Gonadotropin-Releasing Hormone

Gonadotropin-releasing hormone (GnRH) is a peptide hormone responsible for the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the anterior pituitary gland. These hormones are essential for the regulation of the reproductive system in both males and females.

Function

The primary function of GnRH is to stimulate the production and release of FSH and LH from the pituitary gland. FSH and LH play crucial roles in the regulation of the menstrual cycle in females and the production of sperm and testosterone in males.

Regulation

GnRH release is controlled by negative feedback mechanisms involving sex steroids (estrogen and testosterone) and inhibin. In females, estrogen and inhibin provide negative feedback to regulate the release of GnRH, FSH, and LH. In males, testosterone and inhibin play a similar role in regulating the release of GnRH, FSH, and LH.

Clinical Significance

Disorders in the regulation of GnRH can lead to reproductive health issues such as infertility, delayed puberty, and irregular menstrual cycles. Additionally, GnRH agonists and antagonists are used in the treatment of conditions such as endometriosis, uterine fibroids, and prostate cancer.
