    • deposits sperm into the vagina
    • consists of glans and body
  5. functions of the testes
    • make sperm
    • secrete androgens
    • testosterone made in the Leydig cells of the testes
  6. Role of FSH and LH in the testes

  10. vas deferens
    carries the mature sperm into the body to the ejaculatory ducts
  11. Ejaculatory Duct
    Each vas deferens joins the duct from the adjacent seminal vesicle (one of the accessory glands) to form a short (2cm) ejaculatory duct. Each ejaculatory duct passes through the prostate gland and empties into the urethra.
  12. seminal plasma
    • secretions from the accessory glands
    • nourish sperm
    • protect sperm from the acidic vaginal environment
    • enhances motility

    Protects the symphasis pubis
  15. Labia Majora
    2 folds of fatty tissue on each side of the vagina
  16. Labia Minora
    • 2 thin, soft folds of erectile tissue inside of the labia majora
    • Produces bactericidal secretions, lubricates and protect the vulva

    • aka obstetrical perineum
    • lacerations often occur during childbirth
  18. Vaginal Vestibule

    • 2 sets make up part of the female pelvis
    • made up of ilium, pubis and ischium
  21. femal pelvis types
    • gynecoid: best for vaginal birth, round
    • android: wedge-shaped, typical of males
    • anthrapoid: oval shaped
    • platypelloid: transverse oval, pt usually requires c-section
