The Endometrial Receptivity Array (ERA) test is indicated for women who have experienced repeated implantation failures despite having seemingly normal embryos and a healthy uterus.
Here's a breakdown of why an ERA test may be recommended:
Understanding Implantation Failure
- Implantation is the crucial process where a fertilized egg attaches to the uterine lining (endometrium).
- Implantation failure occurs when this process doesn't happen successfully, leading to a negative pregnancy test.
- Repeated implantation failures can be frustrating and emotionally challenging for couples pursuing IVF treatment.
Why ERA Tests are Helpful
- The ERA test helps identify the optimal window of implantation for each individual woman.
- It analyzes a biopsy sample of the uterine lining to determine its receptivity to implantation at different stages of the menstrual cycle.
- The test results can then be used to adjust the timing of embryo transfer to increase the chances of successful implantation.
When an ERA Test Might Be Recommended
- Multiple failed IVF cycles: If you've had several IVF cycles that haven't resulted in pregnancy, an ERA test can help identify potential timing issues.
- History of recurrent miscarriages: While not the primary indication, an ERA test might be considered if there's a history of miscarriages, especially if they occur early in pregnancy.
It's important to note that the ERA test is not a guarantee of success. It can help identify timing issues, but other factors like embryo quality and overall health can also play a significant role in pregnancy outcomes.
