Skinny jeans might be “in” in mens fashion, but a new study has medical experts warning of the health consequences for this new fad.

Medical experts say wearing tight-fitting jeans could cause bladder weakness, an increased risk of urinary tract infection and, in some severe cases, twisted testicles.

TENA Men, the group behind the research, said 10 per cent of the 2,000 men studied already suffered some negative side effect as a result.

TENA brand ambassador, Dr. Hilary Jones, warned that wearing clothing that is tight or restrictive around the groin over a prolonged period of time could be damaging to health, causing low sperm counts and fungal infections among other things.

“I have seen several cases of men who have twisted their testicles due to wearing jeans that are far too tight.

“My advice would be to make sure you leave plenty of room around the groin area and that your pants and trousers feel comfortable so you’re not being restricted in any way.

“Please don’t put style before health.”

The study was carried out in Britain where three in ten men suffered discomfort from tight jeans and 40 per cent of men confessed to sacrificing comfort to favor style.

Zoe Brimfield, TENA Men Brand Manager says:

“With this survey we were keen to highlight that while men may like the look of tight-fitting jeans, it’s important that they are not compromising their health.”
