The outer covering of embryo is called Zona pellucida is a cover protecting the integrity of the blastomeres & further growth inside. They should give way to hatch to expose embryonic cells to the inner uterine environment, to get (blastocyst) get attached with endometrial lining of uterus for proper implantation. When they are resistant for natural enzymes in the endometrial cavity which help in dissolving this shell hatching process is hampered resisting nidation, thereby failing the efforts of embryo to grow further.
“Laser Assisted Hatching” system, augments the success rates significantly by improving the implantation rates. This technique helps the blastocyst to hatch in time, by which the implantation potential is improved. This procedure will help the eggs of elderly women whose eggs will have thicker ZONA PELLUCIDA. Cryopreserved (Frozen) Embryos and Blastocysts also have thicker ZONA, which will be helped out by this procedure.
