Patients with endometritis who are considering IVF must first treat the endometritis. As we all know, the endometrium is the soil for embryo development. If the inflammation is severe, even with IVF, the transferred blastocysts are likely to fail to implant. Endometritis can significantly affect the implantation of the fertilized egg, and after implantation, it may lead to increased risks of miscarriage, placenta previa, and a higher incidence of adhesive placenta. Therefore, if IVF is to be performed, it is imperative to treat the inflammation of the endometritis. Once the treatment is successful, the embryo will not be affected during IVF.
