In order for an embryo to be implanted, it must escaped from its zona pellucida (the shell). Laser assisted hatching is a technique that involves creating a small hole in the zona pellucida using laser, hence increasing the implantation rate. 
  • Advanced maternal age ≥ 38 
  • Repeated implantation failure
  • Embryos with thick or abnormal zona pellucida
