It is a medicine used in assisted reproduction. It is chemically composed by a GnRH analogue and is used to stimulate the ovarian cycle in a controlled manner.
Gonadotropins are hormones secreted by the pituitary gland after the stimulation of GnRH pulses. Gonadotropins are produced by men and women and they regulate the reproductive cycle in both cases, although they do not have the same levels of gonadotropins and the actions regulated are different in each case. There are three types of gonadotropic hormones: FSH, LH, and hCG.
