Preimplantation Genetic Testing (PGT) is an advanced reproductive technology used during In Vitro Fertilization (IVF) to evaluate embryos for genetic or chromosomal abnormalities before they are transferred into the uterus. This powerful tool helps improve pregnancy success rates, reduce the risk of miscarriage, and prevent the transmission of inherited disorders.
At Viva Fertility Clinic, we offer state‑of‑the‑art PGT services to help individuals and couples make informed decisions and increase their chances of having a healthy baby.
PGT involves analyzing a few cells from an embryo (usually on Day 5 or 6 at the blastocyst stage) to assess its genetic health. Only embryos that are chromosomally normal or free from specific genetic diseases are selected for transfer.
PGT is categorized into three main types:
Screens embryos for abnormal chromosome numbers (e.g., Down syndrome, Turner syndrome). Purpose: Improve implantation rates and reduce miscarriage.
Detects single‑gene disorders such as:
Sickle cell disease
Cystic fibrosis
Thalassemia
BRCA mutations Purpose: Prevent transmission of inherited diseases.
Identifies chromosomal structural abnormalities such as translocations or inversions. Purpose: Reduce the risk of implantation failure or recurrent miscarriage.
PGT is recommended for:
Women aged 35 and above
Couples with recurrent pregnancy loss
Individuals with a family history of genetic disorders
Couples with previous failed IVF cycles
Men or women with chromosomal abnormalities
Carriers of single‑gene disorders
Same‑sex couples or individuals using donor gametes who want additional reassurance
Eggs and sperm are combined in the laboratory to create embryos.
A few cells are gently removed from the embryo at the blastocyst stage. The embryo remains unharmed and is frozen while testing is performed.
The biopsied cells are examined using advanced genetic technologies such as:
Next‑generation sequencing (NGS)
Polymerase chain reaction (PCR)
Microarray analysis
Only genetically normal or disease‑free embryos are selected for transfer.
A healthy embryo is transferred into the uterus during a future cycle.
Higher IVF success rates
Reduced risk of miscarriage
Lower chance of genetic disease transmission
Improved embryo selection
Fewer failed IVF cycles
Greater confidence and peace of mind
While PGT is highly advanced, it has some considerations:
It does not guarantee pregnancy.
It cannot detect all genetic conditions.
Embryo biopsy requires specialized expertise.
Some embryos may not survive to the biopsy stage.
Ethical and emotional factors may influence decision‑making.
At Viva Fertility Clinic, we provide thorough counselling to help patients understand the benefits and limitations before proceeding.
Preimplantation Genetic Testing is a transformative tool in modern fertility care. By identifying healthy embryos before pregnancy, PGT increases the chances of a successful outcome and helps families avoid the burden of inherited genetic conditions.
At Viva Fertility Clinic, we combine cutting‑edge technology with compassionate care to help you build the healthiest family possible.
