title: [Contraception in adolescence and perimenopause].
abstract: The risk-benefit-ratio of hormonal contraception (OC) is positive in adolescents as well as in women over 40 years of age if some essential rules are respected. In adolescents, the acquirement of a normal peak bone mass has to be guaranteed by the use of the OC. The dosage of the OC has to be adapted individually to the basic hormonal situation. In women over 40, contraindications such as hypertension, obesity, smoking or dyslipidemia have to be actively excluded. In both groups of age, the risk of a correctly indicated OC is inferior to the risk of an unwanted pregnancy.
