What is embryo grading? Day 3, Day 5, Success Rates
2023年4月10日 · Through microscopic examination, embryos are categorized as ‘good’, ‘average’ or ‘poor’ quality based on certain criteria such as cell size, shape and number of cells. On Day 3, an embryo is referred to as a Day 3 Embryo or an 8-cell cleaving embryo. By Day 5, it’s known as a Blastocyst or a Day 5 Embryo.
