Although the heterogeneous body of data on the subject deserves further clarification. In summary, it was found that unselected subfertile women generally benefit less from endometrial scratching, but scratching appears to be successful in women who have experienced repeated implantation failure. The studies were divided according to whether the women suffered from recurrent implantation failure or not. The current literature was examined to investigate if there was any possible benefit from endometrial scratching. Scratching the endometrium prior to embryo transfer has been suggested as one means of enhancing the likelihood of implantation.
In the treatment of sterility, many approaches have been used to overcome the barrier of implantation failure and improve the chances of successful nidation. Failure of implantation may occur repetitively. Many causes of sterility can be overcome with the aid of in vitro fertilization, but successful implantation of the embryos is the major limiting factor. Assisted reproduction procedures are currently the treatment of choice for a number of patients who desire children. About one in every six couples is affected by sterility.
