The Endometrial Receptivity Array (ERA) is a diagnostic tool used in In Vitro Fertilization (IVF) to determine the ideal timing for embryo transfer. It essentially pinpoints the precise window within your menstrual cycle when the lining of your uterus (endometrium) is most receptive to an embryo implanting successfully.

Here's a simplified explanation:

Goal: Identify the "window of implantation" (WOI) for your specific body.

Process: During a natural menstrual cycle, a small sample of your endometrium is collected.

Analysis: The sample is analyzed using a genetic chip to assess the activity of genes associated with receptivity.

Result: The test identifies if your WOI aligns with the standard timing used in IVF or if it differs (earlier or later).


Personalization: Tailors embryo transfer timing to your unique biology, potentially improving implantation success.

Reduced risk: May lessen the chance of failed implantation due to timing issues.

Targeted treatment: In case of a non-receptive window, personalized hormone protocols can be implemented.
