Human Menopausal Gonadotropins are protein hormones secreted by gonadotrope cells of the pituitary gland of vertebrates.Gonadotropin is sometimes abbreviated Gn. The British spelling is gonadotrophin.
Gonadotropin deficiency due to pituitary disease results in hypogonadism, which can lead to infertility. Treatment includes administered gonadotropins, which, therefore, work as fertility medication. Such can either be produced by extraction and purification from urine or be produced by recombinant DNA.
Failure or loss of the gonads usually results in elevated levels of LH and FSH in the blood.
