The Uterus Collection consists of Mama-U and Sister-U with accompanying surgical tools. The Uterus Collection helps provide comprehensive IUD training at all stages. Mama-U represents a simplified human anatomical model of a postpartum uterus after birth. It supports training in postpartum intrauterine device insertion, uterine balloon tamponade insertions and other postpartum uterus interventions. Sister-U represents a simplified human anatomical model with both an interval uterus and a post-abortion uterus. It supports training for a variety of sexual and reproductive health interventions such as vaginal examinations, IUD insertion and removal, and for inspecting antevert and retrovert position of the uterus
