[Is hormonal therapy still justified in imminent abortion? (author's transl)].

In a prospective study, 300 women were treated during 1976 to 1978 alternatingly with hormones or placebo, the comparability of both groups being established in respect of certain influencing factors. No statistically confirmed difference was found in the total success rates of both types of treatment. The age of the pregnant women, and any previous abortions, did not represent any risk factor for imminent abortion.
