PGS

Preimplantation genetic testing (PGS) offers an alternative for these couples, where the genetic test is performed on the embryos before transfer (Preimplantation embryo). In PGS, couples go through routine IVF/ICSI procedures to generate embryos in vitro, the day-5 embryos (Blastocyst) are biopsied, and the genetic test is performed on the biopsied cells. Later normal embryo is transferred. Abnormal embryos usually destroy depends on mosaicism. But that doesn’t mean that all couple need PGS. PGS should be reserved for few couples with certain clinical conditions.
