A Randomized Trial of Progesterone in Women With Bleeding in Early Pregnancy

Abstract

(N Engl J Med. 2019;380(19):1815–1824) This study aimed to determine whether the controversial use of progesterone therapy in women with early bleeding in pregnancy could result in a higher incidence of live births than use of a placebo. It was a multicenter, randomized, double-blind, placebo-controlled trial to evaluate progesterone, as compared with placebo, in women with vaginal bleeding in early pregnancy. Women received vaginal suppositories of progesterone, or a placebo, from presentation of bleeding to 16 weeks to determine if progesterone therapy helps improve pregnancy outcomes for women with vaginal bleeding in early pregnancy.
