The Scientific Basis for Utilizing Conventional Embryo Selection Parameters
It is important for the clinical embryologist to understand the basic scientific background for preimplantation embryo observation and quality assessment. Such knowledge is important in comprehending the correlations between morphological parameters during consecutive observations allowing a more comprehensive interpretation of individual embryo development and its perturbations. The ability to recognize and understand normal and abnormal development will make decision-making easier and the clinical embryologist will be able to give solid informative data to the physician to guide the optimization of treatment. Laboratory management, including quality control and improvement procedures will also benefit from such knowledge.
