The Testes: The Body’s Reproductive Powerhouses

  1. The testes produce both sperm and the hormone testosterone.
  2. They’re located outside the body to keep sperm at an ideal temperature.
  3. Temperature just a few degrees too high can harm sperm quality.
  4. Each testis contains over 500 tightly coiled sperm-producing tubules.
  5. Testosterone fuels libido, muscle growth, and energy.
  6. The scrotum adjusts position to regulate temperature naturally.
  7. Regular activity and healthy nutrition support testicular health.
  8. The testes begin functioning at puberty and remain active for decades.
  9. Damage or infection can temporarily lower sperm production.
  10. They are small in size but essential for human continuation.
