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

Abstract

Three groups of probands (conditions following induced or spontaneous abortion and primigravid primiparae) were compared for duration of pregnancy, birth weights, and occurrence of premature births, all against the normal percentiles, was not recordable from newborns whose mothers had undergone abortions during their first gravidity. Very moderate accumulation of foetuses with birth weights of 2,000 g or below was attributed to a general increase in the number of premature births in lower weight classes. Yet, the number of women with record of induced abortion who reached the percentile values, depending on duration of pregnancy, was higher than that of women who had never been pregnant before.
