Compared with looser undergarments, for instance, tighter options were linked to 18 percent higher odds of producing less semen.
Tight undies were also linked to 12 percent higher odds of having fewer motile sperm, 48 percent higher odds of having fewer normally shaped sperm, and 108 percent higher odds of having more sperm with DNA fragmentation or damage.
In a secondary analysis, researchers also found that erectile dysfunction and premature ejaculation were more prevalent in the tight underwear group.
“In conclusion, tight underwear was associated with poorer semen quality and a higher prevalence of erectile dysfunction and premature ejaculation,” the authors write, led by urologist Xue-Chun Hu from the University of Science and Technology of China (USTC).



Good to know for people who don’t want to have kids.
How long before the billionaires ban surgical methods of birth control, too?
Might seem strange to ask after Dems won a few seats, but remember, money is power and power corrupts, no matter which color banner they stand under.
For men? Never. For women? Already
Bah, we can boil our boys a few times a year and never have to worry bout crotch goblins
Those numbers don’t help if you want fewer kids. They only harm when you want to have some.
Yeah I wouldn’t consider tight underwear a viable contraceptive.
Hysterectomies are notoriously difficult to get without husband’s permission in the US. Even when the person trying to yeet their uterus needs it gone for medical reasons. Not a long shot to see it attempted yet within Trump’s two years left.
As for stopping men from getting vasectomies? Lol, yeah right.
I got to get my V done by Dr. Dick Chopp.
I know this is a joke comment, but the procedure is pretty quick with minimal recovery time. I highly recommend it.
Can confirm, but it was not a joke. My vasectomy was done by Dr. Dick Chopp.
EDIT: He was a master of marketing.

That’s incredible!
The scissors in the picture adds, or removes, a little something.
Thought for a moment that V was short for vajaj. Bottom surgery is one hell of a contraceptive.
