Prolapsed double uterus in pregnant woman.
A double uterus is known as uterus didelphys. Though the condition doesn’t tend to interfere with pregnancy (when conception occurs - it’s not uncommon for those with a double uterus to have trouble conceiving), it frequently occurs along with other gynecological problems, such as weak uterine ligaments. Since surgical intervention was still fairly risky, even after the advent of aseptic procedures, gynecological surgery was not commonly used for conditions such as prolapsed uterus.
