June 28, 2018

S.N	Hormones	Functions	Source
Male
1.	Follicle stimulating hormone (FSH)	Increases testosterone production. Aids sperm maturation.	Pituitary gland controlled by hypothalamus.
2.	Gonadotropin releasing hormone (GnRH)	Controls pituitary secretion.	Hypothalamus.
3.	Inhibin	Inhibits FSH secretion.	Sustentacular (sertoli cells) in testes.
4.	Luteinizing hormone (LH)	Stimulates testosterone secretion.	Pituitary gland controlled by hypothalamus.
5.	Testosterone	Increases sperm production. Stimulates development of male primary and secondary sex characteristics. Inhibits LH secretion.	Interstitial endocrinocytes (Leydig cells) in testes (controlled by LH).
Female
1.	Estrogen	Stimulates thickening of uterine walls. Stimulates maturation of oocytes. Stimulates development of female sex characteristics. Inhibits FSH secretion. Increases LH secretion.	Ovarian follicle, corpus luteum (controlled by FSH)
2.	FSH	Causes immature oocyte and follicle to develop. Increases estrogen secretion. Stimulates new gamete formation and development of uterine wall after menstruation.	Pituitary gland (controlled by hypothalamus).
3.	GnRH	Controls pituitary secretion.	Hypothalamus.
4.	hCG (human chorionic gonadotropin)	Prevents corpus luteum from disintegrating. Stimulates estrogen and progesterone secretion from corpus luteum.	Embryonic membranes, placenta.
5.	Luteinizing hormone (LH)	Stimulates further development of oocytes and follicles. Stimulates ovulation. Increases progesterone secretion. Aids development of corpus luteum.	Pituitary gland controlled by hypothalamus.
6.	Oxytocin	Stimulates uterine contractions during labor. Induce mammary glands to eject milk after childbirth.	Pituitary gland controlled by hypothalamus.
7.	Progesterone	Stimulates thickening of uterine wall. Stimulates formation of mammary ducts.	Corpus luteum controlled by LH.
8.	Prolactin	Promotes milk production by mammary glands after childbirth.	Pituitary gland controlled by hypothalamus.
