For men, the skinny jean fashion trend may have an unexpected side effect: experts are warning that the surge of tight-jean popularity among men is sparking a rise in painful testicular problems.

Medical experts, including UK television personality Dr. Hilary Jones, have reported an increase in injuries being caused by tight jeans, cites The Telegraph on Wednesday. “The trendy denims are causing twisted testicles, bladder weakness, and even urinary tract infections.”

Twisted testicles is a serious condition that occurs “when tight trousers prevent the spermatic cord from moving freely, meaning it twists and leads to testicular torsion which cuts off the blood supply requiring immediate surgery to prevent a gangrenous testicle,” noted the report.

Other dreaded side effects from overly tight jeans: low sperm count and fungal infections.

According to the UK press, Jones is working with TENA, a maker of hygienic products for people with incontinence, on a project to highlight the dangers.

”I have seen several cases of men who have twisted their testicles due to wearing jeans that are far too tight,” she reportedly said. ”My advice would be to make sure you leave plenty of room around the groin area and that your [UNDER]pants and trousers feel comfortable so you’re not being restricted in any way.”

”Please don’t put style before health,” Jones added.

For women, wearing skinny jeans can increase one’s chances of developing a vaginal yeast infection. Plus for both sexes, tight jeans have found to raise the risk of nerve compression, which can lead to tingling or numb thighs, according to health and fitness website RealBuzz.

A new survey finds that one in three homeless people in Boston are clinically obese, a number that casts in relief the strange reality of food in the 21st century United States.

Not long ago, malnourishment was embodied by emaciation. Now it’s far more likely to be hidden in folds of fat.

“This study suggests that obesity may be the new malnutrition of the homeless in the United States,” wrote the researchers, led by Harvard Medical School student Katherine Koh, in an upcoming Journal of Urban Health study.

The findings are the latest and most dramatic illustration of what’s called the “hunger-obesity paradox,” a term coined in 2005 by neurophysiologist Lawrence Scheier to describe the simultaneous presence of hunger and obesity.

Around that time, a vernacular sea change occurred, with “hunger” and its connotations of starvationreplaced by “food insecure,” a term more descriptive of people who might consume enough raw calories but not enough nutrients.

The paradox fit with a general modern relationship in the United States between weight and wealth. Whereas obesity was once a sign of wealth, it now tracks with poverty. The poorer and less food-secure people are, the more likely they are to be overweight or obese.

In an op-ed published Thursday in Sweden’s largest newspaper, Dagens Nyheter, the Swedish Cancer Society accused H&M of promoting a “deadly” beauty ideal, adding that the company would, “through its latest advertising campaign not only sell more bathing suits but also contribute to more people dying from skin cancer.”
