Choi HG, et al. - Researchers examined how hysterectomy with/without bilateral oophorectomy influences the occurrence of osteoporosis via using a national sample cohort from South Korea. Data for patients who had undergone hysterectomy (n=9,082) and for a 1:4 matched control group (n=36,328) were extracted using the national cohort study from the Korean National Health Insurance Service. In all, the occurrence of osteoporosis was increased in patients who had undergone hysterectomy vs that in matched control participants, irrespective of bilateral oophorectomy status.
