Some female friends want to use an IUD as a contraceptive measure, but they are not clear about the types of IUDs available. A doctor from Hefei Changzheng Hospital said that women who choose to use an IUD as a contraceptive measure must choose a suitable one, otherwise some side effects may occur. Inert IUDs are made of inert raw materials, such as stainless steel, plastic polyester and silicone. Its physical and chemical properties are stable, and the IUD itself does not release any active substances, such as metal single ring, peach ring, mixed ring, contraceptive surgical flower, uterine ring, Ota ring, ring-shaped IUD, etc.

Because the contraceptive effect of inert contraceptive rings is relatively weak, this type of contraceptive ring method has been gradually replaced in countries around the world and replaced by specific contraceptive rings.

Specific IUD: refers to a new generation of IUD that uses an IUD as a medium, contains metal materials such as copper or zinc, estrogen, hemostatic drugs and permanent magnetic materials. After being inserted into the uterine cavity, the body can slowly release active substances. This type of IUD insertion method can improve the actual effect of contraception and reduce side effects.

You should know that there are many types of IUDs. Contraceptive rings are generally made of corrosion-resistant plastic or metal materials, and some are added with some drugs (such as releasing hormones or anti-inflammatory drugs). The uterine ring has various shapes such as round, intrauterine, T-shaped, etc. Doctors can choose the appropriate uterine ring according to the condition of each person's uterus. The IUD is a special female contraceptive device placed in the uterus. The contraceptive ring that everyone is familiar with is a type of IUD.

Frequently asked questions

1. Uterine perforation

The mechanism of uterine perforation caused by IUD insertion is not well established. It is generally believed that it may be caused by the inappropriate size of the uterus or the doctor's poor operation. In addition, when women exercise excessively, the contraceptive ring in the body may also cause damage to the uterus due to physical inertia. Uterine contractions of unknown cause may also squeeze the contraceptive ring and cause uterine perforation.

2. Damage to other internal organs

In rare cases, the IUD can cause perforation of the uterus and enter the abdomen, causing dislocation of the IUD. The IUD may be lodged in the bladder, pelvis, or mesentery.

3. Excessive menstrual flow

Some contraceptive rings contain iodine ions, which have cytotoxic and hemolytic effects, resulting in excessive menstrual flow, which is normal.

4. Soreness

Some women will experience soreness and discomfort in the lower abdomen or lower back after the ring is placed. This is because the contraceptive ring placed in the uterus is a "foreign body" to the uterus, especially when it is slightly larger or located lower. The uterus contracts to expel this "foreign body", causing uterine contraction pain.

5. Uterine wall fibrosis

The IUD is essentially a foreign body in the human body. It is common knowledge in medicine that foreign bodies in the human body can cause mechanical damage and inflammation of some tissues, as well as fibrosis. Ten to twelve years after the IUD was inserted, fibrosis may occur in the uterine wall.
