The incidence of uterine perforations in this study was low, although higher than the commonly reported rate. Approximately one third of perforations are detected 12 months after insertion. Clinical sequalae of perforations are generally mild and associated with a very low risk of injury to intra-abdominal and pelvic structures. Implications Uterine perforation is a rare risk associated with intra-uterine device use. Late diagnosed perforations can occur, although women can be reassured that the morbidity associated with detection and removal is low.
DNG/EV is associated with similar contraceptive effectiveness in typical-use settings when compared to oCOC and LNG. There was no difference observed between cohorts in fertility following OC use.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
