IVF Embryo Grading/Evidence
Method evidence record

IVF Embryo Grading

IVF Embryo Grading is a standardized morphological assessment system for evaluating the quality and viability of embryos in assisted reproductive technology. First formalized by Gardner and colleagues in 1999, it uses microscopic examination to score embryos across multiple criteria, enabling clinicians to select the most viable embryos for transfer and improve pregnancy outcomes.
