Gonadotropins or gonadotrophins are a group of hormones secreted in the pituitary gland or hypophysis.
From the pituitary gland, the different hormones needed by the different endocrine glands of the body are developed, among which are the sex hormones.
Gonadotropins play a fundamental role in human reproduction. These hormones influence a woman's ovulation, stimulating the ovarian cycle and generating an egg that can be fertilized, by which a pregnancy will subsequently develop.
It is also used in men to treat hypogonadotropic hypogonadism, a disorder characterized by low testosterone levels and insufficient LH production.
The drug is also used in the treatment of prepubertal cryptorchidism, a condition in which one or both testicles have failed to descend into the scrotum.
PREGNYL is used by male athletes for its ability to increase endogenous testosterone production, usually during or at the end of a steroid cycle (post cycle) when natural hormone production has been disrupted.
