Tight Underwear Prevent Muscle Growth?

Hi Davey,

There are a lot of people that say that tight underwear lowers our sperm count and testosterone levels, thereby preventing muscle gain. Is it true?

Hey Frank,

I’m so glad you asked this question!

First things first, it’s common knowledge that testosterone aids in muscle growth. The more testosterone you have, the more muscle you’re likely to build through your training. And, of course, this has been proven time and time again through the use of anabolic steroids, which – though dangerous – mimic testosterone and result in muscle growth.

If you do a Google search, you’ll see countless websites warning of the link between tight underwear and reduced testosterone and sperm counts. But rarely do they cite any research to back up their claims. I’m interested in science – not rumors.

These rumors note that the testes hang from the body for a reason; they need to be cooler to function properly. By wearing tight underwear, we hold the testes close to the body – thus, potentially raising the internal testicular temperature and decreasing functionality.

Not surprisingly, researchers have studied the link. In fact, back in 1998, Munkelwitz and Gilbert from the University of New York published a study about underwear and fertility titled, “Are Boxer Shorts Really Better?” After studying a number of volunteers, the researchers concluded that there is “no difference in scrotal temperature depending on underwear type” and that it was “unlikely that underwear type has a significant effect on male fertility.” Since testosterone influences sperm count, the research suggests that its levels aren’t influenced by tight underwear. Since then, other studies have come to similar conclusions.

Reduced testosterone levels can be caused by any number of conditions or circumstances, including:

  • Testicular damage
  • Post-puberty mumps
  • Radiation or chemotherapy
  • Testicular tumors
  • HIV/AIDs and other viral infections
  • Genetic conditions

Whether you’re in favor of boxers or briefs, know that it won’t affect your testosterone levels or your ability to build muscle. What you eat and how you work out, on the other hand, will greatly impact your results.

Love,
