Three in every ten patients with recurrent implantation failure are found to have a displaced WOI when tested1.
Studies have shown that pET embryo transfer in such patients results in pregnancy rates of 73%3.
The ERA test is the only endometrial receptivity test that can identify short windows of implantation that are less than 24 hours in duration, down to 12 hour shifts. This allows reporting of all the clinically relevant categories of endometrial receptivity: receptive, early receptive, late receptive, pre-receptive, and post-receptive. Studies have shown that patients that are late receptive are at 50% risk of a biochemical pregnancy if the embryo was transferred at a standard time4. This highlights the significance of being able to accurately diagnose all categories of receptivity.
In a Randomised Controlled Trial (RCT2) investigating the use of the ERA test from the very first IVF cycle, pET guided by the ERA test resulted in significantly higher:
- Pregnancy rates from the first embryo transfer (72.5%)
- Cumulative pregnancy rates after one year (95%)
- Live birth rates from the first embryo transfer (56.2%)
- Cumulative live birth rates after one year (71.2%)
The ERA test is backed by a further 21 publications, 13 from Igenomix, and 8 external publications.
