[Studies on the classification of endometriosis].
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.
