A systematic review of 25 studies, covering 346,000 women, to determine whether abortion care for adolescent and young women differs from abortion care for older women—with a focus on efficacy, safety and acceptability. It concludes that limited evidence indicates that abortion of all types at all gestational ages is effective, acceptable and safe for adolescents and young women, and strongly recommends offering adolescents a full range of contraceptives after abortion, including intrauterine contraception.
