Live offspring efficiency of laser-assisted IVF (LAIVF) and conventional IVF (Conv IVF) using vitrified-warmed (V-W) and fresh oocytes.

Resorption is abbreviated as resorp, and implantation is abbreviated as implant.aMeans ± SEM of % viable E17 embryos and % live pups were calculated from % viable E17 embryos or % live pups [# viable E17 embryos or # live pups/# two-cell embryos transferred (transf) *100] of each replicate; 2–4 replicates were included in each group where SEM is indicated.bOne replicate included number of live pups obtained from 2 embryo transfer surgery recipients co-housed together post-operatively, with a combined total of 56 transferred two-cell embryos.cMean ± SEM of % live offspring was calculated from % viable E17 embryos and live pups (# viable E17 embryos and live pups/total # two-cell embryos transferred *100) of each replicate; 3–7 replicates were included in each group where SEM is indicated.NA indicates data not available; too few two-cell embryos were obtained via conventional IVF to evaluate live pup efficiency.
