Answer

SOLUTION:

• At the pituitary, Gonadotropin Releasing Hormone (GnRH) stimulates the synthesis and secretion of the gonadotropins, follicle-stimulating hormone (FSH), and luteinizing hormone (LH).
• These processes are controlled by the size and frequency of GnRH pulses, as well as by feedback from androgens and estrogens.
• GnRH is a hormone produced in the hypothalamus region of the brain. GnRH moves through the bloodstream to the pituitary gland.
• There, it binds to certain receptors. Those receptors signal the pituitary gland to create two more hormones which are LH and FSH.
• High levels of estrogen and progesterone give negative feedback to hypothalamus for the release of GnRH resulting in inhibition of the gonadotropin release.
