PGS (Preimplantation Genetic Screening)
- PGS is a genetic test performed on embryos to identify numerical chromosomal abnormalities (aneuploidy).
- The test is performed on embryos before transfer to the uterus.
- By analysing all embryos generated in an IVF treatment cycle those free of chromosomal aneuploidy can be selectively transferred.
- As a result, the pregnancy rates per transfer are significantly increased and the miscarriage rates decreased.
- Increases pregnancy rates per transfer. Selecting normal embryos can increase the pregnancy chances after transfer.
- Reduction in miscarriage rate In the general population, 25% of all clinical pregnancies end in miscarriage.
- Increase in the likelihood of having a healthy baby Some pregnancies with chromosomal anomalies can give rise to the birth of baby with a serious illness.
- Advanced maternal age: 35 years or above
- Recurrent miscarriages: 2 or more miscarriages of unknown cause
- Assisted reproduction cycles without pregnancy: 2 or more assisted reproduction cycles without pregnancy result
- Male factor: Males with low sperm concentration, below 5 million per ml
- Previous pregnancies with anomalies: 1 previous pregnancy with chromosome abnormality, especially in an assisted reproduction cycle
