A new contraception pill to be marketed as 'Ella', which can be taken several days after intercourse to prevent pregnancy, has been called 'completely unethical' by one gynecologist. "Proponents are heralding the approval of ella, which is already available in Europe, as a welcome expansion of women's reproductive options. Known as ulipristal acetate, it's chemically similar to the abortion drug RU-486 but will be dispensed in much smaller doses and labeled as an emergency contraceptive. Critics, however, warn that it's a potentially dangerous drug that was inadequately studied. It also reignites the debate about what defines contraception and abortion."
