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]
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.
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]
It works involuntarily. Its role is to bring the testicles down if the body temperature rises or to raise them if the body temperature drops. This process allows it to regulate the temperature of the testicles and to keep it several degrees lower than that of the body in order to enable an ideal spermatogenesis. [17] [18]
Some men have medical conditions that impair testicular testosterone production, such as Klinefelter’s syndrome. This type of testosterone deficiency is known as primary testicular failure or ...
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]
7) Put a cock ring on it. A cock ring—also known as a penis ring—is a band and that goes around the base of your penis (and sometimes your testicles, too), trapping blood flow in your shaft ...
1) Touch your taint. If you haven’t already been introduced, meet your taint—or your perineum, if we’re getting technical.It’s the strip of skin between your balls and your butt, and it ...
