Gonadotropins are any hormones that are released from the anterior pituitary to stimulate the gonads, or sex glands, to carry out their reproductive functions. The gonadotropin-releasing hormone (GnRH) is therefore fundamental for mammalian reproduction. In a healthy reproductive system GnRH is produced by the brain in pulses. Reports suggest that at least 25% of ovarian disorders are due to dysfunction of the brain mechanism controlling the release of gonadotropins, which is a kind of reproductive disorder associated with the hypothalamus. ....
