A new classification system of endometriosis proposed by the American Fertility Society (AFS classification) was utilized to categorize patients with endometriosis after surgical treatment and the following results were obtained. 1. AFS classification system was useful to categorize patients with endometriosis, because of a simple and objective point system. 2. There were discrepancies in categorized patients between AFS system and a system proposed by Acosta et al. (Acosta's system). One-third of patients categorized as "Severe" by Acosta's system was classified to be "Moderate" by AFS system. These discrepancies occurred when lesion of endometriosis was just restricted within ovaries. 3. Conception was reduced once ovaries were involved and fecundability rate was significantly reduced if ovarian endometrioma was greater than 3cm in diameter. 4. Acosta's system revealed differences among fecundability rate among the different categories, however, AFS system could not demonstrate a direct correlation between the categories of endometriosis and fecundability rate.
采用美国生育协会提出的一种新的子宫内膜异位症分类系统（AFS分类）对手术治疗后的子宫内膜异位症患者进行分类，得出以下结果。1. AFS分类系统有助于对子宫内膜异位症患者进行分类，因为它有一个简单且客观的评分系统。2. AFS系统与阿科斯塔等人提出的系统（阿科斯塔系统）在分类患者方面存在差异。阿科斯塔系统分类为“重度”的患者中有三分之一被AFS系统分类为“中度”。当子宫内膜异位症病变仅局限于卵巢时，就会出现这些差异。3. 一旦卵巢受累，受孕率就会降低，如果卵巢子宫内膜瘤直径大于3厘米，受孕率会显著降低。4. 阿科斯塔系统揭示了不同类别之间受孕率的差异，然而，AFS系统未能证明子宫内膜异位症类别与受孕率之间存在直接关联。
