Why do most women not want contraception?

Intrauterine devices, because some types are annular in shape, were basically referred to as [IUD] [contraceptive ring] before.

In China, due to the family planning policy, the usage rate among married and childbearing women is very high, and 80% of IUD users in the world are in China.

However, the reputation of IUD in China does not seem to be very good.

For example, it is said that after the ring is put on, there will be stomachache, irregular menstruation, pelvic inflammatory disease and even ectopic pregnancy.

Some women feel uncomfortable just seeing this title, [let women ring, why not let men ligate? ].

In fact, just like other conventional contraceptive methods, IUD also has corresponding advantages and disadvantages. Although IUD also has surgical risks and complications, it is still a safe and effective contraceptive method in general. Below, Dr. Clove will talk about the problem of IUD.

This is not a call or recommendation for everyone to use IUD, but an introduction to a medically recognized and effective conventional contraceptive method, which can be decided after consulting a doctor according to personal choice.

Mechanism of IUD

The mechanism of IUD is mainly to stimulate inflammatory reaction in uterine cavity and interfere with fertilization and implantation.

Don’t be afraid when you see the inflammatory reaction. The inflammatory reaction here is different from the usual bacterial infection. This is a local aseptic inflammatory reaction. The relationship between IUD and pelvic infection will be explained in detail later.

Advantages of IUD

  1. The effect is exact: the contraceptive success rate is high;

  2. Simple and long-term effect: After one placement, according to different ring models, it can generally be guaranteed to be effective for 5-15 years, during which time contraception does not need to be considered.

  3. Good reversibility: fertility can be restored quickly after taking the ring;

  4. Cheap price: Because of the family planning policy, many types of intrauterine rings in China are free of charge, as long as they pay very little surgical expenses, which is much cheaper than other contraceptive methods.

Possible problems

What are the possible unfavorable factors for using IUD for contraception?

  1. Abnormal menstruation: For example, increased menstrual volume, prolonged menstrual period or sustained small amount of vaginal bleeding are the main reasons why many women require ring removal.

  2. Abdominal pain: There are very few people who may not adapt to the IUD and will suffer from lower abdominal pain, waist soreness or sexual intercourse pain after placement. However, with the development of IUD materials, this situation is less and less, and usually it can be relieved after taking the ring.

  3. Unexpected pregnancy: Because there is no method that can achieve 100% successful contraception, there is a situation of [ring pregnancy]. The contraceptive effect of IUD is still reliable, and the failure rate of long-term use is similar to tubal ligation. Of course, if contraception fails and [ring pregnancy] occurs, then it may be intrauterine pregnancy or ectopic pregnancy.

Taboos in the Use of IUD

Women under the following circumstances are not suitable to use IUD:

    A pregnant woman; Recently, overdue abortion has just occurred. The uterine cavity structure is distorted and deformed. Hemorrhage of unknown cause exists; Patients with gestational trophoblastic tumor, cervical cancer and endometrial cancer; Acute pelvic inflammatory disease or attack of pelvic inflammatory disease within 3 months; Sexually transmitted diseases are onset or within 3 months; Pelvic tuberculosis; I or my sexual partner have multiple sexual partners.

Some statements about IUD

1. Extrauterine pregnancy

The statement that IUD causes ectopic pregnancy is widely circulated among the people, which needs a little explanation here.

If the use of IUD contraception fails, the proportion of ectopic pregnancy is higher than that of non-contraception. In fact, if other contraceptive methods fail, the proportion of ectopic pregnancy is higher than that of non-contraceptive methods, such as tubal ligation.

However, because the failure rate of IUD contraception is very low (0.1% ~ 0.8%), if all women who use IUD are examined, the probability of ectopic pregnancy is still very low, which is lower than that of women who do not use contraception.

In other words, IUD contraception not only reduces the incidence of intrauterine pregnancy, but also reduces the incidence of ectopic pregnancy. Because it does not increase the incidence of ectopic pregnancy, it cannot be said that IUD will lead to ectopic pregnancy.

