7.4 MALE REPRODUCTIVE SYSTEM

1. Internal parts of the reproductive system.

1. Testes

  1. The testes are ovoid structures suspended by a spermatic cord in the scrotum.
  2. Structure of the Testes
  3. Each of the testes is made up of 250 lobules separated by connective tissue; each lobule holds one to four highly coiled seminiferous tubules.
  4. Seminiferous tubules are lined with stratified epithelium that gives rise to sperm cells.
  5. Interstitial cells lie between the seminiferous tubules and produce the male hormones.
  6. Channels leading from the seminiferous tubules carry sperm to the epididymis and vas deferens.
  7. The accessory organs of the male reproductive tract include the epididymides, vasa deferentia, ejaculatory ducts, urethra, seminal vesicles, prostate gland, and bulbourethral glands.
