Pete Hegseth's Pentagon testosterone screening mandate has men asking whether their levels are normal. Here's what doctors say about diagnosis.

There’s a myth that masturbating can lower your testosterone, but it’s not true. However, whether sex decreases or increases testosterone levels really isn’t known, says James Hotaling, MD, a urologist and male fertility expert at the University of Utah in Salt Lake City.

Make sure the number on a testosterone check opens a real evaluation of health instead of becoming a shortcut to a prescription, Dr. Jamin Brahmbhatt advises.

Defense Secretary Pete Hegseth says he's rolling out a new screening program for “testosterone deficiency” among troops.
