Current challenges in contraception in adolescents and young women.

Purpose Of Review: Although developing countries have made much progress in expanding the availability and use of family planning services, the need for effective contraception is large, and growing because the largest cohorts in human history are entering their reproductive years. Not only regarding developing countries but also in developed countries, where the usual contraceptive methods, such as the oral contraceptives, intrauterine devices (IUDs) and condoms, have been available for decades, there have been many new advances in contraceptive technology in the last several years. New formulations of oral contraceptives, extended and continuous use of oral contraceptives and long-acting reversible contraceptives (LARC) may have a wider role in contraception and their increased implementation could help to reduce unintended pregnancy.
