- ERA is recommended for patients who have experienced two or more two to three implantation failures, despite good quality frozen embryos. This is largely due to an inhospitable uterine environment, evidenced in about a quarter of such implantation failures. Those seeking to understand their personalized window of implantation better may also opt for such testing.
- In some cases, it may be even suggested for those with a frozen embryo and haven’t yet tried a frozen transfer. This is a pre-emptive method of having failed IVF cycles.
- It may also be recommended to couples who only have a few frozen embryos, even if they have not failed a frozen transfer yet.
- It is also recommended to couples who have done Pre-Implantation Genetic Testing (PGT) on their embryos.
