Understanding PGT: A Comprehensive Guide to Preimplantation Genetic Testing at Oasis

 

When embarking on the journey toward parenthood through assisted reproductive technology (ART), many couples seek every possible advantage to ensure a successful pregnancy. One of the most significant advancements in reproductive medicine is Preimplantation Genetic Testing (PGT). This innovative approach allows for the screening of embryos for genetic abnormalities before transfer, increasing the likelihood of a healthy pregnancy and reducing the risk of genetic disorders.

In this comprehensive guide, we’ll explore what PGT is, how it works, the types of testing available, its benefits, limitations, and how Oasis Fertility Centre can support you through this process.

What is PGT?

Preimplantation Genetic Testing (PGT) is a laboratory procedure performed on embryos created through in vitro fertilisation (IVF) to evaluate their genetic health prior to implantation. By analyzing the genetic material of embryos, clinicians can select those most likely to result in a healthy pregnancy, thereby improving success rates and reducing the chances of genetic diseases.

How Does PGT Work?

Ovarian Stimulation and Egg Retrieval

The journey begins with ovarian stimulation to produce multiple mature eggs, which are then retrieved via a minimally invasive procedure.

Fertilization

The retrieved eggs are fertilised with sperm in the laboratory, using either conventional IVF or Intracytoplasmic Sperm Injection (ICSI).

Embryo Development

The fertilised eggs develop into embryos over several days (typically 3-5 days).

Biopsy of Embryos

A few cells are carefully removed from each embryo in a process called embryo biopsy. This step is performed at specific developmental stages, such as the blastocyst stage (day 5 or 6).

Genetic Analysis

The biopsied cells are sent to a specialized genetics laboratory, where they undergo genetic testing to identify chromosomal abnormalities or specific gene mutations.

Embryo Selection and Transfer

Based on the results, the embryologist and fertility specialist select the healthiest embryos for transfer, increasing the chances of a successful pregnancy.

Types of PGT and What They Screen For

There are different types of PGT, each designed to detect specific genetic issues:

 

 

PGT-A (Preimplantation Genetic Testing for Aneuploidy)

Screens for chromosomal abnormalities such as trisomies (e.g., Down syndrome, Edwards syndrome). It’s commonly used for women of advanced maternal age or couples with recurrent pregnancy loss.

 

PGT-M (Preimplantation Genetic Testing for Monogenic Disorders)

Identifies specific gene mutations associated with inherited genetic disorders, such as cystic fibrosis, Tay-Sachs disease, or sickle cell anemia.

 

PGT-SR (Preimplantation Genetic Testing for Structural Rearrangements)

Detects structural chromosomal rearrangements, such as translocations or inversions, that can cause infertility or miscarriage.

Benefits of PGT

Implementing PGT in your fertility journey offers several advantages:

Increased Pregnancy Success Rates

Selecting genetically normal embryos enhances the likelihood of implantation and reduces miscarriage rates.

Reduced Risk of Genetic Disorders

PGT allows for early detection of inherited conditions, providing peace of mind for prospective parents.

Optimized Embryo Utilization

By identifying the healthiest embryos, couples may need fewer IVF cycles.

Informed Decision-Making

Detailed genetic information empowers couples to make informed choices about their reproductive options.

Is PGT Right for You?

Your fertility specialist will evaluate your individual circumstances, including age, reproductive history, and genetic risks, to determine if PGT is appropriate. Couples with a history of genetic disorders, recurrent pregnancy loss, or advanced maternal age often benefit most from this testing.
