To compare fertility and reproductive outcome after surgical, medical, and expectant management for tubal ectopic pregnancy (EP). 133 of 228 patients, who were managed between January 2012 and December 2017 for a tubal EP, tried to conceive immediately after treatment: 86 out of 173 (49.7%) underwent surgical treatment; 38 (21.9%) were treated with methotrexate (MTX), and 49 (28.3%) had expectant management. Clinical data were retrieved by medical records, fertility outcomes were obtained by phone follow-up. The cumulative incidence (CI) of intrauterine clinical pregnancy (CP), miscarriage, live birth (LB), and recurrent EP, and the time between treatment and first intrauterine CP were compared between women treated with MTX, surgery and expectant management. The CI of intrauterine CP starting from 12 months after the EP was 65.3% for the expectant management, 55.3% for the MTX group, and 39.5% for surgery (p = 0.012). Post-hoc analysis showed expectant management having higher intrauterine CP and LB, and shorter time between treatment and first intrauterine CP compared to surgery (p < 0.05). The CI of recurrent EP was comparable between the 3 groups. The analysis stratified per βhCG cut-off of 1745 mUI/mL and EP mass cut-off of 25 mm reported consistent results. Women successfully managed by expectation appear to have better reproductive outcomes compared to women who underwent surgery, with the shortest time to achieve a subsequent intrauterine CP. Therefore, if safely applicable the expectant management should be considered in the case of tubal EP. The fact that the chosen treatment was primarily guided by the βhCG value and EP mass diameter based on the protocol, which is intrinsically related to the characteristics of the EP, represents the main limitation of the present study. Indeed, we cannot completely exclude that the observed differences between treatments are related to the EP itself instead of the treatment.
