Boxers or Briefs? Keeping Da Boyz Happy, Healthy, and Strong

The scrotum (or scrotal sac), an extension of a guy’s lower abdomen, is a pouch of skin that is rich in nerve endings and blood vessels (keep that in mind, gals, when you’re making love to him—the scrotum needs lovin’, too!).

The scrotum has two separate compartments that house a single testis, or testicle. Each testicle is suspended within the sac by a spermatic ford, which can be felt through the skin.

The spermatic cord consists of the vas deferens (the duct through which mature sperm travel), the cremasteric muscles, nerves, and blood vessels. One spermatic cord is almost always longer than the other, which is why one testicle (most often, the left) hangs lower than the other.

The cremasteric muscles play a huge role in men’s fertility. They ensure and maintain sperm production by moving the testicles closer to the body when it’s cold, and further away from the body when it’s hot—these muscles are the climate control center for the testicles.

If the body temperature is cold, the cremasteric muscles tighten and draw the testicles closer to the body, to keep them warm. When the body is warm, the cremasteric muscles relax to bring the testicles further away from the already warm body.

Elevated scrotal temperature affects a guy’s testicular function and fertility! Several factors can contribute to these elevated temperatures:
  • Fever
  • Hot tub/sauna use
  • Tight underwear
  • Laptop computers

Wait, what? Laptop computers?!?

New research has determined that men’s use of a laptop computer in the “laptop” position is linked to significant elevated scrotal temperatures (I know, I know….who participates in studies like this?). Scrotal temperatures increase because of the heat from the laptop computer and because of the sitting position necessary to balance the laptop—the position traps the scrotum tightly between the thighs.

For your best fertility and sexual response, keep da boyz happy: Keep ‘em cozy, but not too cozy!

What do you think of the research about laptop computers? Have you ever linked using your laptop to testicular health?!

    What does more damage to the scrotum: Colder or warmer temps?

  2. Dr. Kelly Welch says:

    Josh—Warmer, definitely damages sperm production than colder temps do. The body seems to do a great job providing more warmth to cold testicles by drawing them closer to the body (and, layers of clothing also help to keep them warmer).

    The ideal temperature in the scrotal sac is about 4 degrees lower than the normal body temperature. It's easier for the body to warm the testicles than it is to cool them off.
