[The treatment of threatened abortion (author's transl)].

In a prospective study 265 patients with threatened abortions were divided into 2 groups. One group of 134 patients received treatment with Oestradiol benzoat and hydroxyprogesterone capronat. The other group of 131 patients received no hormonal treatment. Of the group treated with hormones 40.7% of the women had an abortion. Of the group treated with placebos 39.7% of the patients had an abortion. There was therefore no difference in the success rate of the treatment of threatened abortion irrespective of the administration of hormones or placebos. The value of hormonal therapy in the treatment of threatened abortion is therefore questionable.
