Viratamasen P The aim of this study was to investigate the efficacy of two different embryo biopsy
techniques, direct aspiration and partial zona dissection (PZD)-push, on subsequent in vitro
and in- vivo development of 8-cell stage mouse embryos. It was found that the rates of normal
blastocyst formation and hatching blastocysts of direct aspiration, PZD-push, solution control
and control embryos were not significantly different (80.8%, 81.6%, 84.5%, 86.7% and
71.9%, 72.3% and 74.6%) respectively. There was, however, a significant reduction in rate of
complete hatching blastocysts (P
