Evaluating the Success of Injectable Contraceptives

Abstract

In the year 1950, injectable contraceptives were developed (containing only progestin). For the treatment of endometriosis and endometrial cancer as well as of painful menstrual periods, (dysmenorrhoea), excessive hair growth (hirsutism), and bleeding disorders, progestins were finally used. By the 1960's they were highly effective contraceptives and even recently, more than 10 millions women in 100 countries of the world including U.S.A., are using progestin, only injectables.
