LH and FSH are collectively called

Trophe = nourishment. Most of the tropic hormones are secreted by anterior lobe of pituitary. Gonadotropins orgonadotropic hormones are those which stimulate the gonads (testes and ovaries),FSH (Follicle Stimulating Hormone) stimulates growth ofovarian follicles and the secretion ofoestrogens in thefemale andspermatogenesis (formation of sperms) in themale . Luteinizing Hormone(LH) stimulatescorpus luteum of the ovary to secreteprogesterone in the females. In male, it activates theLeydig's (interstitial)cells of the testis to secreteandrogens. Somatotropins or somatotropic hormone orgrowth hormone stimulates growth directly and in conjugation with other hormones the target cells of these hormones are various body cells which undergo growth.Luteotropic hormones stimulates the corpus luteum of the ovary to secrete progesterone hormone. It is also called Prolactin Hormone (PRL) orMammotropin Hormone (MTH) because its main physiological effect is to activate growth of breast during pregnancy and secretion of mammary glands after child birth.Oxytocin (OT; pitocin) is secreted by posterior lobe of pituitary. It promotes contraction of the uterine muscles and myoepithelial cells of the lactating breast, ejecting the milk after child birth. Oxytocin is calledbirth hormone andmilk ejecting hormone.
