Causes of Retroverted Uterus
Retroverted uterus is relatively common in clinical practice. In this condition, the longitudinal axis of the uterus remains unchanged, but the entire uterus tilts backward—resulting in a retroflexed position—causing the cervix to tilt posteriorly (i.e., uterine retroversion). This orientation may prevent the cervix from being adequately immersed in the seminal pool, potentially impairing conception. The main contributing factors to a retroverted uterus include the following:

1. Inflammation: Gynecological infections—involving the uterus or ovaries—may lead to adhesions between the uterus and rectum, pulling the uterus backward.
2. Congenital uterine hypoplasia: Some women are born with underdeveloped uteri, resulting in relatively lax uterine ligaments and increased susceptibility to uterine displacement in any direction.

3. Sleeping posture: Prolonged supine sleeping may gradually cause uterine retroversion due to gravitational effects. Adjusting sleep posture often allows for gradual correction.
4. Effects of induced abortion: Induced abortion imposes significant physical stress on women. Repeated abortions or inadequate post-abortion care may contribute to uterine retroversion.
