A retroprospective study comparing three different assisted hatching techniques.

The purpose of this study was to determine the effect of four different assisted hatching techniques on pregnancy rates in women with prior IVF failure in fresh IVF cycles. The results suggested that assisted hatching utilizing laser, chemical, or microsurgical techniques increases both implantation and pregnancy rates.
