[Prospective studies into pregnancies of primiparae with record of therapeutic termination of previous pregnancies or of spontaneous abortion and assessment of fertility. First communication (author's transl)].

A comparison was made between 535 primiparae with a record of therapeutic termination of previous pregnancies, 305 primiparae with previous abortion, and 501 primiparae without any record of spontaneous or medically induced abortion, all of these being compared for their prepartum, intrapartum, and postpartum phases as well as the conditions of their children delivered in their first intrapartum, and postpartum phases as well as the conditions of their children delivered in their first full-term pregnancy.--Significant accumulation of spontaneous abortions, bleeding in the first and second thirds of pregnancy, as well as postpartum complications were recordable from women with record of induced or spontaneous abortions, in comparison with primigravid primiparae. All probands with record of previous termination of pregnancies exhibited a trend towards premature births, yet, with no significant accumulation of these. Significantly increased use of therapeutic and prophylactic measures, such as cerclage and tocolysis, should be taken into due consideration, in that context.
