Endometrial scratch

Nidation curettage: 'Scratching' the uterus lining

Stimulation by "scratching" the endometrium prepares the uterus best for an embryo or blastocyst transfer. The effectiveness of this method, known as nidation curettage or endometrial scratching, has now been proven in various studies. We perform endometrial scratching in our TFP fertility clinics as part of IVF or ICSI treatments. Our doctors will be happy to advise you on the procedure and the prospects of success in your individual case.

Think of it like a seed; seeds have more chance of growing if planted in a slight groove in the ground, rather than just landing on unprepared soil.

When to do a nidation curettage?

The best time to undergo a nidation curettage is in the first half cycle for an assisted reproductive technologies attempt (the effect lasts for two months – so when the IVF is not carried out straight away in the next cycle, it is also not a problem).

The procedure is particularly effective after an unsuccessful implantation. It can however also be carried out before the first IVF attempt.

It makes good sense to combine the nidation curettage in the cycle prior to IVF with a nidation rinse, in particular in the cases of unsuccessful prior attempts.

The endometrial scratch procedure

This scratching effect can be achieved by a small "micro-curettage". This is a small procedure that can be carried out at the clinic without anaesthesia. A small “tube” (called a Pipelle®) is inserted into the uterus which makes this “roughening” of the uterine lining. The procedure takes approximately ten minutes and is mostly pain-free. You are able to leave the clinic immediately after the procedure.

To which patients is endometrial scratching recommended?

An insufficient build-up of the endometrium can in some cases be the cause of unsuccessful IVF. The usefulness of implantation curettage depends on the individual case and should be discussed in detail on the basis of the preceding diagnostics. In our fertility clinics, we recommend treatment if implantation does not occur even after repeated blastocyst transfers - without other medical reasons for the failure of artificial insemination being apparent.

Are there any risks?

According to the current state of knowledge, there are no known risks of implantation curettage for the patient or the embryo. Of course, our experienced doctors will take the time to explain the treatment to you in detail. Simply contact us - we look forward to hearing from you!
