A uterus that lies more towards the back than the front. Retroversion of the uterus may be normal and, of itself, this is not a cause of infertility; rarely it can repeatedly get in the way during sex and cause pain, in which case there are operations available to bring it forward, out of the way. Retroversion can also develop from scarring caused by endometriosis, in which case there can be pain with sex (dyspareunia) and infertility (caused by the endometriosis).

Refers to the position of the uterus when it is tilted backward in relation to the direction of the vagina. A retroverted uterus is not always abnormal. Sometimes, however, a uterus can be pulled into a retroverted position by endometriosis affecting the uterosacral ligaments. A sharply retroverted uterus can cause pain during and after sex (dyspareunia). Opposite to anteverted.
