A question often asked by families considering embryo adoption is whether they should limit their preferences to embryos that have undergone Preimplantation Genetic Testing for Aneuploidy (PGT-A).
PGT-A is a screening test that assesses embryos for potential chromosomal abnormalities before implantation, which can provide useful information regarding the viability of an embryo. Many fertility specialists advocate for the use of PGT-A, as it can help identify chromosomal errors, which could lead to miscarriage or health issues in a resulting child. However, it is important to note that PGT-A is not a definitive assessment of an embryo’s overall health.
Embryos that have not undergone PGT-A testing can and do successfully develop into healthy babies. Some embryo donors did not have their embryos tested because the technology was not as advanced at the time of their IVF cycle, or there was no specific reason to test them. This raises an important consideration for embryo adoptive families: PGT-A is a screening test, not a diagnostic one.
As with any screening tool, PGT-A has limitations and can produce inaccurate results, meaning some embryos that may appear abnormal could actually result in a healthy child if given the chance. This is why some embryo donation or adoption programs do not allow families to express a preference for receiving PGT-A tested embryos.
The decision of whether to prioritize PGT-A results when selecting embryos is highly personal and can depend on a variety of factors. Families should weigh their own fertility history, medical concerns, and emotional readiness when considering the role of PGT-A in their decision-making process. Understanding these factors can help families make a more informed decision as they navigate the complex world of embryo adoption.
1. One of the key considerations for families is their fertility diagnosis.
For couples or individuals who have experienced recurrent pregnancy loss, PGT-A testing may offer some peace of mind. The screening can reduce the likelihood of selecting an embryo with chromosomal abnormalities, which may decrease the risk of miscarriage. However, it is important to note that as of 2022, research has not shown that PGT-A testing significantly increases the chances of pregnancy success compared to non-tested embryos. This means that, while the screening can provide reassurance in some cases, it may not be necessary for every family.
2. Another important consideration is emotional resilience.
Embarking on the embryo adoption journey can be emotionally challenging, and families need to assess their readiness for potential ups and downs. Some may prefer the added assurance that comes with PGT-A tested embryos, hoping that it will lead to a smoother experience. Others, however, might prioritize factors like compatibility with the donor or the timing of the embryo transfer over whether the embryos have been genetically tested. Every family’s journey is unique, and emotional readiness plays a key role in determining what factors to prioritize.
3. When it comes to compatibility with potential donors, other aspects beyond PGT-A results can play a role in the decision.
Factors such as the age of the donor at the time of IVF, the quality of the embryos, and any prior transfer outcomes can all provide valuable information about the likelihood of success. For some families, these characteristics may serve as an acceptable compromise in place of PGT-A testing. The decision is often less about choosing between tested and non-tested embryos, and more about evaluating the overall circumstances and finding the right match.
4. Family-building goals, including desired family size, are also critical to consider.
If a family is hoping to have multiple children, they might prefer larger embryo cohorts or PGT-A tested embryos to align with their long-term goals. However, it’s important to recognize that larger sets of embryos are often not genetically tested. Families need to decide what matters most to them in their journey: having more embryos available or ensuring that the embryos they select have undergone genetic screening.
Ultimately, the decision to prioritize PGT-A tested embryos comes down to balancing several factors, including medical history, emotional preparedness, and family-building aspirations.
Every family’s path to embryo adoption is deeply personal, and there is no one-size-fits-all answer. Consulting with medical professionals, mental health experts, and embryo adoption and donation programs can help families gather the information they need to make an informed decision.
