severely oligospermic men with varicoceles and sperm densities less than 10 million/ml, men with varicoceles and sperm densities greater than 10 million/ml ...
