    What is PGT? | Genetic Testing of Embryos Explained

    PGT is performed during IVF to screen embryos for specific genetic conditions and chromosomal abnormalities prior to implantation.

    Understanding Preimplantation Genetic Testing

    Preimplantation Genetic Testing (PGT) is an advanced procedure performed during the IVF process to evaluate embryos for chromosomal abnormalities and inherited genetic conditions before they are transferred to the uterus.

    At Hope Fertility, our embryology and genetics team uses state-of-the-art technology to help you build your family with greater confidence and peace of mind.

    Three Main Types

    Types of PGT

    There are three main types of PGT, each designed to screen for different genetic concerns:

    01

    PGT-A (Aneuploidy Screening)

    Detects chromosomal abnormalities (extra or missing chromosomes)

    02

    PGT-SR (Structural Rearrangements)

    Identifies chromosomal structural issues such as translocations

    03

    PGT-M (Monogenic Disorders)

    Tests for specific inherited genetic diseases

    This testing allows your fertility team to select embryos with the highest potential for a healthy pregnancy.
    Is PGT Right for You?

    Who Should Consider PGT?

    PGT may be recommended for patients undergoing IVF who have:
  1. A known genetic disorder in the family
  2. Advanced maternal age
  3. Recurrent pregnancy loss (recurrent miscarriage)
  4. Previous IVF failures
  5. Concerns about chromosomal abnormalities
    6. Our specialists provide personalized fertility evaluations in Atlanta to determine if PGT is appropriate for your situation.

    The Process

    How PGT Works During IVF

    PGT is seamlessly integrated into the IVF process:

    01

    Embryo Creation

    Embryos are created through IVF in our advanced laboratory.

    02

    Embryo Biopsy

    A small number of cells are biopsied from each embryo by experienced embryologists.

    03

    Genetic Analysis

    The samples are analyzed in a specialized genetics laboratory for chromosomal and genetic health.

    04

    Embryo Classification

    Embryos are classified based on genetic health, and a selected embryo is transferred in a future cycle.

    This process allows for careful selection of embryos prior to implantation.
    Advantages

    Benefits of PGT

    PGT may offer several important advantages for patients undergoing IVF:
  6. Increases the chance of successful implantation
  7. Reduces the risk of miscarriage
  8. Helps identify genetically normal embryos
  9. Supports informed decision-making
  10. May reduce the number of IVF cycles needed
    11. The primary goal of PGT is to transfer unaffected embryos, improving the likelihood of a healthy pregnancy.

    Chromosomal Analysis

    Can PGT Determine Embryo Sex?

    Yes. PGT can identify the chromosomal sex of an embryo prior to transfer.

    This information may be used for medical reasons, such as avoiding sex-linked genetic conditions, and in some cases for family balancing depending on clinical guidance and regulations.

    FAQ — Preimplantation Genetic Testing

    What is PGT in IVF?

    PGT (Preimplantation Genetic Testing) is a procedure performed during IVF to test embryos for chromosomal abnormalities or genetic conditions before transfer. It helps identify embryos with the highest chance of resulting in a healthy pregnancy.

    There are three main types of PGT: PGT-A screens for chromosomal abnormalities (extra or missing chromosomes); PGT-SR detects structural chromosomal rearrangements; and PGT-M tests for specific inherited genetic disorders.

    PGT can improve implantation rates and reduce miscarriage risk by selecting chromosomally normal embryos. While it does not guarantee pregnancy, it may increase the likelihood of success per embryo transfer.

    PGT may be recommended for patients with advanced maternal age, recurrent miscarriage, known genetic disorders, previous IVF failure, or concerns about embryo quality.

    PGT is considered safe when performed by experienced embryology teams. The biopsy involves removing a small number of cells from the embryo, which typically does not affect its ability to develop.

    Yes. PGT can detect many chromosomal abnormalities and specific inherited genetic conditions, depending on the type of testing performed.

    Yes. PGT can identify the chromosomal sex of an embryo prior to transfer. This may be used for medical purposes or, in some cases, for family balancing.

    PGT can be valuable for patients looking to reduce miscarriage risk, avoid genetic conditions, or improve efficiency by selecting the healthiest embryos. Your fertility specialist will help determine if it is right for you.
