[Our approach to the diagnosis and treatment of the causes of infertility].

The authors put forward their own scheme of investigating possible causes of infertility. In everyday clinical routine the results of such investigations are limited. Most useful data are obtained by a detailed anamnesis, hysterosalpingography, bacteriological analysis, and cytogenetics. In the therapy of spontaneous abortion strict rest is recommended. Gestagen therapy is applied in bleeding in the first trimester only when fetal life is proved (ultrasound). Early protecting cerclage is to be performed between the 14th and the 16th gestation week. The importance of a positive psychological relation between physician and patient is emphasized.
