PREIMPLANTATION GENETIC TESTING – PGT-A & PGT-M (Advanced Preimplantation Genetic Diagnosis PGD/PGS)


With the best IVF lab in New York, New York Reproductive Wellness will utilize the newest IVF technology to give you an edge over your infertility. To maximize your chance of conception, various technologies now exist that can genetically diagnose any abnormalities in your embryos. Using Preimplantation Genetic Testing, PGT-A and PGT-M, our skilled NYRW Embryology team can diagnose known genetic abnormalities, significantly improving the pregnancy rates per transfer up to 60%. PGT-A and PGT-M are a huge advantage to families undergoing fertility treatments and IVF. It will give you the highest chance of having a healthy, live-birth baby. In doing so, we can selectively transfer back the embryo you want, allowing for gender selection and family balancing.

Formerly known as PGS (Preimplantation Genetic Screening), PGT-A is an advanced fertility test for Aneuploidy. Just like PGS, it is a test that is performed on the actual embryo itself in order to identify chromosomal abnormalities which might prevent, complicate or harm a pregnancy. Preimplantation Genetic Testing is traditionally safe for your embryos.

PGT-A benefits include:

  • Increase Pregnancy Rates up to 60% per embryo transfer
  • Lower Chances of Miscarriage
  • Prevent Birth Defects and Ensure a Healthy Pregnancy
  • Decreased Risk of Multiple Pregnancies (twins, triplets, etc)
  • Save Money and Time by improving how quickly you become pregnant

PGT-M (Preimplantation Genetic Testing- Monogenic) allows our embryologists to look for genetic mutations and chromosomal abnormalities which could be inherited by your child. Formerly known as PGD (Preimplantation Genetic Diagnosis), PGT-M tests for inheritable genetic mutations that one or both of the parents are known carriers for. It is a single-gene test which may be used when carrier screening or your family history reveals a known genetic disorder like Sickle Cell, Fragile X, Tay-Sachs, and Cystic Fibrosis.

PGT-M Benefits include:

  • Prevention of Autosomal Recessive disorders (like Cystic Fibrosis)
  • Stop X-linked heritable gene conditions (like DucheMuscular Dystrophy)
  • Avoid Autosomal disorders (like Huntington Disease)
  • Ideal for carriers of cancer syndromes (Like BRCA-1 and 2)
  • Recommended if a previous birth had a single-gene disorder
  • HLA Matching (Human Leukocyte Antigen Matching)
  • Gender Selection (Family Balancing)

PGT-SR (Preimplantation Genetic Testing for Structural Rearrangements) is a cutting-edge variation of Preimplantation Genetic Screening which may identify chromosomal abnormalities that appear (translocation, duplication, and deletion). It may also identify normal non-carrier embryos from balanced carriers.

 

Family Balancing (Gender Selection)

Many families feel strongly about the gender of their IVF Babies, and modern technology now allows for gender selection (sex selection) to ensure that your family maintains the balance you wish. Gender Selection is not a stand-alone service, but rather a natural by-product of Genetic Testing. When our embryologists examine the genetic composition and chromosomal make-up of your embryos, they naturally can identify the gender of each. By selecting the healthiest embryo of the desired gender, we perform a single-embryo transfer, allowing us to ensure that your baby is of the gender you desired. While this method is effective, it is not 100% accurate and requires you to have healthy embryos of the gender you wish to transfer during IVF. Using Preimplantation Genetic Testing is the preferred method for Gender Selection over older methods like Sperm Sorting. Sperm sorting uses the basis of weight to identify sperm which contribute a Y-Chromosome (male) versus and X-Chromosome (female). Sperm sorting is inherently inconsistent in results, but is still used in many labs, worldwide.

 

Who should consider genetic testing?

At New York Reproductive Wellness, everyone struggling with fertility and undergoing IVF is recommend to use genetic testing.  This type of test will dramatically increase your chance of becoming pregnant and having a baby during each attempt, ultimately helping you become pregnant, sooner.  More specifically, PGS/PGD is a good option for:

  • Couples with a history of miscarriage
  • Multiple failed IVF cycles
  • Desire to perform family balancing or gender selection
  • Older patients and patients with egg quality issues
  • Couples who are known carriers of genetic diseases

 

The BEST IVF Technology

As part of our dedication to helping you realize your dreams of family, New York Reproductive wellness also recommends Next Generation Sequencing (NGS), the newest form of PGS.  In a similar fashion to Preimplantation Genetic Screening, NGS allows our embryologist to create generalized probes for identifying an unprecedented number of chromosomal abnormalities.  NGS is proven to have the highest accuracy of any genetic test today, faster than PGS, and with more detail in the reports.  This will allow the NYRW team to quickly and efficiently identify any issues, before they grow to be a problem.
