Intrauterine device insertion is the clinical procedure involving the placement of an intrauterine device (IUD) into the uterine cavity for contraception or other therapeutic purposes. As an academic concept and research area, it encompasses the systematic investigation of the techniques, outcomes, associated factors, and implementation of this procedure within healthcare settings. Research in this domain explores optimal methodologies, pain management, provider training, patient experience, and the impact of insertion services on reproductive health access and public health outcomes globally, highlighting its significance in expanding access to highly effective long-acting reversible contraception.
