Abstract Background When discussing termination of pregnancy (TOP) after the first trimester, the main foci are the ethics and psychological reasoning/consequences. In daily clinical practice, physicians are often faced with affected women querying the frequency of their condition(s) and decisions made by women in similar situations. The present study aimed to provide an overview of a representable number of such cases. Methods Cases of TOP beyond 14 + 0 weeks of gestation were collected between January 2000 and December 2017 in the Department of Obstetrics. Fetal and/or maternal medical causes leading to TOP were extracted and presented. Results A total of 1746 TOPs ≥14 + 0 weeks were performed. Reasons leading to TOP were subcategorized into 23 groups. The main medical diagnoses were trisomy 21 (15.5%), neurological malformations (11.0%), and cardiac and major vessel malformations (7.9%). There was no statistical difference concerning maternal age or gravida/para between the groups. The average gestational age (GA) was 21.0 weeks, varying between 16.2 and 24.2 weeks in the 23 subgroups, with an average of 23.6% per year of TOPs after viability. Conclusion An overview of the various causes of TOP and their frequency within a large dataset are shown here. According to data provided by the German Federal Statistical Office, the overall number of TOPs has declined over the past two decades; however, the number and percentage of TOPs beyond viability have increased continuously in Germany. Only early detection of maternal and fetal constitution can prevent a portion of TOP after viability.
