Oxytocin

A. Oxytocin is secreted from the posterior pituitary and helps in the contraction of uterus during childbirth and also stimulates release of milk from mammary glands i.e. lactation.

B. Follicle stimulating hormone (FSH) is secreted from the anterior part of pituitary gland. It stimulates the growth of ovarian follicles in females and seminiferous tubules in males.

C. Luteinizing hormone or LH stimulates growth of ovarian follicles in females. In males this hormone is called interstitial cell stimulating hormone or ICSH and affects the Leydig cells of testes.

D. Prolactin, also known as lactogenic hormone is produced by the pituitary gland. This hormones stimulates the production of milk in mammary glands during pregnancy. It is secreted in males also but remains non-functional.
