Endometriosis fertility index score maybe more accurate for predicting the outcomes of in vitro fertilisation than r-AFS classification in women with endometriosis

Reproductive biology and endocrinology : RB&E ·doi:10.1186/1477-7827-11-112

BACKGROUND: Endometriosis is a common disease. The most widely used staging system of endometriosis is the revised American Fertility Society classification (r-AFS classification) which has limited predictive ability for pregnancy after sur…
