When fashion hurts ... A British study found that one in every 10 men had experienced an unpleasant side effect of wearing skinny jeans.

Leg-hugging strides may be the pinnacle in pants fashion, but skinny jeans are likely to be squeezing their male hosts too tight in a particularly sensitive area, new research shows.

British researchers warn that skinny jeans are responsible for the occurrence of health problems around the groin, British newspaper The Daily Telegraph reports.

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

The skinny jean has been linked to inflictions including low sperm counts, twisted testicles, bladder weakness, urinary tract infections and fungal irritations, the report said.

Celebs such as Russell Brand have embraced the skinny pants look.

"I have seen several cases of men who have twisted their testicles due to wearing jeans that are far too tight," British GP Hilary Jones told the newspaper.

"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 the men in the study reported groin discomfort, while more than a quarter had bladder troubles. 

One in five suffered a twisted testicle, a condition that occurs when tight trousers prevent the spermatic cord from moving freely, meaning it twists and possibly cuts off blood. This requires immediate surgery.

Wearing tight pants has also been linked to lower sperm counts as a result of the scrotum becoming overheated and harming the delicate sperm production process. Men who are trying to conceive with their partner are encouraged to wear looser-fitting underpants and outer clothes.
