Yes. There are three grading systems commonly in use. According to the American Society of Reproductive Medicine guidelines, an individual’s endometriosis can be classified as stages I–IV, as follows: Stage I is minimal, Stage II is mild, Stage III is moderate, Stage IV is severe.[1] Endometriosis can also be graded by the Endometriosis Fertility Index (EFI), which grades endometriosis according to its impact on fertility,[2] or the Enzian classification system, which is designed to describe both the location and severity of endometriosis.[3] The most commonly used system is the American Society of Reproductive Medicine’s, but deeply infiltrating endometriosis (DIE) is better described by the Enzian system, and the EFI is much more useful for predicting endometriosis’s impact on fertility.
