Houston PGT

Rooted in Care, Guided by Science.

Preimplantation Genetic Testing (PGT) is an advanced laboratory technique used during in vitro fertilization (IVF) to evaluate embryos for specific genetic conditions before transfer. HART Fertility Clinic offers Houston PGT as a carefully considered option for patients who may benefit from additional genetic insight during their fertility journey.

Primary Care Doctor Talking To A Patient

What Is Preimplantation Genetic Testing?

Preimplantation Genetic Testing is performed on embryos created through IVF. After fertilization and several days of development, a small number of cells are gently removed from the outer layer of the embryo. These cells are analyzed to identify chromosomal abnormalities or specific inherited conditions.

Importantly, the portion of the embryo that becomes the fetus is not directly disturbed during biopsy. The sampling is performed by experienced embryologists using precise laboratory techniques. Once IVF genetic testing is complete, embryos identified as chromosomally normal may be selected for transfer.

Types of PGT

There are different forms of IVF genetic testing, depending on clinical needs:

PGT-A

Preimplantation Genetic Testing for Aneuploidy

PGT-A screens embryos for the correct number of chromosomes. Chromosomal imbalances can increase the risk of miscarriage or unsuccessful implantation. PGT-A is often considered for patients of advanced maternal age or those with recurrent pregnancy loss.

PGT-M

Preimplantation Genetic Testing for Monogenic Disorders

PGT-M is used when one or both parents carry a known genetic mutation associated with a specific inherited condition. This allows embryos to be screened for that condition before transfer.

PGT-SR

Preimplantation Genetic Testing for Structural Rearrangements

PGT-SR may be recommended when one partner carries a chromosomal structural rearrangement, such as a balanced translocation, that could affect embryo development.

Your care team will discuss which, if any, of these IVF genetic testing options are appropriate for your situation.

Letting New Beginnings Take Shape

Houston PGT requires technical expertise and controlled laboratory conditions. Our embryology team follows strict protocols for embryo biopsy and cryopreservation. Genetic samples are sent to specialized laboratories for analysis, and results are reviewed in coordination with your physician.

Preimplantation Genetic Testing FAQ

What is Preimplantation Genetic Testing (PGT)?

PGT is a laboratory procedure performed during IVF that evaluates embryos for specific genetic or chromosomal conditions before transfer. A small sample of cells is analyzed to help identify embryos that may have the correct chromosomal structure.

How is PGT performed?

After embryos develop in the lab for several days, a few cells are gently removed from the outer layer. The embryos are then frozen while the cells are sent for genetic analysis. Results guide embryo selection for transfer.

What is the difference between PGT-A and PGT-M?

PGT-A screens embryos for chromosomal number abnormalities, while PGT-M tests for specific inherited genetic conditions. The type recommended depends on medical history, age, and known genetic risks.

Does PGT guarantee a healthy baby?

No. PGT can reduce the risk of transferring embryos with certain chromosomal or genetic abnormalities, but it does not guarantee pregnancy or eliminate all potential health risks.

Who should consider PGT?

PGT may be recommended for patients of advanced maternal age, those with recurrent miscarriage, prior unsuccessful IVF cycles, or individuals carrying known genetic conditions.

Does embryo biopsy harm the embryo?

When performed by experienced embryologists, embryo biopsy is considered safe. The procedure targets cells from the outer layer, which develops into the placenta, not the fetus itself.

Will PGT delay my IVF cycle?

PGT usually requires embryos to be frozen while testing is completed. This means embryo transfer typically occurs in a later frozen transfer cycle rather than immediately after retrieval.

Are all embryos eligible for testing?

Not all embryos reach the developmental stage required for biopsy. Only embryos that meet certain quality and growth criteria are considered suitable for genetic testing.

How accurate is PGT?

PGT is highly advanced and reliable for detecting specific chromosomal or genetic conditions. However, no test is 100 percent perfect, and results are interpreted within the full clinical context.

Is genetic counseling recommended with PGT?

In many cases, yes. Genetic counseling can help patients understand testing options, interpret results, and make informed decisions based on medical history and family considerations.

Where Possibility Begins to Blossom

PGT is highly advanced but not absolute. While testing significantly reduces the likelihood of transferring embryos with certain chromosomal abnormalities, no test can eliminate all risks.

Patients should understand that:

PGT does not guarantee implantation or live birth.

Not all embryos may qualify for biopsy.

Some embryos may not return normal results.

Genetic testing results must be interpreted within the context of overall clinical findings.

The goal of Houston PGT is not to guarantee pregnancy but to provide additional information that may improve embryo selection and reduce certain risks. Our team discusses potential benefits and limitations openly so you can make an informed decision.
