However, the literature shows that Non-Surgical Embryo Recovery (NSER) is possible through specific protocols for cervical relaxation (Fonseca et al., 2019. Reprod Fertil Devel, 31:17-26). The cervical ostium may have several classifications: flap, duckbill, rosette, rose, spiral or papilla. This study aimed to assess the influence of cervical ostium anatomy on the difficulty of traversing cervical rings. In conclusion, the current data suggest that the morphology of cervical ostium may have influence on the success of embryo collection by Non-Surgical Embryo Recovery (NSER) technique.
