ERPeakSM Endometrial Receptivity Test

Helps you identify the optimal time for embryo transfer
during an IVF cycle

The endometrium plays an important role in the control of human embryo implantation.
The ERPeak endometrial receptivity test offers accurate and reliable detection of the receptivity status of a woman’s endometrium. Transferring an embryo when the endometrium is at its best quality (known as the window of implantation) helps to increase the chances of successful implantation.

Why test for endometrial receptivity status?

The Window of Implantation (WOI) is the short time period during which the endometrium is ready to accept an embryo, i.e. is receptive, for implantation.

This is typically five days after progesterone exposure in an assisted reproduction treatment cycle.

In approximately 30% of women, though, the WOI is shifted, occurring either earlier or later than five days after progesterone exposure.²

First clinical outcomes after personalized embryo transfer using the new endometrial receptivity test in recurrent implantation failure patients

First clinical results from personalized embryotransfer using our ERPeak endometrial receptivity test shows an improvement in pregnancy outcomes for recurrent implantation failure group. The study by Ohara et al, at the Reproduction Clinic Osaka and Reproduction Clinic Tokyo shows women with a displaced window of implantation (WOI) have comparable pregnancy outcomes to women who didn’t have a displaced WOI, regardless of age when using ERPeak.

*Implantation rate was lower than pregnancy rate as some patients had more than one transfer

How it works

CooperGenomics’ ERPeakSM test measures the expression of relevant hormone-regulated genes allowing us to determine when a patient’s window should occur, thereby informing the physician of the most suitable time for embryo transfer to increase the likelihood of achieving pregnancy.

Studies have shown a 51.7 – 63.2% pregnancy rate in patients with recurrent implantation failure (RIF) who have undergone endometrial receptivity testing.3,4

Easy result interpretation

ERPeakSM test results are reported as not-receptive, pre-receptive, receptive,
post-receptive or no result. CooperGenomics will also recommend a time for transfer in cases with pre- or post-receptive results.
