Appearance aside, boxers may be the optimal underwear for men aiming to be fathers.
Men who wear looser-fit boxer shorts have higher sperm concentration than men squeezed into tight underwear, a new study published Wednesday in the journal Human Reproduction found. Sperm concentration, which is the number of sperm per milliliter of semen, is one of a few standard metrics of male fertility.
However, men who preferred bikinis, better known as briefs, and other tight-fitting underwear had higher levels of follicle-stimulating hormone compared to the men in boxers. Because this hormone stimulates sperm production, the researchers speculate these higher levels, which push the testicles to work harder at producing sperm, may be the bodys way of compensating for lower sperm concentration.
Whether underwear choice affects sperm production has been a topic of research for several years, said Lidia Mínguez-Alarcón, lead author of the new study and a research scientist at Harvards T.H. Chan School of Public Health. But this study is the first to investigate whether a mans selection of undies affects his testicular function as measured in a number of ways, including reproductive hormones and DNA fragmentation, she said.

I knew this when I was a teen. I’m 55 now. And yes I wear boxers.
Old news. This started turning-up in womens’ magazines in the 80’s.
This has been known for decades.
Yup, I remember hearing this 30 years ago.
That is hilarious, but has me thinking about vibrations. No, not those vibrations! Long haul truckers and freuent motorcycle riders experience continual vibrations most people are not subjected to otherwise. I know long haul trucers and motorcyclists can exerience bladder/urination problems from the constant vibration. Now I wonder if that affects fertility. Hmmm.
I willsay this much. Briefs as birth control would be awesome, if it was that easy.
Sounds nuts.
Is this supposed to be a new study? I heard this decades ago. Might’ve been a Seinfeld episode about it, too.
Old news.......
