Endometrial Receptivity Array – ERA Fertility Treatment

Optimizing Implantation Timing for Higher IVF Success Rates

What is ERA - Endometrial Receptivity Array?

The Endometrial Receptivity Array (ERA) is an advanced genetic test designed to determine the optimal timing for embryo transfer during an IVF cycle. This test evaluates the receptivity of the endometrial lining by analyzing the expression of specific genes that indicate when the uterus is most prepared for implantation. Since every woman’s implantation window can vary, ERA provides a personalized approach to embryo transfer, significantly improving the chances of a successful pregnancy.

ERA is especially beneficial for women who have experienced repeated IVF failures, unexplained infertility, or conditions affecting the endometrial lining, such as endometriosis or hormonal imbalances. By precisely identifying the implantation window, this test helps fertility specialists time the embryo transfer with greater accuracy, ensuring the highest likelihood of success. At Bud IVF, we integrate ERA into personalized fertility treatment plans to maximize implantation potential and support your journey toward parenthood.

When Should You Consider ERA Testing?

ERA testing is recommended for patients who:

Have Experienced Multiple IVF Failures

If you’ve gone through multiple IVF cycles without success, ERA can help identify whether the timing of embryo transfer may be the issue.

Unexplained Infertility

For couples with no clear reason for infertility, ERA testing can help uncover hidden causes related to the endometrium’s receptivity.

Women with Recurrent Miscarriages

If you’ve experienced multiple miscarriages, ERA can help assess whether your endometrium is optimally prepared to support pregnancy.

Patients with Certain Uterine Conditions

Women diagnosed with endometriosis, fibroids, or polyps may benefit from ERA testing to ensure their endometrial lining is receptive enough for embryo implantation.

Those with Irregular Ovulation or Hormonal Imbalances

If you have hormonal issues that might affect the timing of your natural cycle or IVF, ERA can help pinpoint the best time for embryo transfer.

The Procedure: How Does ERA Testing Work?

The ERA procedure involves a simple biopsy of the endometrial lining. Here’s how it’s done:

01
Pre-Treatment Preparation
Your fertility specialist will synchronize your cycle with hormonal medications to stimulate the endometrium. This prepares the uterus as if it were going to undergo an embryo transfer.
02
Endometrial Biopsy
A small sample of the endometrial tissue is collected via a minimally invasive procedure performed during your IVF cycle. The biopsy is typically done after you’ve been on the required hormone regimen for a certain period, simulating the window of implantation.
03
Genetic Analysis
The biopsy sample is then sent to a specialized laboratory, where it is analyzed to identify the genetic markers that indicate the receptivity of the endometrium. The test will reveal the optimal timing of embryo transfer and whether the uterine lining is ready to support a pregnancy.
04
Results and Consultation
Results are typically available within 10-14 days. Based on the findings, your fertility specialist will work with you to plan your next steps in the IVF process, such as adjusting the timing of embryo transfer.

Helps in Recurrent Miscarriages

ERA can help identify issues that may contribute to repeated miscarriages, improving the chances of a successful pregnancy.

Whether you are facing one or multiple challenges, Bud IVF is here to guide you with personalized care and expert solutions tailored to your unique needs.

Success Rates & Factors Affecting ERA Outcomes

The success rate of ERA testing is high, with a 90% accuracy in determining the optimal implantation window. This precision can significantly improve IVF outcomes, especially for women who have undergone multiple failed cycles. ERA results help identify the most appropriate time for embryo transfer, maximizing the chances of success.

However, there are several factors that can influence the outcome of ERA testing:

  1. Quality of the Endometrial Sample: The accuracy of the ERA test is dependent on the quality of the biopsy sample, so it is essential to work with an experienced fertility clinic.
  2. Hormonal Synchronization: Proper synchronization of the cycle with hormonal medications ensures that the biopsy is taken at the correct time to simulate the window of implantation.
  3. Underlying Health Conditions: Certain health conditions, such as polycystic ovary syndrome (PCOS), endometriosis, or fibroids, can impact the results of ERA and may require additional treatment or modifications in the IVF plan.

Post-ERA Testing: What Happens Next?

After receiving your ERA test results, your fertility specialist will discuss the findings with you and help develop a personalized plan for your IVF cycle. Depending on the outcome, your doctor may suggest adjusting the timing of the embryo transfer, hormone therapy, or other fertility treatments. In some cases, the ERA test may reveal that the optimal implantation window is different from what was initially anticipated, allowing your specialist to fine-tune the IVF protocol for better results.

FAQs

What is an Endometrial Receptivity Array (ERA)?

The ERA is a diagnostic test that evaluates the optimal time for embryo transfer by analyzing the genetic expression of the endometrial lining. It identifies the “receptive window” when the uterus is most likely to accept an embryo for implantation.

ERA is recommended for women who have experienced multiple failed IVF cycles despite having good-quality embryos or those with unexplained implantation failure. It is also useful for women with irregular menstrual cycles or unique uterine conditions.
The ERA test involves a biopsy of the endometrial lining, usually conducted during a mock cycle. The sample is sent to a specialized lab, where it is analyzed for over 200 genes that indicate endometrial receptivity.
By determining the precise timing of the uterine receptivity window, the ERA test allows for personalized embryo transfer (pET). This increases the chances of implantation and successful pregnancy, particularly for women with a shifted implantation window.
The ERA test is minimally invasive, involving a small biopsy of the uterine lining. Some women may experience mild cramping or discomfort during the procedure, but it is generally safe and carries no significant risks.

Our specialists work closely with each patient to optimize these factors, maximizing the likelihood of a successful outcome.
