ERA (Endometrial Receptivity Array ) Test in IVF Treatment

| 23 Jun 2023 | 2298 Views |

The What, Why, and How of ERA Test

Endometrial Receptivity Array (ERA), in layman’s terms, is a specialized genetic test that helps us understand the “talk” between an embryo and a woman’s uterus. The primary purpose of ERA is to find out the optimal time or the “receptive period” when the uterus is ready to accept an embryo.

1. What is the ERA Test in IVF?

ERA test is a game-changer in the IVF field. It comes in handy when couples experience multiple failed IVF attempts. By determining the “window of implantation,” ERA enhances the chances of successful pregnancy.

2. Why is ERA Test Necessary?

Despite having top-quality embryos, some couples face repeated IVF failure. This situation often arises due to a timing mismatch between the embryo ready to implant and the uterine lining’s receptivity. That’s where ERA steps in!

3. How is the ERA Test Procedure Conducted?

This procedure is similar to an endometrial biopsy. The IVF specialist obtains a small sample of endometrial tissue, which is then analyzed to identify the “receptive” phase.

Benefits, Success Rates, and FAQs of ERA Test

Benefits of ERA Test:

  • Precise detection of the implantation window
  • Enhanced chances of successful pregnancy
  • Reduced risk of implantation failure

ERA Success:

ERA test has shown a promising success rate in the IVF journey. As per studies, the live birth rate is significantly higher in patients who had ERA-guided embryo transfer compared to those who had not1. Some studies have shown that in women who have 3 or more IVF failures, displaced window of implantation is seen in upto 27.5% of patients and these patients can be benefitted from ERA.

Delving Deeper: Understanding Endometrial Receptivity

Endometrial Receptivity refers to the period when the endometrium (the inner lining of the uterus) is prepared to accept an embryo for attachment and growth. This period, often referred to as the “window of implantation,” is crucial for a successful pregnancy following IVF treatment. Identifying this window accurately is a game-changer, and that’s precisely what the ERA Test accomplishes.

Decoding ERA Test Results and Celebrating ERA Success at India IVF Fertility

1. Understanding ERA Results:

ERA results are typically classified as “Receptive” or “Non-Receptive”. A “Receptive” result implies that the endometrium was ready for implantation during the biopsy time. Conversely, a “Non-Receptive” result means that the window of implantation was either before or after the time of the biopsy. The beauty of ERA is its ability to provide a personalized embryo transfer timeline, enhancing the odds of a successful pregnancy.

2. Celebrating ERA Success:

Here at India IVF Fertility, we’ve witnessed numerous success stories where the ERA Test has played a crucial role. This test has been pivotal in our mission to bring joy to families, particularly for those with a history of failed IVF attempts.
