RESUMO
Adolescent's sexual health, in particular the risk of unwanted pregnancies and sexually transmitted infections (STIs), is a complex topic that deserves special attention. Confidential care and non-stigmatizing attitude as well as working with sexual health counsellors are strongly recommended. If an adolescent consults with an adult, it is beneficial to proceed stepwise in order to promote patient's autonomy and to build a relationship of trust with both of them. A focused approach of the teenager, adapted to its needs, as well as techniques such as Quick start and bridging, can improve compliance to contraception. Regarding the risk of STIs, primary prevention remains essential. The most effective prevention currently consists in systematic condom use.
