In total, 147 patients with dysmenorrhea who underwent conservative laparoscopic surgery for DIE were enrolled. Following surgery, patients received either postoperative adjuvant therapy (GnRHa or OCs) for 6 months or expectant treatment according to a shared medical decision-making approach. The primary outcome was the postoperative recurrence of dysmenorrhea. The secondary outcomes included reproductive outcomes and drug-induced side effects.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The generalized estimating equation analysis illustrated that the visual analog scale for dysmenorrhea was significantly higher in the adjuvant treatment group than in the expectant treatment group. Kaplan\u2013Meier analysis and the log-rank test demonstrated that the cumulative recurrence rate was higher in the expectant treatment group than in the adjuvant treatment group, but no difference was noted between the two hormonal treatments. Similar cumulative 24-month clinical pregnancy rates were observed among the three groups.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
