New research has shown that chlamydia is more common among men than women, yet fewer men are tested for sexually-transmitted infections (STIs).
According to Lloydspharmacy, some 13 per cent of men who bought chlamydia testing kits had a positive result, compared to six per cent of women.
However, just 28 per cent of guys have been screened for STIs – a significantly lower proportion that the 38 per cent of women who have been tested.
The survey also showed that men are more likely to have unprotected sex, with 13 per cent admitting to sleeping with more than one person without a condom in the last five years, compared to seven per cent of girls.
Clare Kerr, head of sexual health at Lloydspharmacy, said the results of the research were "worrying".
"Many STIs don’t have any obvious symptoms, so men could be putting both themselves and their partners at risk by delaying tests," she remarked.
The publication of the survey comes after experts at the Health Protection Agency warned that gonorrhoea was becoming more difficult to treat due to people’s growing resistance to the antibiotics used to combat it.
