What should I do if the upper ring is displaced?

For women, IUD insertion is a common contraceptive method that can achieve long-term contraceptive effects. However, some women are prone to displacement after IUD insertion, so you must pay attention to understand the causes, and if you want to get an IUD inserted, you must go to a regular hospital.

1. The shape of the uterus is an inverted pear and the uterine cavity is an inverted triangle, but this shape will change due to uterine movement. The myometrium undergoes periodic segmental contractions. During menstruation, the upper part of the uterine fundus contracts and the lower part relaxes, causing the triangle within the uterine cavity to become smaller. The opposite happens during the period between two menstrual periods (ovulation period), causing the uterine cavity to become larger.

2. In view of the above reasons, when selecting materials for the manufacture of intrauterine contraceptive devices, materials with good elasticity are generally selected as stents, and various contraceptive rings suitable for the uterine cavity are made according to the morphological characteristics of the uterine cavity. Because the contraceptive ring can adapt to the shape of the uterine cavity and has a certain degree of elasticity, it can better adapt to changes in the shape of the uterine cavity and uterine movements. Uterine movement is also more obvious during sexual intercourse.

3. The reason for ring displacement is mostly due to improper selection of ring size. Intrauterine displacement is often caused by a small ring size and a large uterine cavity. Movement of the uterine muscle layer can cause the ring to move downward. In most cases of ring displacement, the ring size is too large. When the myometrium moves, the ring can damage the endometrium and myometrium, and perforation may occur over time.

4. In summary, as long as the size and shape of the ring are appropriately chosen, the movement of the uterine muscle layer, including the rhythmic contraction of the uterus caused by sexual intercourse, will not cause the ring to shift. Only in a few patients with inappropriate ring number selection will the ring position be affected, and attention should be paid.
