GENERAL HISTOLOGY

Detailed explanation-1: -GnRH stimulates FSH release. 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 .

Detailed explanation-2: -Follicle stimulating hormone (FSH) is produced by the pituitary gland in the brain. It is an important hormone for normal functioning of the reproductive system in men and women.

Detailed explanation-3: -The ovulatory phase begins with a surge in luteinizing hormone and follicle-stimulating hormone levels. Luteinizing hormone stimulates egg release (ovulation), which usually occurs 16 to 32 hours after the surge begins. The estrogen level decreases during the surge, and the progesterone level starts to increase.

Detailed explanation-4: -In women, FSH helps control the menstrual cycle and stimulates the growth of eggs in the ovaries. FSH levels in women change throughout the menstrual cycle, with the highest levels happening just before an egg is released by the ovary. This is known as ovulation. In men, FSH helps control the production of sperm.

Detailed explanation-5: -FSH is produced by the pituitary gland, a small pea-sized gland situated at the base of the brain. To produce FSH, the pituitary gland must receive messages from the hypothalamus part of the brain. FSH then stimulates the ovaries or the testes to produce and mature eggs or sperm.
