Embryo Grading: What Do the Grades Mean for Your IVF Success?

Following an egg retrieval and fertilization in the IVF process, the embryology team monitors the developing embryos daily. By day 5 or 6, a healthy embryo reaches the blastocyst stage. Before transfer, embryologists assign a score to each blastocyst to evaluate its viability. If you are reviewing your laboratory report, understanding the role of embryo grading is key to managing your IVF expectations.

This comprehensive guide explains the Gardner grading system, clarifies the numbers and letters used, and details the success rates associated with different embryo grades.

Grades and Selection

Gardner grades evaluate blastocyst expansion, inner cell mass, and trophectoderm. AA or BB grades have high success rates, while CC has lower rates. Read about transfer preparation in our endometrial scratching guide. Select healthy blastocysts to support transfer success (read details in our successful implantation guide).
