Preimplantation Genetic Screening
Ensuring Healthy Embryos for Successful Pregnancy
Preimplantation Genetic Screening (PGS) is a new reproductive technology that is used to screen the embryos for chromosomal abnormality before implantation. It is performed to ensure maximum chances of a successful pregnancy while reducing the likelihood of genetic disorders and failure of implantation.
Who Should Apply Preimplantation Genetic Screening?
PGS is best suited for individuals and couples who:
- Experience recurrent miscarriages – Usually linked with chromosomal abnormalities.
- Are of advanced maternal age (35+ years) – Genetic disorders are more likely.
- Have experienced repeated IVF failure – PGS increases embryo selection.
- Want to reduce risk of genetic disease – Detects chromosomal aneuploidies (e.g., Down syndrome, Turner syndrome).
- Are planning single embryo transfer (SET) – Offers guarantee that healthiest embryo is chosen.
The Step-by-Step Process of Preimplantation Genetic Screening:
1. IVF & Embryo Development
- Eggs are retrieved, fertilized in a laboratory, and developed into embryos (Day 3 or Day 5).
- Genetic analysis is done only on the healthy embryos.
2. Embryo Biopsy – Cell Removal for Testing
- A small number of cells are removed from every embryo gently without harming its development.
- It is performed on Day 5 or Day 6 when the embryos are at the blastocyst stage.
3. Genetic Analysis – Screening for Chromosomal Abnormalities
- The cells are retrieved and are studied with detailed chromosomal screening using newer genetic tests (Next-Generation Sequencing, Array CGH, or PCR-based testing).
- Identifies missing, excess, or abnormal chromosomes.
4. Embryo Selection & Freezing
- Normal chromosomally healthy embryos are transferred.
- The remaining healthy embryos can be frozen for future use.
5. Embryo Transfer – Placing the Best Embryo
- One good-quality embryo is placed in the uterus.
- It is painless and non-surgical.
6. Pregnancy Test & Follow-Up
- Pregnancy test is conducted 10-14 days post-transfer.
- Early pregnancy is closely monitored and cared for.
Benefits of Preimplantation Genetic Screening:
- Increases IVF Success Rates – Improves implantation and pregnancy rate.
- Reduces the Risk of Genetic Disorders – Screens for chromosomal abnormalities.
- Reduces Miscarriage Rate – Prevents chromosomally defective pregnancies.
- Promotes Single Embryo Transfer (SET) – Lowers multiple pregnancy risk.
- Improves Family Planning – Allows couples to make informed reproductive choices.
Risks & Considerations
- Not a Guaranteed Outcome of Pregnancy – PGS only improves embryo selection and not implantation.
- Rare Chances of Damage to the Embryo – While minimal, there is always the slightest chance of affecting embryo viability.
