Abstract

In this retrospective, matched-paired study, yeast in the embryo culture medium was associated with a trend toward decreased developmental competency that was more pronounced when observed early in culture. Because live births occurred after transfer of embryos in the yeast-contaminated group, we concluded that yeast contamination is not a reason to cancel embryo transfer (ET).
