Question 1

What is an ERA or Endometrial Biopsy used for?

Accepted Answer

If you have experienced repeated IVF transfer failures with good embryos, an Endometrial Biopsy or ERA helps us check for hidden inflammation and pinpoints the exact day your uterine lining is most receptive to an embryo.

Question 2

Is an ERA test painful?

Accepted Answer

It feels similar to an endometrial biopsy or a Pap smear — a brief cramping sensation during the sample collection, which resolves quickly. No anaesthesia is needed.

Question 3

When is ERA testing done in the cycle?

Accepted Answer

It is done in a mock cycle that mimics your actual embryo transfer protocol, so the endometrial lining is prepared exactly as it would be for a real transfer.

Question 4

How many embryo transfer failures before an ERA is recommended?

Accepted Answer

Typically after two or more transfers of good-quality embryos have failed to implant, since ERA is a targeted test rather than a routine first step.

Question 5

Does the ERA result change with every cycle?

Accepted Answer

No, the receptive window identified by ERA is generally stable for that patient and is used to plan future transfers without repeating the test each time.

Question 6

What is checked in an endometrial biopsy besides receptivity?

Accepted Answer

We also screen for chronic endometritis, a low-grade hidden infection that can silently interfere with implantation even when embryos are healthy.
