Preimplantation Genetic Diagnosis (PGD) and Preimplantation Genetic Screening (PGS) are advanced genetic-testing techniques used in conjunction with IVF to assess embryos before they are transferred to the womb. The goal is to identify embryos free from genetic disorders or chromosomal abnormalities — giving you the best possible chance of a healthy pregnancy and baby.
Our PGD/PGS protocols are designed to identify single-gene disorders or chromosomal abnormalities before embryo transfer, minimizing risk of inherited or genetic issues in your child.
Screening ensures transfer of healthy embryos, which improves implantation rates, reduces miscarriages and increases chances of live birth.
Recommended for couples with a family history of genetic disease, recurrent pregnancy loss, repeated IVF failures, or advanced maternal age.
We use advanced technologies (e.g. NGS, comprehensive chromosome screening) for precise and reliable embryo evaluation.
If you and your partner have concerns about genetic disorders, chromosomal abnormalities, previous IVF failures or miscarriages — PGD / PGS offers an extra layer of safety. At Global Fertility Services, our fertility specialists and genetic counsellors will assess your case thoroughly, advise on the best approach, and support you throughout with compassion and clarity.
We review your medical history, family history, genetic risks, and discuss whether PGD or PGS is recommended. We explain benefits, limitations and possible outcomes.
A few cells are gently removed from developing embryos for genetic testing (chromosomes or specific genes), without harming embryo viability.
We use specialized lab spaces and equipment dedicated to HIV-affected cycles to avoid cross-contamination. Embryo culture, selection, and transfer follow standard ART best-practice protocols.

PGD looks for specific genetic disorders (single-gene mutations); PGS checks overall chromosome normality (aneuploidies, structural abnormalities).
Usually on Day 5 or 6 — when embryo reaches blastocyst stage. A few cells are removed gently for testing.
Genetic testing is highly accurate (with advanced techniques like next-generation sequencing), but no test can guarantee 100% — some rare or unknown conditions may not be detected.
When done by experienced embryologists at blastocyst stage, biopsy risks are minimal and embryos remain viable for transfer or freezing.
It improves chances significantly but does not guarantee — success still depends on multiple factors including maternal health, uterine environment, embryo quality, and other medical conditions.
