  2. Scrotum - Wikipedia

    en.wikipedia.org/wiki/Scrotum

    The scrotum regulates the temperature of the testicles and maintains it at 35 degrees Celsius (95 degrees Fahrenheit), i.e. two or three degrees below the body temperature of 37 degrees Celsius (99 degrees Fahrenheit). Higher temperatures affect spermatogenesis. [12]

  3. Dartos fascia - Wikipedia

    en.wikipedia.org/wiki/Dartos_fascia

    In the scrotum, the dartos fascia acts to regulate the temperature of the testicles, which promotes spermatogenesis. It does this by expanding or contracting to wrinkle the scrotal skin. Contraction reduces the surface area available for heat loss, thus reducing heat loss and warming the testicles.

  4. Cremaster muscle - Wikipedia

    en.wikipedia.org/wiki/Cremaster_muscle

    Cremaster is an involuntary muscle, responsible for the cremasteric reflex; a protective and physiologic superficial reflex of the testicles. The reflex raises and lowers the testicles in order to keep them protected. Along with the dartos muscle of the scrotum, it regulates testicular temperature, thus aiding the process of spermatogenesis. [1]

  5. Pampiniform plexus - Wikipedia

    en.wikipedia.org/wiki/Pampiniform_plexus

    In addition to its function in venous return from the testes, the pampiniform plexus also plays a role in the temperature regulation of the testes. It acts as a countercurrent heat exchanger, cooling blood in adjacent arteries. An abnormal enlargement of the pampiniform plexus is a medical condition called varicocele.

  7. Male reproductive system - Wikipedia

    en.wikipedia.org/wiki/Male_reproductive_system

    During times of lower temperatures, the cremaster muscle contracts and pulls the scrotum closer to the body, while the dartos fascia gives it a wrinkled appearance; when the temperature increases, the cremaster and dartos fascia relax to bring down the scrotum away from the body and remove the wrinkles respectively.

  9. Testicle - Wikipedia

    en.wikipedia.org/wiki/Testicle

    Cryptorchidism, or "undescended testicles", is when the testicle does not descend into the scrotum of an infant boy. [30] Testicular enlargement is an unspecific sign of various testicular diseases, and can be defined as a testicular size of more than 5 cm × 3 cm (short axis). [42]
