To compare the influence of laparoscopic bilateral tubal ligation, salpingectomy, and proximal cauterization of tubal ligation for treating patients on their ovarian reserve and pregnancy rate after operation. Methods: The clinical data of 142 patients with infertility caused by fallopian tube factors who had accepted the laparoscopic operation from July 2018 to June 2020 were analyzed retrospectively. According to the different treatment methods, these patients were divided into 48 cases with bilateral tubal ligation in group A, 45 cases with salpingectomy in group B, and 49 cases with proximal cauterization of tubal ligation in the group C. The ovarian reserve function and the pregnancy success rate within 1 year after operation of the patients were compared among the three groups. Results: The cross-sectional area of ovary, the antral follicle count (AFC), the end-diastolic flow velocity (EDV), and the peak systolic flow velocity (PSV) of the patients in group A and group B in the 1st, 3rd, and 12th month after operation were significantly higher than those of the patients in group C, and the resistance index (RI) value of the patients in group A and group B was significantly lower than that of the patients in group C (all P<0.05), but which all of the patients had no significant differences between group A and group B (P>0.05). The success rate of pregnancy within 1 year after operation of the patients (52.1%) in group A had no significant difference of that (53.3%) of the patients in group C and that (51.0%) of the patients in group B (P>0.05). Conclusion: Laparoscopic bilateral tubal ligation, salpingectomy, and proximal cauterization of tubal ligation for treating the infertility patients caused by fallopian tube factors have similar success pregnancy rate within 1 year after operation. However, laparoscopic salpingectomy has a greater impact on the ovarian reserve of the patients.
