Pre- and post-treatment disease stages, based on ASRM endometriosis scores, for individual patients (n = 10). (A) Baseline: first-look laparoscopy 1 month before treatment; (B) one-month post-treatment: second-look laparoscopy 1 month after treatment. Determinations for each patient before and after treatment are interconnected.

Pre- and post-treatment DEXA scan results for bone density in the hip and spine of individual patients (n = 10). (A) hip; (B) spine. Determinations for each patient (numbered) before and after treatment are interconnected. A slight but statistically significant improvement in hip bone density (P = .04) was noted. No statistically significant difference was detected between groups with respect to spine bone density.
