Contraception has given women more control over their family planning and life choices. However, despite many options, women still face challenges and worries when choosing the right method. Concerns about safety, side effects, and costs make the decision complex. These struggles are crucial to address as they affect women's health, emotions, and reproductive rights. In this discussion, we explore the various issues women encounter while seeking reliable and suitable contraceptive solutions for their individual needs.

What Is an Intrauterine Device?

An intrauterine device (IUD) is a birth control device that is placed inside a woman’s uterus to prevent pregnancy. It lasts for up to three to 12 years, and is one of the most effective methods of birth control, and, depending on the type, has a failure rate of about 0.1 and 2.2 percent after one year of use.

There Are Two Types of IUD -

  • Hormonal IUD - Contains copper.

  • Copper IUD - Contains hormone progestogen.

What Is A Copper T?

An intrauterine device with a T-shaped plastic body with copper wrapped around its stem is called a copper T or intrauterine coil. It is used as a birth control method and can also be used as an emergency contraceptive if inserted within five days after unprotected intercourse. It can be used by women of all ages, irrespective of any previous pregnancies. If the individual decides to get pregnant, fertility returns quickly after removing the device.

How Does Copper IUD (Intrauterine Device) Work?

Copper IUD works by affecting the sperm and preventing them from fertilizing the egg. It is believed that copper increases the levels of copper ions, prostaglandins, and white blood cells in the uterine and tubal fluids, thus acting as a spermicide.

It also affects the transportation of eggs in the fallopian tube and also changes the lining of the uterus, making it difficult for an embryo to attach and grow.

How Effective Is Copper IUD (Intrauterine Device) as Birth Control?

Copper T is one of the best birth control methods available because there is no chance of making any mistake. It is not a pill, so you do not have to remember to take it every day. Once you get a copper IUD, depending on the type, you will have 24 hours of protection every day for three to 12 years, which is 99 percent effective.

How Effective Is Copper IUD (Intrauterine Device) as Emergency Contraception?

Copper T, if placed within 120 hours (five days) of unprotected sex, is almost 99.9 percent effective in preventing pregnancy.

How Is Copper IUD Inserted?

It can be inserted at any time during the menstrual period, but the best time is right after the period. The cervix is softest during this period, and the chances of the lady being pregnant are less. The doctor will take a thorough history to know if you have any risk factors for infections, and he or she will conduct a physical examination.

During the day of insertion, the doctor will determine the position of the uterus and will hold the vagina open with an instrument called a speculum. Then the cervix and uterus are stabilized, and the IUD is placed using a narrow tube. Short strings attached to the device hang down from the uterus to the vagina. This string is used to ensure that the device is in place later and allows easy removal by the doctor.

What Are the Advantages of Copper IUD (Intrauterine Device)?

A copper IUD (intrauterine device) is one of the most advisable, safe, and effective ways to prevent birth control.

  • They are 99 percent effective.

  • It can be used for up to ten years.

  • No need to take any pills.

  • It can be used while breastfeeding.

  • You can get pregnant quickly after you get it removed.

  • It is comparatively less expensive, as you do have to spend anything apart from the time of insertion.

What Are the Side Effects of IUD (Intrauterine Device)?

Some of the side effects are:

  • Perforation - In rare cases, while inserting the IUD, it can perforate the uterus wall and damage other internal organs. Surgery is needed to remove the IUD.

  • Infection - In the first 21 days after insertion, there is a risk of developing the pelvic inflammatory disease (PID). The chances of PID increase with the presence of infections like chlamydia and gonorrhea.

  • Expulsion - In 2.2 to 11.4 percent of users, the copper IUD can spontaneously be expelled from the uterus. The signs of possible expulsion are abnormal vaginal discharge, cramping, abdominal pain, spotting, pain during sex, and lengthening or absence of the strings.

  • Cramping - Due to dilation of the cervix during insertion of the device, most women have pain and cramping.

  • Heavy Periods - Most women experience heavier periods after inserting the device. There is approximately a 20 to 50 percent increase in menstrual bleeding, which is one of the leading reasons for IUD removal.

  • Spotting Between Periods - In the first few months after placing the IUD, some people experience irregular bleeding and spotting.

  • Pregnancy - The rate of ectopic pregnancy is high with IUDs (intrauterine device). If pregnancy occurs while using IUD, there are more chances of miscarriage and early delivery.

  • Problems With the Strings - Some men report feeling the string during sex. In such cases, the string is trimmed a little, but then it makes it difficult for the women to check for signs of expulsion.

When Is Copper IUD (Intrauterine Device) Contraindicated?

Copper IUDs are not recommended for the following women:

  • Pregnant women.

  • Women with untreated cervical or uterine cancer.

  • Women who have unexplained vaginal bleeding.

  • Women with uterine abnormalities.

  • People with multiple sexual partners because of the risk of sexually transmitted infections.

  • Women with copper allergy.

  • Pelvic infection patients.

  • Wilson’s disease patients.

  • In cases of pelvic tuberculosis.

What Are Frameless IUDs?

A frameless IUD does not have the conventional T-shaped plastic frame which makes up the body of the IUD. This change was made to reduce the side effects like expulsion and discomfort after insertion.

Do Copper IUDs Prevent STDs (Sexually Transmitted Disease)?

No, a copper IUD is only a birth control method and does nothing to prevent sexually transmitted diseases (STDs). So it is advisable to use condoms and avoid multiple sexual partners to prevent getting infected.

When selecting a birth control method, it is essential to have a conversation with your gynecologist. Your doctor can consider your specific health condition and other factors to guide you towards the most suitable option. Fortunately, you can conveniently post your queries and book real-time video consultations online to seek advice from a medical professional.


Prioritizing your reproductive health requires thoughtful consideration and expert guidance. By consulting with your gynecologist and utilizing online resources for real-time video consultations, you can make informed decisions about the best birth control method that aligns with your individual needs and ensures your well-being. Empower yourself with knowledge and professional support to take charge of your reproductive choices confidently.
