Surrogacy and preimplantation genetic testing: A closer look


Introduction to Surrogacy and Preimplantation Genetic Testing (PGT)

Surrogacy is a reproductive option that allows individuals or couples to have a child through the assistance of a surrogate mother. Preimplantation Genetic Testing (PGT) is a specialized technique used during the in-vitro fertilization (IVF) process to screen embryos for genetic abnormalities before they are implanted. When surrogacy and PGT intersect, it can provide additional reassurance and options for intended parents. This article takes a closer look at the role of PGT in surrogacy.

Understanding Preimplantation Genetic Testing (PGT)

PGT involves the genetic analysis of embryos created through IVF before they are transferred to the surrogate's uterus. It can provide valuable information about the genetic health of the embryos, helping to reduce the risk of passing on certain genetic disorders to the child.

There are two main types of PGT:

  1. Preimplantation Genetic Testing for Aneuploidy (PGT-A): This type of testing screens embryos for numerical chromosomal abnormalities. PGT-A helps identify embryos with the correct number of chromosomes, reducing the chances of implanting embryos with abnormalities that may result in failed implantation or miscarriage.
  2. Preimplantation Genetic Testing for Monogenic Disorders (PGT-M): PGT-M is performed when there is a known genetic disorder in the intended parents. This testing allows for the identification of embryos that do not carry the specific genetic mutation or disorder, increasing the chances of a healthy pregnancy and child.

Role of PGT in Surrogacy

Intended parents pursuing surrogacy may choose to incorporate PGT into the process for several reasons:

  1. Genetic Screening: PGT provides an opportunity to screen embryos for potential genetic disorders or abnormalities, which can help reduce the risk of passing on inherited conditions to the child.
  2. Improved Pregnancy Success: PGT-A can help identify chromosomally normal embryos, increasing the chances of successful implantation and reducing the risk of miscarriage.
  3. Medical Decision-Making: PGT-M allows intended parents to select embryos that do not carry specific genetic mutations, giving them peace of mind and the ability to prevent the transmission of certain genetic disorders to their child.

Considerations and Limitations

It's important to recognize that PGT is not a guarantee of a healthy pregnancy or a genetically perfect child. The technology has limitations, and there can be false-positive or false-negative results. Additionally, PGT cannot screen for all genetic conditions or guarantee the absence of spontaneous genetic mutations during embryonic development.

Intended parents should consult with fertility specialists and genetic counselors to understand the specific benefits, limitations, and ethical considerations associated with PGT in the context of their surrogacy journey.
