Does the ERA test actually improve your chance of pregnancy with IVF—or has endometrial receptivity testing been oversold?
Patients often receive completely different advice. Some fertility specialists say the Endometrial Receptivity Analysis, or ERA, can identify a personalized window of implantation. Others say research has proven the test does not work. The truth is more complicated.
In this episode, Dr. Mark Amols revisits ERA in light of newer randomized trials, meta-analyses, and research on recurrent implantation failure. He also examines statements from his earlier episodes—including why he would no longer confidently tell patients that an ERA “cannot hurt.”
Topics include:
- How ERA attempts to identify the window of implantation
- Whether ERA improves live-birth rates during routine IVF treatment
- What the major randomized trial actually found
- Whether that trial was adequately powered
- Why the data do not support ERA before a routine or first embryo transfer
- The unresolved role of ERA after recurrent implantation failure
- Why results differ between untested and euploid embryo transfers
- Whether changing transfer timing could potentially lower success
- Concerns about test accuracy and cycle-to-cycle endometrial variability
- When ERA might still be discussed as an optional, unproven intervention
The current evidence is reasonably clear for the average IVF patient: routine ERA testing does not improve live birth. For patients with repeated implantation failure—particularly after failed euploid embryo transfers—the answer remains uncertain because the adequately powered randomized trial needed to settle the question has not yet been completed.
This episode separates what ERA has been proven to do, what it has been proven not to do, and what fertility medicine still does not know.
