74. Testis

Covers the testis as part of the male reproductive system, starting with an overview of the organs and an embryological account of the indifferent stage and testis development. It then describes the testis's position in the scrotum, external and internal structure, coverings, and its arterial, venous, lymphatic and nerve supply, followed by the epididymis, ductus deferens, and the spermatic cord. A table compares the scrotal layers with the abdominal wall layers they correspond to.

MALE REPRODUCTIV System.

- The male reproductive system responsible for the production, storage and delivery of sperm.

Organs :

  1. 1. Testes: The primary male reproductive organs responsible for producing sperm and testosterone.
  2. 2. Epididymis: A coiled tube located on the back of each testicle where sperm mature and are stored.
  3. 3. Vas Deferens: Tubes that carry mature sperm from the epididymis to the urethra during ejaculation.
  4. 4. Seminal Vesicles: Glands that produce a significant portion of semen, providing nutrients and fluid to sperm.
  5. 5. Prostate Gland: Produces a fluid that nourishes and protects sperm, forming part of semen.
  6. 6. Bulbourethral Glands: Also known as Cowper's glands, they secrete a clear fluid that lubricates the urethra and neutralizes acidity in the urethra.
  7. 7. Urethra: A tube that carries urine and semen out of the body through the penis, though not simultaneously.
  8. 8. Penis: The external male reproductive organ that contains the urethra and is involved in sexual intercourse and urination.
  9. 9. Scrotum: A sac of skin and muscle that houses the testes, helping to regulate their temperature for optimal sperm production.
  10. 10. Hypothalamus and Pituitary Gland: Control the production and release of hormones that regulate the functions of the male reproductive system, including testosterone.
