Presentation Transcript

  1. Reproductive System OrgansHormonal Control

  2. Seminal vesicle: fructose, prostaglandins for semen Male Reproductive System Penis: erectile organ Prostate gland: alkaline secretion for semen Urethra: exit tube for semen Bulbourethral gland: mucoid fluid for semen Vas Deferens: sperm transport Epididymis: sperm maturation Scrotum: suspends testes Testis: sperm production

  3. Site of sperm production within testis Contains chromosomes Contains enzymes for digesting through the egg’s protective coat For movement Has mitochondria for energy release Sperm Formation

  4. Gonadotropin Releasing Hormone stimulates Pituitary to release LH, FSH Follicle Stimulating Hormone Luteinizing Hormone Negative feedback to pituitary & hypothalamus Male sex characteristics Hormonal Regulation in Males Negative feedback to pituitary & hypothalamus

  5. Which one produces an alkaline secretion as part of semen? From which one do sperm exit the body? Where are sperm produced? Epididymis Prostate Gland Testis Urethra Vas Deferens Applying Your Knowledge 2 4 3

  6. Fallopian tube: egg transport, site of fertilization Clitoris: erectile organ Ovary: egg production Female Reproductive System Uterus: site of fetal development Vagina: birth canal, exit for menstrual flow, site of sexual intercourse

  7. immature egg Ovarian Cycle 1. Primary follicles containoocyte and begin producingthe sex hormone estrogen

  8. Stimulates Pituitary to release FSH, LH Follicle Stimulating Hormone: development of follicle, containing egg Luteinizing Hormone: controls ovulation, development of corpus luteum Estrogen: produced in ovary, stimulates thickening and vascularization of uterine lining Progesterone: produced in ovary, stimulates increased thickening of uterine lining Hormonal Regulation in Females Estrogen and Progesterone exert negative feedback on hypothalamus and pituitary Female sex characteristics

  9. Hormone Levels in Ovarian and Uterine Cycles

  10. Fertilization and Implantation Fertilization: Sperm enters egg Implantation: embryo attaches to uterine lining

  11. From Ovulation to Implantation

  12. Which hormone stimulates egg development? Which hormone stimulates sperm development? Which hormone maintains the buildup of the uterine lining? LH FSH Estrogen Progesterone Testosterone Applying Your Knowledge 2 2 4
