In women with bilateral obstruction (14 studies, 617 patients), the clinical pregnancy rate was 27% (95% CI 23–32%). Our meta-analysis demonstrated that the pooled cumulative clinical pregnancy rates were 22.3% (95% CI 17.8–27.8%) at 6 months, 25.8% (95% CI 21.1–31.5%) at 9 months, 26.4% (95% CI 23.0–30.2%) at 12 months, 26.0% (95% CI 22.8–29.7%) at 18 months, 27.0% (95% CI 24.0–30.5%) at 24 months, 27.9% (95% CI 24.9–31.3%) at 36 months and 28.5% (95% CI 25.5–31.8%) at 48 months. The pooled live birth rate (14 studies, 551 patients) was 22% (95% CI 18–26%). The pooled ectopic pregnancy rate (27 studies, 1556 patients) was 4% (95% CI 3–5%).
