title: The state of hormonal contraception today: benefits and risks of hormonal contraceptives: progestin-only contraceptives.
abstract: The progestin component of hormonal contraceptives accounts for most of their contraceptive effects. Several dosage forms of progestin-only contraceptives have been developed, including pills, injectables, implants, and intrauterine devices. Emergency contraceptives may also contain progestin only and are indicated for prevention of pregnancy following unprotected intercourse or contraceptive failure. Each form has benefits, some specific to the form. An understanding of benefits and risks allows clinicians a wider choice when recommending effective hormonal contraception.
