Endometrial Receptivity Analysis(ERA)
procedureDefinition
A biopsy-based test of endometrial tissue sometimes used to evaluate whether transfer timing may need adjustment.
In IVF Treatment
ERA involves a mock transfer cycle with a biopsy taken at the standard transfer window. The results may classify the sample as standard, pre-receptive, or post-receptive, which some clinics use when considering a timing adjustment. Its benefit is debated, and it is not a guarantee of implantation.
Frequently Asked Questions
Should I do an ERA test?
ERA is generally considered only after repeated transfers with good-quality embryos when no other cause is found. For a first transfer, most clinics do not routinely require it. Ask your clinic how they interpret the evidence for your situation.
