Achieving a successful embryo transfer is one of the main objectives in assisted fertility treatments. However, finding the exact moment for the embryo to implant in the uterus is an art.
To facilitate the process, the ERA (Endometrial Receptivity Array) Test has emerged as a key tool to optimize the chances of success in in vitro fertilization (IVF). This test allows you to determine precisely when is the best time to perform the embryo transfer, personalizing the treatment according to the unique needs of each person.
The ERA Test offers an innovative solution for those looking to maximize their chances of pregnancy. By identifying the ideal time for embryo implantation, this test has marked a before and after in reproductive medicine, becoming an essential option for those who want to achieve pregnancy with as few attempts as possible.
What is the ERA Test?
The ERA Test is a diagnostic test designed to assess the receptivity of the endometrium, which is the inner layer of the uterus where the embryo must implant to give rise to pregnancy. Through the genetic analysis of a small sample of endometrial tissue, the test identifies the most suitable period for embryo transfer, known as the implantation window. Keep in mind that this time window varies for each person.
The analysis is based on the expression of more than 200 genes related to endometrial receptivity, which allows us to know with great precision whether the uterus is ready to receive the embryo. In this way, the ERA Test adjusts the transfer schedule according to the particular characteristics of the endometrium, avoiding time loss and reducing the number of failed attempts.
How is the ERA Test performed?
The procedure for performing the ERA Test follows a series of carefully planned steps to ensure accurate results:
- Endometrial preparation: The medical team simulates a cycle of hormonal treatment, preparing the endometrium in a similar way as it would be done for a conventional embryo transfer.
- Endometrial biopsy: Once the endometrium has reached the appropriate stage, a small biopsy is performed to obtain the necessary sample. This procedure is outpatient and brief, although it may cause mild discomfort.
- Genetic analysis: The endometrial tissue sample is sent to a specialized laboratory, where genes related to endometrial receptivity are analyzed to determine the optimal implantation window.
- Results report: The results allow the specialist to adjust the embryo transfer schedule based on the information obtained, customizing the treatment to improve the chances of success.
Why is the ERA Test the ideal solution for embryo transfers?
The ERA Test has proven to be an effective tool for resolving implantation problems that were previously difficult to diagnose. Its benefits include:
- Personalisation of the treatment: The test allows the specific implantation window to be identified for each person, ensuring that the embryo transfer is carried out at the most appropriate time.
- Increased success rate: By determining the optimal period for implantation, the ERA Test increases the chances of achieving a successful pregnancy, especially in those cases where implantation has been a challenge.
- Reduction of previous failures: For those who have experienced several failed attempts at fertilization, the ERA Test offers a solution by identifying endometrial receptivity problems that might have gone unnoticed in other treatments.
- Avoids waste of time and resources: By performing the transfer at the right time, the need for repeat procedures is reduced, which implies greater efficiency in terms of time, effort and costs.
When is the ERA Test recommended?
Although not everyone who goes through fertility treatment needs to take an ERA test, there are some specific situations in which this test is particularly useful:
- Unexplained problems in fertilization treatments: When no clear cause for failures in fertilization treatments has been identified, this test can offer new answers.
- In vitro fertilization in people with unique characteristics: Every body is different, and the ERA Test can customize the strategy in people who require a different approach.
Once the analysis and interpretation of results has been carried out, the fertility specialist will have a clear view of the endometrium’s receptivity status. These results may indicate whether the endometrium is receptive at the time the biopsy was performed or if an adjustment in the timing of the embryo transfer is required. In some cases, the report will reveal a displaced implantation window, allowing treatment to be tailored precisely to increase the chances of implantation.
The ERA Test has established itself as a reliable tool to improve success rates in in vitro fertilization treatments, offering an effective and evidence-based alternative for those seeking to conceive. Its ability to identify the exact moment of implantation has made this test a fundamental piece within modern reproductive medicine.
At Fertivida, we understand the importance of personalizing each fertility treatment to maximize the chances of success, which is why we offer the ERA Test as part of our advanced diagnostic services.
