Endometrial scratching is a relatively new, simple technique that provides good results in assisted reproduction techniques.
It is applied mainly in patients diagnosed with recurrent implantation failure to improve the reception site of a new embryo.
The objectives of endometrial scratching are:
- To produce a small lesion in the endometrium that causes growth factors, hormonal and chemical factors to be released, so that the newly growing endometrium becomes more receptive.
- Potential activation of molecular/genetic factors involved in implantation that would not be activated in a normal transfer.
At present, scratching is considered to be a good solution for patients with previous implantation failures in order to increase their gestation rate, although there is still no evidence for its routine recommendation.
