Men with STIs 'may smell'

Men who catch a sexually transmitted infection (STI) as a result of failing to wear a condom while having intercourse may find their body scent is affected as a consequence.

This is because scientists in Russia have discovered guys with gonorrhea can smell putrid to females, MSNBC reports.

Investigators from the Institute of Cytology and Genetics in Novosibirsk - which was first organised in 1957 - looked into the matter to see if humans, like animals, are less attracted to would-be mates who are infected with disease.

Mikhail Moshkin, lead author of the report, which has been published in the Journal of Sexual Medicine, noted: "Our research revealed that infection disease reduces odour attractiveness in humans."

Tests involved in the study saw women rank the smell of sweat samples - taken from male armpits - of men both with and without the STI.

The scent of infected men was positioned less than half as high as that from healthy participants.
