简要总结
Endometrial injury performed in a cycle preceding the one for embryo transfer is associated with an increased implantation and pregnancy rate when carried out during the month preceding that of ovulation induction and fresh embryo transfer. However, there is no evidence about the effect of this intervention on the transfer of cryopreserved embryos.
