Women who underwent surgery in the first trimester were classified as group 1 (n=78) and those in the second trimester were classified as group 2 (n=48). Information on clinical characteristics and pregnancy outcomes was obtained from medical records and follow\u2010up interviews and compared between two groups.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>There were no differences in age, parity, mass size, laparoscopy, and operation time between the two groups. A total of 98 cases were confirmed as ovarian torsion, including 72 cases in group 1 and 26 cases in group 2. Accordingly, adnexectomy was performed more often in group 1 (<jats:italic>P<\/jats:italic>=0.002). No significant differences concerning the rate of abortion, preterm birth, or cesarean delivery were found.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Surgery for adnexal masses performed in the first trimester is almost as safe as that in the second trimester.
