completed the study per protocol. Participants in the active acupuncture group (n 5 9) experienced an average 4.8 (SD 5 2.4) point reduction on a 11 point scale (62%) in pain af-ter 4 weeks, which differed significantly from the control group’s (n 5 5) average reduction of 1.4 (SD 5 2.1) points (P 5 0.004). Reduction in pain in the active group persisted through a 6-month assessment; however, after 4 weeks, dif-ferences between the active and control group decreased and were not statistically significant. All HRQOL measures indicated greater improvements in the active acupuncture group compared to the control; however, the majority of these trends were not statistically significant. No serious adverse events were reported. Chronic pelvic pain in adolescent girls is the cause of nearly 10 % of their outpatient gynecology visits.1 It is believed that 25e38 % of adolescents with chronic pelvic pain (i.e. 3 to 6 months of pain) have endome-triosis.2 In addition to an increased risk of infertility associated with endometriosis, endometriosis-related chronic pelvic pain in adolescent girls is associated with significant functional morbidity including anxi-ety, depression, absence from school, and decreases in psychosocial functioning.3,4 Although much research has focused on treatments for women with pelvic pain between the reproductive ages of 25 and 40,5 far less attention has been paid to adolescents with this disease. Consequently, treatment options for adolescents are more limited than for adults. Current recommendations as outlined by the
