What is Preimplantation Genetic Testing (PGT)?
Preimplantation Genetic Testing (PGT) is a powerful and evolving tool in reproductive medicine, allowing individuals and couples undergoing IVF to screen embryos for genetic abnormalities before implantation. As a leading PGT-A testing clinic in Ontario, Nahal Fertility Clinic is proud to offer state-of-the-art services in preimplantation genetic testing in Ontario, helping patients improve their chances of a successful pregnancy and reduce the risk of inherited disorders.
Primary Forms of PGT
- PGT-A (Aneuploidy): Evaluates embryos for abnormal numbers of chromosomes (e.g., Down syndrome, Turner syndrome). This is the most commonly performed test, aimed at reducing miscarriage risk and improving In Vitro Fertilization (IVF) success rates.
- PGT-M (Monogenic/Single-Gene Disorders): Screens for inherited disorders like cystic fibrosis, Huntington’s disease, and Tay-Sachs. Ideal for individuals or couples who are known carriers of specific conditions.
PGT-A: Elevating IVF Success with Chromosomal Precision What is PGT-A?
What is PGT-A?
Preimplantation Genetic Testing for Aneuploidy (PGT-A) is an advanced screening technique that identifies embryos with the correct number of chromosomes, thereby enhancing IVF outcomes. At our PGT-A testing clinic in Ontario, this process plays a crucial role in offering patients evidence-based treatment plans tailored for success.
How PGT-A Works
- Embryos are created through IVF and grown to the blastocyst stage (day 5 or 6).
- A small sample of cells is biopsied and sent to a specialized genetic laboratory.
- Geneticists assess the chromosomal composition to detect aneuploidies.
- Only euploid (chromosomally normal) embryos are selected for transfer.
Who Should Consider PGT-A?
PGT-A is especially recommended for:
- Women aged 35+
- Individuals with a history of recurrent miscarriage
- Couples with prior IVF failures
- Patients carrying chromosomal translocations
- Families who want to reduce the emotional and financial burden of unsuccessful IVF cycles

PGT-M: Preventing Inherited Conditions with Targeted Genetic Insight
Preimplantation Genetic Testing for Monogenic Disorders (PGT-M) helps families to avoid passing on single-gene diseases during IVF. This test is crucial for individuals or couples who carry a known inherited condition.
How PGT-M Works
- A custom genetic probe is created based on family history and confirmed diagnosis.
- Embryos are created and biopsied during IVF.
- High-resolution molecular diagnostics (such as PCR or NGS) are used to determine if the embryo carries the specific mutation.
- Only unaffected embryos are selected for implantation.
This technology empowers families to make informed choices and avoid difficult decisions later in pregnancy.
Who Benefits from PGT-M?
- Carriers of known single-gene mutations
- Those with a family history of genetic disease
- Parents who have had a child with a genetic disorder
- Anyone seeking to prevent genetic disease transmission

Frequently Asked Questions
Is PGT safe?
Embryo biopsy is a well-established, low-risk procedure when performed by trained embryologists in a controlled lab setting.
Does PGT guarantee a healthy baby?
While no test can guarantee perfect health, PGT significantly reduces the risk of specific chromosomal and genetic disorders.
How long do PGT results take?
Results are usually available within 7–14 days. During this time, embryos are safely frozen and stored until results are ready.
Is PGT funded in Ontario?
While some IVF cycles are publicly funded, PGT-A and PGT-M are typically not covered and are considered out-of-pocket expenses. Our financial team at Nahal Fertility can walk you through available funding and payment options
