Study summary

The aim of this prospective multicenter study is to investigate the influence of a predetermined embryo transfer on day 6 compared to a predetermined embryo transfer on day 5. The study population consists of the control group (predetermined embryo transfer on day 5) and the study group (predetermined embryo transfer on day 6). The primary endpoint is the clinical pregnancy rate (detection of a gestational sac) per embryo transfer and the secondary endpoint is the abortion rate per clinical pregnancy. The data from the multicenter study are obtained at three test centers (Fertility Center Dortmund, Fertility Center Essen and Fertility Center Bad Münder).
