Cohort follow-up of couples with primary infertility in an ART programme using frozen donor semen

Abstract

Background: This study was designed to determine the crude cumulative live-birth rates in a cohort initiating frozen donor semen treatment until completion. Methods: This cohort study included 588 couples with primary infertility in one University Hospital centre. The treatment sequence involved first artificial insemination (AID) followed by IVF if necessary (IVF-D). Live birth, drop-out for personal or medical reasons and recourse to IVF-D were recorded for all patients. Live births and drop-out were expressed both as rates per cycle and crude cumulative rates. Results: At the completion of AID and IVF-D cycles, 406 couples in the cohort (69%) achieved a live-birth and 182 couples (31%) discontinued treatment. In most cases, couples stopped treatment for personal reasons (74%) whereas fewer couples were denied further treatment for medical reasons (26%). Conclusions: This is the first report on the crude cumulative live-birth rate in a cohort after AID and IVF-D cycles. Although calculation based on crude cumulative live-birth rate shows lower results in comparison with life table analysis, this method allows patients to obtain an insight into their actual chances of achieving a successful pregnancy.
