Effect of salpingectomy on ovarian reserve: A systematic review and meta‐analysis

Abstract Aim To determine the effect of salpingectomy on ovarian reserve. Methods PubMed, EMBASE, Web of Science, Dynamed plus, and Cochrane Controlled Trials Register databases were searched from their inception to December 2020 to identify relevant studies, including cross‐sectional studies, retrospective studies, and randomized controlled trials. Studies that compared anti‐Müllerian hormone (AMH) levels and/or antral follicle count (AFC) between the control and salpingectomy groups or before and after surgery were included. Results Twenty‐one articles were included in the systematic review. Meta‐analyses were performed on 16 studies in which data were presented as mean ± SD values. A meta‐analysis comparing AMH levels before and after surgery in the same patients showed no significant decrease in all cases, irrespective of whether it was unilateral or bilateral salpingectomy. There was no significant decrease in the AFC in the meta‐analysis comparing levels before and after bilateral salpingectomy, either. In contrast, in the case–controlled study the salpingectomy group had significantly lower levels of AMH in all meta‐analyses of unilateral and bilateral surgery (mean difference: −0.31, 95% confidence interval [CI]: −0.55, −0.07), only unilateral cases (mean difference: −0.28, 95% CI: −0.50, −0.06), and only bilateral cases (mean difference: −0.71, 95% CI: −1.19, −0.23). The salpingectomy group that included unilateral and bilateral cases had significantly lower AFC compared with no‐surgery controls (mean difference: −1.31, 95% CI: −2.13, −0.48). Conclusion Although not conclusive, it does appear that patients who underwent salpingectomy (either unilateral or bilateral) have a decreased ovarian reserve.
