Overall, sixty eight pregnancies transpired for every 1,000 ladies aged 15-19 in 2008. Nearly 7% of 15-19-12 months-previous ladies come to be pregnant each and every 12 months. A 2008 review by the CDC discovered that just one in four teen ladies, or an approximated three million women, has an STI. For girls, even modest involvement in sexual experimentation elevates melancholy hazard.
