Abstract Aim The frequency of postpartum hemorrhage (PPH) is increasing in developed countries, and some reports suggest that assisted reproductive technology (ART) increases various perinatal complications, including PPH. We investigated whether the effect ART pregnancies on incidence PPH modified by mode delivery. Methods A retrospective cohort study was performed. analyzed medical records 2914 pregnant women, 411 achieved ART, which were delivered our hospital from 2017 to 2020. defined as exceeding 90th percentile blood loss per delivery number fetuses. Multivariable logistic regression analysis used assess association between Propensity score‐matched analyses difference Results As previously reported, multivariable showed pregnancy an independent risk factor for with without a 3.39‐fold higher vaginal group ( p < 0.001). Conclusions differed depending Only delivery, increased
