The uterus is located in the middle of the pelvis, with the bladder in the front and the rectum in the back. The uterus is further divided into anterior, median and posterior positions in the pelvis. The posterior tilted position of the uterus, commonly known as posterior uterus, refers to the tilting of the uterus toward the posterior rectum. If the longitudinal axis of the uterus remains unchanged, the whole uterus tilts toward the posterior, so that the cervix is upturned, i.e., the uterus is posteriorly tilted. The retroversion of the uterus may be due to congenital dysplasia of the uterus, resulting in laxity of the uterine ligaments. It may also be due to repeated abortions and pelvic infections that cause the uterus to tilt backward. Posterior uterine position usually does not require treatment and does not affect pregnancy. If a woman with a retroverted uterus wants to get pregnant, she can put a soft cushion or small pillow of appropriate thickness under her buttocks to raise her hips and allow the semen to concentrate in the posterior vaginal vault. And rest with the hips elevated continuously for about 2 1/2 hours to allow the sperm to enter the uterine cavity more smoothly and increase the chances of conception. If the posterior uterus interferes with the discharge of menstrual blood, causing dysmenorrhea and in severe cases leading to reflux of menstrual blood into the pelvic cavity through the fallopian tubes, it should be treated actively.
