The Role of Genetic Screening

Genetic screening plays a crucial role in the process of surrogacy, ensuring the health and well-being of both the child and the surrogate. By undergoing genetic screening, potential risks and complications can be identified early on, allowing for informed decisions to be made.

Genetic screening is defined as “the process of testing a population for a genetic disease in order to identify a subgroup of people that either have the disease or the potential to pass it on to their offspring.” (1)

Preimplantation Genetic Testing (PGT)

Preimplantation Genetic Testing (PGT) is a series of tests that can be performed on embryos created via in vitro fertilization (IVF) to genetically analyze the embryos prior to transfer. PGT testing can give comfort to surrogates and Intended Parents that the embryo selected for transfer has the correct number of chromosomes, thereby reducing the chances of a failed IVF cycle and reducing the possibility of miscarriage. That said, it is not foolproof, there are many factors for a successful embryo transfer resulting in a live birth.

The process of Preimplantation Genetic Testing begins after eggs are retrieved and fertilized with sperm in the lab where the embryologist will obtain cells for testing. When the embryo reaches the blastocyst stage, a few of the cells on the outside of the embryo are biopsied and sent for genetic analysis. (2)  

Why is this important?

In surrogacy arrangements, genetic screening helps to assess the genetics of the created embryo, reducing the likelihood of genetic disorders being passed on to the child and reducing risk of miscarriage. This proactive approach not only safeguards the unborn child’s health but also promotes a positive and supportive environment for all parties involved.

Furthermore, PGT and Genetic Screening when going through IVF and during your surrogacy journey can offer peace of mind to everyone involved, reassuring them that the process is being carried out responsibly and ethically. Stronger Together Surrogacy advocates for embryos to have PGT. By prioritizing and advocating for genetic screening, you will have a positive and more successful experience when embarking on this extraordinary path to parenthood!
