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.
The ovarian hyperstimulation syndrome can be due to several causes. Sometimes it occurs naturally, but it can also occur because of the use of hormones in assisted reproductive techniques.
This syndrome occurs in women when an abnormally exaggerated ovarian response occurs. It may occur naturally or as a consequence of hormone administration during assisted reproductive treatments.
