What is an ERA – Endometrial Receptivity Analysis?
ERA or Endometrial Receptivity Analysis is a test done to evaluate a woman’s endometrial receptivity (aka how likely an embryo is to stick). The test is performed to help prevent implantation failure by identifying a woman’s unique and optimum “window of implantation.” This allows us at CNY to better time your embryo transfer and achieve a higher chance that your cycle will be a successful one.
What is the benefit of an ERA?
Quite simply, an ERA helps identify the optimal window of implantation thereby giving us greater insight into your endometrial receptivity and the best time to perform an embryo transfer than what ultrasound and bloodwork alone can provide.
Who might benefit from an ERA?
Women who might benefit from having an ERA generally fall under two main categories:
- Clients with repeated implantation failure despite transferring “high quality,” embryos.
- Women who have a morphologically normal uterus and endometrial thickness where it appears the uterus and endometrium are unlikely the problem.
How is an ERA Performed?
An ERA starts with an endometrial biopsy, meaning a small bit of endometrial tissue is removed from your uterus. From this tissue, your RNA will be extracted and analyzed. After it has been analyzed, you will be issued a report which will help CNY plan your embryo transfer.
