Endometriosis and spontaneous hemoperitoneum in pregnancy: evaluation of the magnitude of the risk in women becoming pregnant via in vitro fertilization

ObjectiveTo estimate the frequency of spontaneous hemoperitoneum in pregnancy (SHiP) women with endometriosis achieving vitro fertilization (IVF).DesignRetrospective case series.SettingReferral academic assisted reproductive technology (ART) center.Patient(s)Three hundred and forty-eight a history surgery for ovarian endometriomas or deep endometriotic nodules detected at basal transvaginal ultrasound performed before IVF cycle.Intervention(s)Information obtained from patients’ charts on characteristics, cycle, outcomes, binomial distribution model created to determine 95% confidence interval (CI) proportion SHiP.Main Outcome Measure(s)Rate SHiP.Result(s)Overall, 362 pregnancies were included, among which 238 (66%) had previous 231 (64%) (107 women, 30%, both). Pregnancies achieved after fresh frozen cycles 244 (67%) 118 (33%) respectively. One SHiP was recorded, corresponding rate 0.3%.Conclusion(s)In general population undergoing IVF, is uncommon. Future studies should better identify risk factors disentangle subgroups higher risk. To (IVF). Retrospective series. Referral center. Three cycle. Information SHiP. Rate Overall, 0.3%. In
