Endometrial Scratching

What is endometrial scratching?

We are able to offer a treatment called endometrial scratching to try and help your embryo(s) implant by improving the endometrial receptivity. This is achieved by “scratching” your endometrial lining before you start your IVF cycle.

Who may benefit from endometrial scratching?

If you have had good quality embryo(s) transferred on at least 2 occasions with no pregnancy resulting we may suggest that you would benefit from this procedure.

How does scratching help implantation?

There are thought to be two ways that scratching might help your embryo(s) implant: (a) certain genes important in preparing the endometrium for pregnancy become “switched on”, and (b) immune cells in the uterus which help implantation increase in number. These help make the lining more receptive to any embryo(s) that are transferred.

When is it done?

The best time to perform endometrial scratching is 7-14 days before the start of your treatment cycle (around the time down-regulation is commenced).

What is involved?

The procedure is quick and simple and should take no more than 15 minutes. The endometrium (lining of the uterus) is gently “scratched” using a disposable sterile instrument, passed through the cervix.

How successful is endometrial scratching?

Endometrial scratching is a relatively new technique and as such we do not have sufficient data to provide success rates at this centre. Clinical trials at other units suggest improved outcomes for women with previous failed treatment cycles.

There is an additional charge for this procedure – please see our Prices

Pipelle for Pregnancy (PIP) study at Bath Fertility

Bath Fertility is participating in the international PIP study initiated by the University of Auckland. The study aims to evaluate whether or not endometrial sampling (otherwise known as endometrial scratch) increases the chance of pregnancy and live birth in women undergoing IVF treatment.

Eligible women who consent to participate in the PIP study will be randomised to either the procedure group or the no procedure group. There is a 50/50 chance that women will be randomised into either group – participants are not able to choose or change the allocation. It is free to participate in the study and women are free to withdraw their consent at any time.

Women who are randomised to undergo the endometrial pipelle procedure will be scheduled for a 10-20 minute appointment in the fertility clinic approximately one month before the planned date of embryo transfer.

For more information please see our leaflet
