Does the uterus move?

The uterus can tilt forward or backward to a certain extent. A small degree of tilt will not have a big impact on the health of the uterus, but if it happens too much, it will definitely have an impact on the health of the uterus. The uterus will move to a certain extent, but you need to be careful because excessive movement will affect the health of the uterus.

1. What is uterine displacement?

Excessive antevertion or retroversion of the uterus. The normal position of the uterus is anteverted, that is, the fundus of the uterus is toward the pubic bone, and an obtuse angle of 120° to 150° is formed between the cervix and the uterine body. About 80% of women have an anteverted uterus, 20% have a retroverted uterus, and less than 5% have symptoms. Retroversion and flexion of the uterus is the most common displacement, followed by antevertion and antevertion. Most people have no symptoms, but a few with retroflexion may experience back pain, anal distension, dysmenorrhea, excessive vaginal discharge, and in severe cases, infertility. Gynecological examination can confirm the diagnosis. Asymptomatic people do not need treatment and can naturally return to normal position by lying on their knees and chest every day. For those with symptoms, manual reduction can be performed and a pessary can be inserted to maintain the anteversion of the uterus. If combined with other diseases, treatment should be directed at the cause.

2. Common types of uterine displacement

1. Retroverted uterus

The most common. If the entire uterus moves toward the sacral concavity while the relationship between the uterine body and the cervix remains unchanged, it is called retroversion of the uterus; the uterine body may also be significantly retroflexed. The retroverted uterus can be divided into three degrees according to the degree of retroversion: the uterine fundus is inclined towards the sacral promontory (degree one), the uterine fundus is inclined towards the sacral concavity (degree two), and the uterine fundus is inverted into the rectouterine pouch (degree three) (Figure 2). A mildly retroverted uterus that is mobile is usually asymptomatic. Those with obvious posterior position are often accompanied by ovarian prolapse, and may experience soreness in the waist and back, a feeling of heaviness in the anus, or pain during sexual intercourse. A retroverted and retroflexed uterus can cause abnormal menstruation, dysmenorrhea, and excessive leucorrhea due to thickening of the uterine wall, or it can cause infertility by hindering the entry of sperm into the uterine cavity due to the upward external os of the cervix.

2. Excessive anterior position of the uterus

Most of them are congenital lesions. The uterine body is small and the cervix is ​​slender. The angle formed by the uterine body and cervix is ​​less than 90°, and the external cervical opening faces the anterior wall of the vagina. It generally does not affect health, but may cause dysmenorrhea or infertility. Treatment can be with cervical dilation to widen the cervical canal and/or artificial cyclical therapy with sex hormones.
