Several studies have examined the efficacy of interventions to reduce pain for interval IUD insertion for nulliparous and multiparous women (Hubacher, Reyes et al. 2006; Edelman, Schaefer et al. 2011; Maguire, Davis et al. 2012; Swenson, Turok et al. 2012). Procedural aspects and clinical circumstances of postplacental IUD insertion differ substantially from those associated with interval insertion, preventing extrapolation of findings from studies of interval IUD insertion to postplacental insertion.
