ABSTRACTEmbryo implantation represents the most critical step of the reproductive process in many species, to be successful requires a receptive endometrium, functional embryo at a stage of embryonic development and proper dialogue between embryonic and maternal tissues. Hatching is the process in which the blastocyst gets rid of the zona pellucida to be implemented. The failure in this factor can lead to reproductive problems, even under assisted reproduction techniques. Assisted hatching is a technique used in assisted reproduction laboratories to improve performance in the process of fecundation or in vitro fertilization. This technique is based on impairment or section of the zona pellucida using different techniques. In this review, the most common indications and techniques used to perform this procedure and improve success rates in assisted reproduction techniques are synthesized.
