A charity has said that it has not seen any improvement in overall sexual health statistics, but there are other factors to take into account.
Victoria Sheard, deputy head of policy at the Terrence Higgins Trust, noted that there were 400,000 new diagnoses of sexually transmitted infections (STIs) in 2008, according to the Health and Protection Agency.
She pointed out that this is a slight increase on 2007 figures, even though the Office for National Statistics reported increased use of contraception this week.
Ms Sheard explained: "Obviously the picture is slightly complicated by the fact that more people are coming forward and testing for STIs and being diagnosed."
In her view, statistics for infections will begin to reduce in the next few years if people continue to use contraception.
It is encouraging to see more people being tested for STIs though, since this will help restrict the spread of illness because people will realise that they have a condition, she added.
