There is controversy whether teratospermia is associated with poorer IVF outcomes and if ICSI may overcome this deficit. The debate likely lies in study heterogeneity, poor adjustment for confounders, and inter-observer variation in sperm morphology assessment. Given the current literature, a shift in practice was implemented at our center in February 2017, whereby teratospermia was no longer a criterion for ICSI. We hypothesized that, despite decreasing ICSI rates, we would see no change in ART outcomes.
