  3. Male Reproductive System 1. Primary Sex Organs (gonads): two testes 2. Secondary Sex Organs: penis, scrotum, system of ducts including epididymis, ductus (vas) deferens, urethra 3. Accessory Glands prostate, seminal vesicles, bulbourethral glands 14-3

  4. Male External Genitalia • Perineum • Scrotum • Testes • Penis 14-4

  5. Testes • 250 Lobules, each containing three or four seminiferous tubules where sperm are being formed. • Epididymis stores sperm until maturity. • Interstitial cells produce androgens, including testosterone. • Supported from abdominal cavity by spermatic cord 14-5

  6. Functions of Testosterone • Stimulates spermatogenesis. • Stimulates development of male secondary sex characteristics. • Stimulates growth burst at puberty. • Stimulates brain to increase sex drive. 14-6

  7. Spermatogenesis • Germ cells (23 pairs of chromosomes = 46 total) in seminiferous tubules • Divide into 2 identical copies called daughter cells (23 pairs of chromosomes) • Divide again into 4 daughter cells (23 chromosomes, not pairs) which mature into spermatozoa 14-7
