MEDICAL PHYSIOLOGY

Detailed explanation-1: -The hypothalamus produces GnRH, and it is released into the hypophyseal portal circulation to act on G-protein-coupled receptors at gonadotropic cells of the anterior pituitary . Those gonadotropic cells produce FSH and luteinizing hormone (LH) and release them into the peripheral circulation.

Detailed explanation-2: -Follicle-stimulating hormone (FSH): This hormone stimulates the testes to produce sperm and stimulates the ovaries to produce eggs and estrogen. Luteinizing hormone (LH): This hormone stimulates ovulation in women and testosterone production in men.

Detailed explanation-3: -Follicle stimulating hormone is produced by the pituitary gland. It regulates the functions of both the ovaries and testes. Lack or low levels of it can cause subfertility in both men and women.

Detailed explanation-4: -Gonadotropin-releasing hormone causes the pituitary gland in the brain to make and secrete the hormones luteinizing hormone (LH) and follicle-stimulating hormone (FSH). In men, these hormones cause the testicles to make testosterone. In women, they cause the ovaries to make estrogen and progesterone.
