Understanding PGT-A: A Guide to Preimplantation Genetic Testing for Aneuploidy

At Crescenta Fertility, we are dedicated to helping you achieve your dream of having a healthy baby. One of the advanced tools we use in our fertility treatments is Preimplantation Genetic Testing for Aneuploidy, commonly known as PGT-A. Here’s a comprehensive guide to help you understand what PGT-A is, how it works, and how it can benefit your journey to parenthood.

What is PGT-A?

Preimplantation Genetic Testing for Aneuploidy (PGT-A) is a cutting-edge genetic test performed on embryos created through in vitro fertilization (IVF). The goal of PGT-A is to identify embryos with the correct number of chromosomes, which can significantly enhance the chances of a successful pregnancy and reduce the risk of miscarriage.

Aneuploidy refers to an abnormal number of chromosomes in an embryo. Humans typically have 46 chromosomes, arranged in 23 pairs. An embryo with too many or too few chromosomes is considered aneuploid. These chromosomal abnormalities can lead to implantation failure, miscarriage, or genetic disorders.

How Does PGT-A Work?

• IVF Process: The journey begins with IVF, where eggs are retrieved from the ovaries and fertilized with sperm in the laboratory to create embryos.
• Embryo Biopsy: Once the embryos reach a certain stage of development, usually at the blastocyst stage (day 5 or 6 after fertilization), a small number of cells are carefully removed from each embryo. This process is known as an embryo biopsy.
• Previous Cancer Treatments: Genetic Analysis: The cells collected during the biopsy are then analyzed in a specialized genetic laboratory. This analysis checks for chromosomal abnormalities and ensures that the embryos have the correct number of chromosomes.
• Embryo Selection: Based on the results of the genetic analysis, the embryos that are chromosomally normal (euploid) are selected for transfer. This helps in choosing the embryos with the highest potential for a successful implantation and healthy pregnancy.

Why Consider PGT-A?

• Increased Pregnancy Success: By selecting embryos with the correct number of chromosomes, PGT-A can improve the chances of a successful pregnancy and reduce the risk of implantation failure.
• Reduced Risk of Miscarriage: Identifying and transferring euploid embryos can decrease the likelihood of miscarriage, which is often associated with chromosomal abnormalities.
• Personalized Treatment: PGT-A allows for a more tailored approach to fertility treatment, ensuring that you have the best possible chance of a successful outcome.
• Family Planning: For those with a history of recurrent miscarriage or failed IVF cycles, PGT-A offers valuable insights that can help guide your fertility treatment decisions.

Who Can Benefit from PGT-A?

PGT-A is particularly beneficial for:

• Women of Advanced Maternal Age: Women over 35 may have a higher risk of chromosomal abnormalities in their embryos, making PGT-A a valuable tool.
• Couples with Recurrent Miscarriages: If you have experienced multiple miscarriages, PGT-A can help identify embryos with the best chance of a successful pregnancy.
• Couples Undergoing IVF: If you are undergoing IVF, PGT-A can enhance the effectiveness of the treatment by selecting the healthiest embryos for transfer.

What to Expect During the PGT-A Process

• Consultation: Your fertility specialist will discuss the option of PGT-A with you, explaining the benefits and how it fits into your overall treatment plan.
• IVF and Biopsy: You will undergo the IVF process, and if appropriate, the biopsy will be performed on your embryos.
• Results and Decision-Making: Once the genetic analysis is complete, you will receive the results and discuss with your specialist which embryos are suitable for transfer.
• Embryo Transfer: The selected euploid embryos will be transferred into your uterus, with the goal of achieving a successful pregnancy.
