Overview
Chromosome abnormalities may be affected by hormonal stimulation and / or laboratory conditions. In this study we analyzed data from egg donor cycles that underwent PGS in different centers. Confounding factors such as fertility indication, paternal age, maternal age, and others were eliminated. We found a strong indication that different fertility centers have different aneuploidy rates, and even different doctors from the same center.
