Researchers at the University of Indiana questioned 436 men between the ages of 18 and 67 about the fit of condoms recently used in penetrative sex with a female partner.
Almost half of those questioned reported a badly fitting condom during sex in the last three months. These participants were 2.5 times more likely to report breakage or slippage as those whose condoms fitted well, and five times more likely to report penile irritation.
Men who reported poorly fitting condoms may also be more likely to experience sexual dissatisfaction, as may their female partners, the researchers said.
Dr Richard Crosby and co-authors concluded ‘men and their female sex partners may benefit from public health efforts designed to promote the improved fit of condoms'.
