Advanced reproductive technologies allow us to evaluate the genetic and chromosomal health of an embryo before it implants in the uterine wall. This specialized microscopic analysis is termed Preimplantation Genetic Testing (PGT). According to Prof. (Dr.) Abha Majumdar, utilizing PGT helps eliminate chromosomal abnormalities, lowers early miscarriage frequencies, and prevents the transmission of severe hereditary diseases to the next generation.
Human embryos can sometimes carry subtle genetic variances despite presenting a perfectly normal appearance under standard laboratory microscopes. Therefore, we utilize Next-Generation Sequencing (NGS) to analyse cell compositions across two distinct clinical testing options:
Professor’s Medical Insight: Biopsy of an embryo requires immense embryological skill. Our embryologist perform this procedure exclusively at the Day 5 or 6 blastocyst stage by safely sampling cells from the trophectoderm layer. This layer forms the future placenta, leaving the inner cell mass that develops into the baby completely untouched.
Integrating genetic analysis adds specific, highly structured laboratory phases to a standard IVF treatment cycle:
| Timeline Stage | Embryology Laboratory Action | Clinical Safety Metric |
|---|---|---|
| Day 5/6 Blastocyst | Embryos grow safely to the blastocyst stage until they develop distinct outer cell layer definitions. | Ensures the embryo is strong enough to withstand a cell biopsy. |
| Laser Biopsy | Using a high-precision medical laser, an embryologist safely removes 4 to 6 cells from the outer layer. | Preserves the integrity of the core inner cell mass. |
| Vitrification & Run | The blastocysts are safely frozen instantly via vitrification, while the harvested cell samples undergo advanced genetic sequencing. | Identifies genetically normal embryos with absolute accuracy. |
By transferring only euploid embryos during a subsequent frozen cycle, we bypass age-related biological challenges. Consequently, this precise selection drastically compresses the total time-to-pregnancy. It lowers early pregnancy failure risks and avoids the heavy emotional burden of recurrent miscarriages.
Ultimately, preimplantation diagnostics offer deep reassurance to couples carrying known genetic risks. Combining world-class molecular sequencing with protective laboratory environments ensures a safe, reliable, and deeply comforting path toward building a healthy family.
