A retroverted uterus (tilted uterus, tipped uterus) is a uterus that is tilted backwards instead of forwards. This is in contrast to the slightly "anteverted" uterus that most women have, which is tipped forward toward the bladder, with the anterior end slightly concave.
Between 1 in 3 and 1 in 5 women (depending on the source) has a retroverted uterus, which is tipped backwards towards the spine.
