Female Reproductive function and cycles
Hormones of the female reproductive cycle: Anterior pituitary gland: Follicle stimulating hormone (FSH): Stimulates growth of ovarian follicles, and estrogen.
Pituitary Gland FSH Primordial follicles Growing follicles LH.
C) The Menstrual Cycle The female menstrual cycle takes an average of 28 days. (Variation is common). The cycle occurs in four phases if no fertilization.

Presentation transcript:

Hormones synchronize ovarian and menstrual cycles FSH – (follicle stimulating hormone) from anterior pituitary stimulates growth of the follicle LH – (luteinizing hormone) peaks about day 14 causes ovulation stimulates completion of meiosis I promotes secretion of more estrogen and progesterone ovulation test Estrogen – released from maturing follicle thickens endometrium inhibits more FSH.LH release Progesterone – released from corpus luteum thick endometrium Ovarian Cycle Menstrual Cycle

Hormones cont….. HCG – (Human Chorionic Gonadotropin) When estrogen is low – pituitary releases FSH/LH When estrogen is high – inhibit release of FSH/LH HCG – (Human Chorionic Gonadotropin) present if the embryo implants in the endometrium Maintains corpus luteum and continues to secrete progesterone and estrogen to keep endometrium intact pregnancy test

Secondary sex characteristics results from hormones Male Deeper voice Beard and more body hair Chest broadens Larger muscles Langer growth stage Female Enlargement of breasts and reproductive organs Wider hips Hair in armpits and pubic area Menstruation Fat deposits under skin
