Skinny jeans are squeezing sartorially adept males too tightly in a particularly sensitive area, new research shows.
British researchers warn that the garment - made popular by celebrities including Jude Law and Russell Brand - is responsible for the occurrence of health problems around the groin, The Daily Telegraph reports.
The skinny jean has been linked to inflictions including twisted testicles, bladder weakness, urinary tract infections, low sperm counts, and fungal irritations, the report said.
"I have seen several cases of men who have twisted their testicles due to wearing jeans that are far too tight," high-profile British GP Hilary Jones told the Telegraph.
"Wearing tight-fitting clothing over a prolonged period of time can lead to urinary tract infections leading to overactivity of the bladder."
A study of 2000 British men revealed that one in 10 experienced an unpleasant side effect of wearing skinny jeans.
Half reported groin discomfort, more than a quarter had bladder troubles, and one in five suffered a twisted testicle.
The latter condition occurs when tight trousers prevent the spermatic cord from moving freely, meaning it twists and possibly cuts off blood, requiring immediate surgery.
