This is a rather controversial topic as there are some conflicting evidence to suggest that it does while others show no evidence as such.
Having said that, looking at the general overall consensus, the general feeling among gynaecologists is that it is not possible to say with any confidence whether endometrial scratching can increase the probability of pregnancy for natural intercourse or IUI (intrauterine insemination).
As for endometrial scratching in IVF, there is some evidence to suggest that endometrial scratching performed between day 7 of the previous cycle and day 7 of the embryo transfer (ET) cycle is associated with an improvement in pregnancy rates in women with more than two previous embryo transfers.
There is no evidence of an effect on miscarriage, multiple pregnancy or bleeding. The procedure is associated with some mild discomfort.
