Endometrial receptivity array

It's a diagnostic test used in the field of reproductive medicine to assess the receptivity of the uterine lining for embryo implantation.


The endometrial receptivity array (ERA) is a diagnostic test used in the field of reproductive medicine to assess the receptivity of the uterine lining (endometrium) for embryo implantation. It helps determine the optimal timing for embryo transfer in in vitro fertilization (IVF) or other assisted reproductive techniques.

The ERA test involves taking a small biopsy of the endometrial tissue lining the uterus. The biopsy is usually performed in a woman’s natural menstrual cycle or in a controlled hormone replacement cycle, depending on the specific protocol used by the fertility clinic. The biopsy sample is then analyzed to assess the gene expression profile of certain markers related to endometrial receptivity.

Here is an overview of the ERA process:

  1. Biopsy Procedure: The endometrial biopsy is typically performed in an outpatient setting. It involves the insertion of a thin catheter through the cervix into the uterus to obtain a small tissue sample from the endometrium. The procedure may cause mild discomfort or cramping, similar to menstrual cramps.

  2. Sample Analysis: The endometrial tissue sample is sent to a laboratory where the gene expression analysis is performed. The expression levels of specific genes associated with endometrial receptivity are evaluated. This analysis helps determine if the endometrium is in the receptive state for embryo implantation or if it requires adjustments in the timing of embryo transfer.

  3. Personalized Timing Assessment: Based on the gene expression analysis, the results of the ERA test will indicate whether the endometrium is receptive or non-receptive at the time of the biopsy. If the endometrium is found to be non-receptive, the test can help identify the optimal window of implantation, which may be shifted compared to the standard timing.

  4. Adjusted Embryo Transfer: With the information obtained from the ERA test, the timing of the embryo transfer can be personalized and adjusted accordingly. This can improve the chances of successful implantation and pregnancy.

The ERA test is typically recommended for women who have experienced repeated implantation failure in previous IVF cycles or for those with unexplained infertility. It allows fertility specialists to individualize the timing of embryo transfer based on the specific needs of each patient.

It’s important to note that the ERA test is still a relatively new diagnostic tool, and further research is being conducted to establish its effectiveness and determine the specific patient populations that may benefit the most from it. It is advisable to consult with a fertility specialist or reproductive endocrinologist to discuss whether the ERA test is appropriate for your specific situation and to understand its potential benefits and limitations.
