Endometrial scratch

Written by Zayn Miah & R KhanomLast updated 17 September 2026Not clinically reviewed

A procedure involving a small deliberate injury to the womb lining, done before an embryo transfer cycle, intended to encourage implantation.

In plain English

It's a small deliberate scratch of the womb lining, done ahead of a transfer, in theory to trigger a helpful healing response.

Why it matters

The HFEA rates this as an add-on with no consistent evidence of improving live birth rates for most patients, so it's not something to assume will help.
