The objective of this study was to assess the impact of assisted hatching (AH) on pregnancy rate (PR), clinical pregnancy rate (CPR), and implantation rate (IR) after a single failed, fresh, nondonor IVF cycle. Accordingly, we report that patients with one prior implantation failure benefit from AH with improved PR, CPR, and IR in a subsequent cycle.
