What is early embryo viability assessment (EEVA)?
Assessment of early embryo viability is all about checking if the embryo can develop into a healthy fetus during the early stages of pregnancy. This procedure is important in yielding successful pregnancies because it helps uncover problems that may hamper the proper development of an embryo. Generally, early embryo viability is inspected through ultrasound scans, blood tests, and genetic testing, among others.
Why is EEVA important?
The early phases of growing embryos are continuously captured by EEVA utilizing time-lapse imaging equipment, typically from Day 1 (fertilization) to Day 3 or Day 5 (blastocyst stage). Its system provides monitoring of certain development stages, which include:
- A multicellular embryo’s formation
- The first cleavage or cell division
- The timing between subsequent cell divisions
The EEVA system analyzes these developmental milestones using complex algorithms to forecast each embryo’s viability based on the stage and quality of its development. Those embryos that meet these ideal time windows and grow at a proper rate are considered to have high potential, while any deviation from this increases the chances of the pregnancy being non-viable.
How is EEVA performed?
Clinicians usually start the early embryo viability screening process with an ultrasound examination to check the embryo and evaluate its general health and growth. Blood work may also be frequently required to measure hormone levels and ensure the pregnancy is progressing as it should. This may also involve recommendations for genetic testing to determine any genetic abnormalities in the developing embryo that might impede viability.
The outcomes of these tests are next utilized to ascertain whether any extra medical care or intervention is required to maintain the pregnancy and guarantee the wellness of the growing embryo. Physicians can maintain a smooth pregnancy and provide the developing fetus the best chance of a healthy birth by spotting prospective problems early on and taking preventive measures.
What are the benefits of EEVA?
The Eeva system has additional benefits, which are detailed below, in addition to its ability to evaluate embryo viability early.
Objective selection process
Because traditional morphology-based embryo selection is subjective, an embryo’s assessment could vary depending on the embryologist doing the evaluation.
However, the Eeva test gives an unbiased evaluation of the embryos using specific algorithmic settings. Thus, by trying to predict the blastocyst developmental potential, Eeva reduces variability in the embryo evaluations performed by an embryologist.
More stable situations
Thanks to the time-lapse method, eggs may be examined under a microscope without needing to be removed from the incubator. This decreases not only the possibility of manual handling errors but also protects the embryo from changes in culture conditions occurring during standard evaluations outside of an incubator.
Otherwise, conventional assessment is limited to a few precise time points during the embryo’s development to avoid removing it from the incubator. Conversely, the time-lapse method enables continuous monitoring of the embryos. Notably, the time-lapse devices provide much more information relative to embryonic development.
Potential reduction in multiple pregnancies
The inclination to transfer a single embryo to the patient is favored since the Eeva system allows one to more confidently select the embryo with the highest developmental potential. This would result in reduced multiple pregnancies, which carry dangers for both moms and their unborn children.
Are there any limitations to EEVA?
Even while EEVA is a useful tool, it is not foolproof. A few limitations are as follows:
- Cost: EEVA may be more expensive to perform than more traditional forms of embryo selection.
- Technical difficulties: EEVA requires certain tools and knowledge for its imaging and analysis methods.
- Individual variation: Different people may have different relationships between the embryo’s quality and implantation’s success.
Is EEVA suitable for everyone?
Many IVF patients can benefit from EEVA, especially those who have had unsuccessful IVF cycles in the past or who have several embryos available for selection. Nevertheless, it might not be required for other IVF cases. The cost-benefit analysis of including EEVA may not always align with the needs of patients whose embryo bank is small.
Especially uses for EEVA could include:
- Poorly prognostic women (older age, less ovarian reserve, etc.)
- Patients with a history of repeated IVF rejection
- Couples that wish to learn more about the quality of their embryos before getting preimplantation genetic testing (PGT)
How does EEVA compare to other embryo selection techniques?
EEVA has a number of benefits compared to conventional techniques like morphological assessment. It offers a more thorough assessment of the quality of the embryo and can spot minute abnormalities that would not be noticeable to the naked eye.
What is the future of EEVA?
With continuous developments in machine learning and artificial intelligence (AI) improving the capacity to forecast embryo viability, the future of EEVA and embryo selection technologies is bright. With the potential to offer even more accurate evaluations shortly, these technologies could decrease the need for multiple transfers and raise the success rates of IVF.
