However, there is no known single morphological charcteristic available to enable a simple method for embryo viability assessment. Different grading methods have been developed and utilized in selecting embryos for transfer (6-14). The necessity of developing a unifying standard method of grading and reporting embryo quality as acceptable to all has long been recognized. The embryologists under the banner of SART (Society for Assisted Reproductive Technology) took the initiative by including embryo quality in the SART data base, establishing an embryo grading system that uses a uniform grading method The necessity of such a unifying embryo grading method has also been felt by the international community. The European embryologists are working toward adopting an embryo classification system of the present study was to see if the SART grading system can be improved upon and whether it can have wider application in the field of ART. Our study found the SART method to be full of potential to become an international standard of embryo viability assessment by showing how to make it more efficient and applicable to all developmental stages of a developing embryo. |
