The principle of contraceptive ring
Release time : 09/19/2025 09:30:04
The contraceptive ring, also known as the IUD (Implantable Birth Control Device), works by continuously scraping the lining of a woman's uterus, causing sterile inflammation. This condition prevents embryos from implanting normally within the uterus and thus prevents conception, leading to miscarriage and achieving contraception.
Additionally, there are roles of phagocytic cells, inflammatory cells, prostaglandins, and active substances.
The principle of contraception is that it continuously scratches the uterine wall of women, causing sterilization inflammation in the uterus, so that embryos cannot normally implant in the uterus and cannot conceive, thus achieving the purpose of contraception.
The contraceptive ring is essentially a long-term, gentle form of "Palace abortion". Many Chinese women choose this method for contraception.
This is the basic mechanical effect of the contraceptive ring.
Additionally, there are roles of phagocytic cells, inflammatory cells, prostaglandins, and other active substances.
The role of phagocytes is mainly in the engulfment and destruction of sperm by macrophages and neutrophils.
The role of inflammatory cells refers to the event where the concentration of degenerative substances in inflammatory cells reaches a certain level that the embryo cannot continue its development.
The function of the prostate is to stimulate the uterine endometrium by means of a contraceptive ring, producing prostaglandins that cause abnormal contractions and movements of the uterus and fallopian tubes. At the same time, it enhances the effects of estrogen, making the uterine environment unfavorable for implantation.
The active substance acts by local changes of the intrauterine environment, including the endometrium and uterine fluid, as well as its toxic effects on sperm.
Is the contraceptive ring effective? The contraceptive ring can effectively prevent pregnancy for a long time and is safe without significant side effects. But is it really good to use the contraceptive ring? Is it guaranteed that it will not result in pregnancy? Circumcision is a highly invasive surgical procedure on women, which may damage the basal layer of the endometrium, making it difficult for the endometrium to regenerate.
The contraceptive method of putting in an intrauterine device is relatively long-term and effective. Another advantage is that it eliminates the need to undergo repeated hospital abortion procedures.
The upper layer of the uterine lining is where monthly menstrual bleeding occurs, and then this lining's basal cells divide and grow to form the uterine lining.
However, the harm caused by the intrauterine device to women is not negligible.
During menstruation, the upper layer of the endometrium sheds. The contraceptive ring directly mechanically scrapes or copper ions produce cytotoxic effects on cells, damaging the basal layer of the endometrial stroma, thereby leading to fibrotic changes in the endometrium.
Moreover, women who undergo intrauterine device insertion generally experience numerous adverse reactions, including lower back and lumbar pain, light bleeding during menstruation, prolonged periods, and increased vaginal discharge. These symptoms require time to adapt to.
Types and Prices of Contraceptive Rings: The following are the main types of contraceptive rings: 1. Copper Intrauterine Device: This type is an active intrauterine device, which is widely used. It enhances the effectiveness of contraception by killing sperm or fertilized eggs through copper.
2. Inert intrauterine device: It is mainly made of stainless steel wire, plastic or silicone, such as metal single ring, Fried Dough Twists ring and stainless steel uterine ring.
3. Released progesterone intrauterine device: This contraceptive ring releases progesterone slowly and consistently into the uterine cavity, which can reduce bleeding.
4. Release the intrauterine contraceptive device containing an anticoagulant.
The foreign body effect of the contraceptive ring can cause endometrial inflammation without sex, which affects the implantation of fertilized eggs.
The intrauterine device containing progesterone can release progesterone continuously and in a small amount into the uterus, causing endometrial atrophy, which is not conducive to the implantation of fertilized eggs.
Different contraceptive rings cost different amounts.
The cost of a regular IUD is generally quite affordable, around 100 yuan.
If you choose to use an imported contraceptive ring, there is a possibility that the cost of both the ring and the procedure will increase, ranging from several hundred to a thousand.
Precautions for Using the IUD: After insertion, women must ensure adequate rest and refrain from engaging in strenuous physical activities.
Rest at least one or two days to avoid the ring slipping off and bleeding.
If there are symptoms of bleeding, such as excessive vaginal bleeding exceeding menstrual flow and lasting for an extended period, it is imperative to seek medical examination immediately.
Pay special attention in the first three months, to see if the ring has come off.
Generally, it is necessary to undergo regular examinations after the placement of an intrauterine device (IUD). The first examination should be conducted 3-6 months after the placement, followed by a checkup at 12 months and then annually thereafter.
Hormonal IUDs can cause certain adverse reactions, including lower back pain and abdominal discomfort. If these are severe, it is not normal and should be checked at a hospital.
Personal hygiene is crucial after getting an IUD. It is important to clean the vulva regularly and avoid sitting in a basin or bathing for 2 weeks, as well as sexual intercourse for 3 weeks to prevent infection.
Finally, it's important to ensure adequate nutrition.
Consume more foods rich in iron, including lean meat, liver, kidney, and soy products. Additionally, vegetables and fruits should be consumed in abundance.
The side effects of contraceptive rings Although contraceptive rings are relatively safe and effective in the long term, they also have certain side effects and adverse reactions
The most common symptoms are back pain and soreness, with a minority of women experiencing lower abdominal pain.
If you are using a contraceptive ring with tailing, it may lead to an increase in vaginal discharge, specifically a notable increase in the amount of cervical secretions.
After some time, there might be symptoms such as fever in the whole body and lower abdominal pain. If these symptoms occur, it is important to seek medical attention promptly.
Bleeding after the insertion of an IUD is a relatively common side effect.
Bleeding generally occurs within 3 to 4 days after the insertion of an intrauterine device (IUD), and most women experience this phenomenon. The duration of bleeding is usually within a week.
Bleeding is caused by the uterine injury due to the intrauterine device, generally no treatment needed for recovery.
However, if there is prolonged bleeding, it is also necessary to seek timely medical attention at a hospital.
Excessive menstrual flow is a symptom of the initial bleeding from the IUD and can lead to an extension of the menstrual period for women.
This is also due to damage to the endometrial lining.
There is a possibility of uterine perforation, damage to other organs, and the occurrence of fibrosis due to an ectopic pregnancy.
If you have an intrauterine device (IUD) and engage in sexual activity too early, you may still experience infections.
Therefore, after the insertion of the intrauterine device, women should pay attention to personal hygiene.
