Coil File: Everything You Need to Know About Coil

Updated: Mar 1, 2023

Coil, also called intrauterine device is one of the frequently used birth control methods. It is also one of the most commonly used methods among the public health, as it can be used in the longer term compared to other birth control methods. It is being very effective makes it another reason public chose this method.

But like other obgyn issues and diseases, this is one of the topics that is not very talked about. We're here to talk about myths.

So, let's talk about the coil.

How Does The Coil Work?

Because the coil is a material coming from outside of the body, it is also perceived by the uterus as a foreign substance. For this reason, it creates a reaction similar to inflammation in this region, neutralizing the sperm that reaches the uterus and preventing pregnancy, while the ovulation process continues.

Contrary to popular belief, it is not for staying in the way of eggs, but originally a method to allow sperm to be neutralized. Another misconception popularly known is that women who have given birth before cannot use coils. But this information is also not true. Women who have not given birth can also use the coil as a method of birth control.


What Are The Side Effects Of Coil?

Copper coils, for instance, can prolong the amount of bleeding, and the day of bleeding and can cause the bleeding period to be more painful. These two side effects are also common in the first months after the spiral is inserted and can be treated by doctors with painkillers and inflammation relievers.

But one of the situations that should be considered is that if these drugs are used, there is no improvement in the pain and bleeding process, and in such cases, it is necessary to consult a doctor.

Why Should The Coil Be Removed?

Women often prefer to remove the spiral due to pain and bleeding irregularity. But in addition, when antibiotics cannot be responded to and inflammation cannot be treated, it is also recommended to be removed by doctors.

Can Coil Fall Out?

If the coil is not inserted into the uterus by the appropriate method, it falls or changes position within the first days. It can also fall spontaneously in cases of unexpected infection or pregnancy. This condition is often noticed by the person and you should consult a doctor at the appropriate time.

Hormonal Coils

Hormonal coils, which are widely used in the world contain the hormone progesterone. The biggest advantage of these coils is that they reduce the amount of bleeding and pain in spite of copper coils. Although they neutralize sperm, they have also been shown to reduce the amount of ovulation. It also prevents sperm from reaching the uterus thanks to the uterine plug, and also significantly reduces the development of pelvic infection.

Coil As a Method Of Birth Control

When Does the Protection of the Coil Begin and End?

As soon as the coil is inserted, its protection begins, and as soon as it is removed, its protection ends. Like every birth control, the coil does not provide 100% protection, but we can still say that it is a very effective method of birth control. Observation of pregnancy within 1 year after the installation was recorded as 1-3%.


When You Shouldn't Get the Coil?

  • Unregular menstrual bleeding

  • Known pregnancy and suspected pregnancy

  • If there is a known cervical infection or a genital infection

  • If you are allergic to copper

  • If you have Willson syndrome

  • If the Pap smear result is abnormal

  • If cervical erosion is present

  • If there is a clotting disorder

  • If you have a malignant tumor

When Should The Coil Be Inserted?

Doctors suggest inserting it on the first days of the bleeding after additional tests because there is no pregnancy and because the opening of the cervix is present. It can also be placed within the first 48 hours or 40 days after normal delivery. It can also be worn immediately after conditions such as miscarriage or abortion.


If You Have Coil When Should You Consult A Doctor?

  • Abnormal bleeding

  • Menstrual disorder

  • Severe pain and cramps

  • Bouts of fever and chills

  • Feeling the spiral during intercourse

Can You Get Pregnant When Using a Coil?

When using a coil, you can become pregnant, and when it is noticed, the spiral must be removed immediately. However a miscarriage can occur when removing a coil, so if the pregnancy does not want to be terminated, the curettage method is used. In cases where pregnancy progresses, it is not possible to remove the coil, but pregnancy can continue with the coil in many cases.

Does Coil Cause Ectopic Pregnancy?

It has been observed that ectopic pregnancy is more common in women who use coils compared to women who do not use coils, and this statistic is higher in women who use hormonal coils.


Does the Coil Cause Infertility?

Because the coil increases the risk of infection, it can cause adhesions of infections such as tube and chlamydia, gonorrhea, and thus cause infertility if normal tissue loss occurs.

That’s a really interesting article. I believe the Mirena/Hormonal coil is also prescribed in addition to HRT in some cases.
