Age of first sexual intercourse may impact teens' risk of acquiring sexually transmitted infections

A new study shows that earlier initiation of sexual intercourse increases the odds of experiencing sexually transmitted infections (STIs). Also, if the age at the time of first sexual intercourse is during or near to an adolescent's sexual maturation period, the likelihood of experiencing STIs increases.

The findings, which are published in The Journal of Sexual Medicine, suggest that it is important to consider the time period of first sexual intercourse when considering STI risk. The results will also be a useful reference for further studies of adolescents' health and behavior.
