The ERA test helps assess endometrial receptivity (the readiness of the uterine lining to accept an embryo) and determine the individual “window of implantation,” allowing the selection of the optimal day for embryo transfer and increasing the chances of a successful pregnancy.
According to statistics from the Igenomix laboratory, 3 out of 10 women have a displaced implantation window.
When the endometrium is receptive, it is ready for embryo implantation. Naturally, this occurs around days 19–21 of the menstrual cycle. This period of receptivity is called the window of implantation.
A lack of synchronization between an embryo ready for implantation and endometrial receptivity is one of the causes of repeated implantation failure. The ERA test evaluates the endometrium to determine the optimal day for embryo transfer.
- Women who have had multiple failed implantations despite transferring morphologically good-quality embryos.
- Women who are unable to achieve pregnancy despite having a morphologically normal uterus and normal endometrial thickness.
- Reliable and accurate, as it analyzes gene activity during the implantation phase.
- Increases the chances of a successful outcome.
- Helps determine the optimal day for embryo transfer.
- Hormonal (medication-based) preparation is carried out.
- On the scheduled day, an endometrial biopsy is taken.
- The biopsy sample is placed in a small tube and sent to a laboratory.
- The ERA test is performed in the laboratory.
- Test results are received within 7–14 days, and the embryo transfer is then scheduled.
