Strassmann's operation in the presented manner has proven to be a valuable intervention in the case of infertility due to uterus bicornis or subseptus. The pregnancy rate observed after the operation was 92%, while the rate of abortion was 16%. Strassmann's operation requires smaller incisions compared with other metroplasties and was therefore continued. The establishment of the so-called 'abortus habitualis consulting hours' has led to a dramatic increase in the indication of a metroplasty. The proportion of patients with uterine malformations among those presenting with abortus habitualis amounts to 18%. Delivery by cesarean section 1-2 weeks before term should be taken into consideration from the obstetrical viewpoint. However, the decision for this treatment mode is also governed by the wish of the patient for minimal risk.