2. Pelvic infection

Although it was believed in the 1970s and 1980s that IUD would increase the risk of pelvic infection, subsequent studies found that the selection of the test control group at that time was unreasonable and lacked control of infection factors, thus exaggerating the relationship between IUD and pelvic infection.

At present, Pelvic infection associated with IUD, It is mainly related to sexually transmitted infections. Even if IUDs increase the risk of pelvic infection in people with low risk of sexually transmitted diseases, this is only caused by the operation itself. A large international cohort study shows that the incidence rate of acute pelvic inflammatory disease in women using IUDs is about 0.6 per 1,000 women per year.

Placement of the ring

If you want to use the IUD, you need to perform a minor operation. The doctor places the IUD into the uterine cavity through the vagina, which is called “putting the ring”.

Placement of the ring itself is an unfavorable factor, because all operations are risky, and possible complications include intraoperative hemorrhage, uterine perforation and postoperative infection.

Although these complications sound terrible, but the actual incidence rate is very low. For example, the amount of bleeding in ring surgery is usually 5 ~ 10 mL, which is far less than the amount of bleeding in a menstruation, so there is no need to worry too much.

The risk of infection caused by ring surgery is about 1/1000 women per year. The risk of uterine perforation is also about 1/1,000 women. Moreover, even women who have not yet given birth or have had a history of pelvic inflammatory disease can also use birth control and even women who have not yet given birth or have had a history of pelvic inflammatory disease can also use IUD. However, during acute inflammation, IUD placement cannot be performed.

Although the risk and pain of surgery are very small, it is indeed a relatively difficult obstacle for those who are afraid of surgery. Once successfully placed, it can eliminate the need to worry about contraception for a long time.

Surgical removal of ring

Each IUD has its corresponding life span, such as five years, ten years or even fifteen years. Usually the IUD exceeds its service life. Whether considering the contraceptive effect or the occurrence of long-term complications, it is recommended to remove it in time.

Just like putting the ring, taking the ring also requires an operation, and it is also more convenient to operate, with less risk and pain.

In the past, some IUDs were made into rings, which required doctors to hook to the IUD with a small hook and then pull out the uterine cavity. Occasionally, it may not be so easy to take out because the hook cannot be reached. Now most IUDs will have tail filaments, which are easy to take out in some shapes and convenient for operation.

But clinical often encounter postmenopausal women, because afraid of surgery and has been dragging not to take the ring. They may not have realized the harm of continuing to use intrauterine devices before, and there is no special discomfort in life at ordinary times. Therefore, even if the ring operation is simple and easy to implement, after all, it is still an operation, or nervous and afraid of taking the ring.

Why do you have to take it out?

In fact, compared with women of childbearing age, it is much more necessary to take the ring for postmenopausal women.

1. No need for contraception

Postmenopausal women no longer need contraception. Since they are menopausal, it is impossible to get pregnant again. Naturally, there is no need for contraception, so there is no need to keep the IUD in the uterus.

2. Possible risks

Because after menopause, the level of estrogen and progesterone in the body of a woman decreases significantly, resulting in uterine atrophy, which means that the uterus will become smaller than before.

However, the IUD in the uterus will not change, and the reduced uterus may be embedded into the uterine wall by the IUD, which is clinically called IUD incarceration and may cause discomfort such as abdominal pain and infection.

I’m afraid it’s not as simple as what I said before to take the ring again at this time. Even some patients have IUDs that penetrate the uterine cavity and run into their stomachs, and need to undergo laparotomy to take out the IUDs.

3. Hinder other diagnosis and treatment

Older women will inevitably get sick, and some diseases require MRI examination, which is generally not allowed with IUD.

Therefore, [it is always necessary to return it when you come out to mix]. For women who use IUD, since it is put in, it needs to be taken out later.

Don’t take chances and feel that since you don’t feel much, you should stay in the womb first. When you really feel what, I’m afraid you will have a big fight.

Remind women entering menopause that if contraception is carried out through IUD, it is generally recommended to take it out about half a year after menopause.
