What is PGS? Why is it used?

PGS, Preimplantation Genetic Screening, is a genetic test that analyses biopsied cells from embryos produced by in vitro fertilization (IVF) techniques.

PGS determines whether the embryos are chromosomally normal (euploid) or not (aneuploid), thus giving the chance to transfer chromosomally normal embryos that are more apt to successfully implant and develop into a pregnancy.

Widely accepted indications for PGS are those in which there is an increased risk for the couple of generating aneuploid embryos: advanced maternal age; history of recurrent miscarriages or pregnancies/children with chromosomal abnormalities; recurrent IVF failure; chromosomal translocation carriers; gender selection.


CryoSend regularly transports embryos for PGS screening from and to Japan and other Asian countries. If you are looking for PGS screening options, feel free to contact us for more information.
