PGD stages involve structural analysis of embryo’s genetic make-up during IVF applications. End result of these stages is to select only the healthiest embryos to be implanted. PGD applications are collectively termed as “pre-implantation genetic diagnosis”.

 

The advantages of PGD

  • Promotes IVF application success rates.
  • Increases successful clinical pregnancy rates.
  • Decreases potential risk for abortion.
  • Minimizes medical needs in terminating pregnancies.
  • Decreases the rate of multiple pregnancies.
  • Allows for financial savings as well as helps alleviate psychological pressures caused by repeated unsuccessful IVF trials.
  • Allows for gender selection

How is PGD test performed ?

PGD test requirements should follow your doctor’s recommendations in cases where your condition is suitable for this type of a process.

The processes of healthy embryo selection happen in several stages:

  • Embryos are analysed through biopsy on their third day of development. One or two blastomeres (embryonal cell) are collected from each embryo for this purpose. It should be noted that biopsy procedure does not cause any damage to the normally developing embryos.
  • Acquired blastomeres are screened for genetic analysis. It takes 6 to 12 hours to gather results of this analysis.
  • Depending on analysis results, the healthy embryo chosen (or the embryo of which sex chromosome is identified, if applicable) for implantation is transferred to the recipient mother.

Transfer of healthy embryos ensures a normal course of pregnancy following successful implantations.
