Assisted hatching and Pre-implantation Genetic Diagnosis

Key benefits

  • Assisted hatching involves creating a hole in the outer membrane of the embryo to facilitate escape of the embryo. Has not been shown to significantly improve success rates across the whole infertile population; however it appears to be of some benefit in selected groups of patients.
  • Pre-implantation Genetic Diagnosis (PGD) involves removal of one or two cells from an embryo and examination of the cells for specific chromosomal abnormalities. These can be for the presence or absence of the chromosome or for specific gene defects, called single gene defects. The embryos are biopsied in our laboratory and the cells sent away to reference genetic laboratories for analysis.
  • Both techniques are employed only in selected cases.
