The principle of the belt ring

When it comes to the term "IUD", I believe many women of childbearing age will not feel unfamiliar with it. Because the IUD is commonly known as placing an IUD into the uterus of women of childbearing age, it can greatly play a contraceptive role without suppressing ovulation. The IUD is relatively safe, simple, and reversible contraceptive method. So what is the principle of the belt ring?

At present, most women of childbearing age in my country choose this method of wearing an IUD to avoid pregnancy. In addition to the fact that other contraceptive methods are not good, they may also cause adverse reactions and even affect women's endocrine system. Now let me introduce to you the principle of the belt ring.

The scientific name of the "ring" is intrauterine device, which is placed in the uterine cavity of women of childbearing age to achieve the purpose of contraception through mechanical stimulation and interference of chemical substances. It does not inhibit ovulation and does not affect the female endocrine system, thus avoiding the adverse reactions of general drug contraceptives. After years of practical improvement, most of the IUDs currently used in clinical practice are copper-containing or drug-containing IUDs. The stent materials are plastic, polyethylene, memory alloy, etc., and the shapes are not single, including round, T-shaped, V-shaped, Y-shaped and chain-shaped. IUDs made of different materials and in different shapes have their own characteristics, and therefore can be suitable for women with different physiques and needs.

The IUD is a safe, simple and effective contraceptive device. It will not affect endocrine system and will not bring harm to sexual life.

effect

1. Mechanical action: As a foreign body, it causes a mild, chronic, non-bacterial inflammatory reaction in the endometrium, thereby changing the intrauterine environment and preventing the fertilized egg from implanting.

2. Effect of inflammatory cells: When the degenerative substances of inflammatory cells reach a certain concentration, they poison the embryo and prevent it from continuing to develop.

3. Effect of prostaglandins: Intrauterine contraceptive device can stimulate the endometrium to produce prostaglandins, which cause the uterus and fallopian tube to contract and abnormal peristalsis, while enhancing the effect of estrogen, making the environment in the uterine cavity unfavorable for implantation.

4. Action of active substances: The intrauterine contraceptive device can be made of metallic copper. It can achieve the purpose of contraception through local changes in the internal environment such as the endometrium and uterine fluid and its toxic effect on sperm.

5. Phagocytic function: mainly macrophages and neutrophils play the role of phagocytosis and destruction of sperm.

Everyone already knows the principle of the belt ring. In fact, compared with other contraceptive methods, the IUD is a relatively safe, simple and effective contraceptive device. Not only does it not cause harm to women's bodies, it also does not produce various adverse reactions. Therefore, wearing an IUD has always been the choice of many women.
