Use of injectable, progestin-only contraceptives including the 3-monthly injectable depot-medroxyprogesterone acetate (DMPA) and the 2-monthly injectable norethindrone enanthate (NET-EN) appear to be increasing rapidly in such areas. Thus, understanding whether women's use of hormonal contraception increases their risk of HIV acquisition is critically important.
