The government has announced a £26.8 million drive aimed at improving access to contraception.
More than one in ten sexually active women do not use contraception, increasing the risk of unplanned pregnancies and threatening their sexual health.
Figures also show that the highest rates of abortion are among 20 to 24-year-olds, something that the government is keen to address.
Extra money will therefore be ploughed into local health teams, enabling them to promote long-term methods of contraception such as implants and injections.
Public health minister Dawn Primarolo commented: "There is increasing evidence of the key role contraception plays in preventing teenage pregnancy.
"We need to use this evidence and improve access to the full range of methods of contraception in many areas, particularly those with high and increasing rates of teenage pregnancy and high rates of abortion."
The minister was speaking at the launch of a new UK charity, the Association for Young People's Health.
