When it comes to contraception techniques, some of the popular ones are birth control pills, condoms, and emergency pills. This being said, there are other methods of preventing pregnancy that is as much safe and inexpensive as the above-mentioned ones. IUD or intrauterine device is one of them. These devices can provide protection for five years or more. It’s a shaped device wrapped in copper. Owing to their shape, they are also referred to as Copper-T in the Indian market.        

What is Copper-T?

This is an IUD device and is a modern form of contraception for women. Copper-T is only prescribed to a woman who has already given birth to a baby. Tiny as it may seem, the insertion of this device is invasive in nature that needs the supervision of a medical professional. The Copper-T is inserted into the uterus. A plastic string is attached to the end of the copper-T and is hung from the cervix to the vagina.

How is the device inserted?

The end of the device is inserted into the uterus of the patient with a straw tube that points outward. Once the device is inserted successfully, the copper and the piece of plastic that is embedded inside the plastic takes its effect and start acting as a birth control device. The interesting geometry of this device is because the T-shape gives it enough flexibility to sit inside the uterus and do not move for years.

What are the different types of IUDs available?

Hormonal IUD

This is a variation of copper IUD. The device contains a hormone known as progestin. This, in turn, blocks the egg from fertilizing and implanting on the wall of the uterus.

Copper IUD

This is by far the most commonly used IUD device. It makes the fallopian tube and the uterus produce a fluid that kills the sperm entering the uterus. It possesses copper ions, prostaglandins, white blood cells, enzymes etc that can successfully negate the sperm from fertilizing with an ovum after the intercourse.        

How does copper kill the sperm?

Once the IUD is successfully placed inside the uterus, the copper placed inside the wrapper of the IUD produces copper ions that creates a hostile environment in the uterus for pregnancy. The copper ions mix with the cervix mucus and the uterine fluid. The uterine fluid that is now rich in copper becomes a spermicide and kills sperm whenever it comes in touch with any of them. It can do so because of the toxic nature of copper that is extremely harmful to the sperm. Even If by any accident, a sperm is able to fertilize with an ovum, the copper induced environment within the uterus doesn’t let the implantation of the fertilized egg to take place.    

The effectivity of IUD device?

Once an IUD device is planted inside the uterus, it can successfully protect a woman from pregnancy for about a decade. There are devices that last for a five-year term too. The longevity of the device depends on the manufacturer. The lasting effect of the IUD device makes it a very inexpensive mechanism of birth control. In general, a copper-T can give protection with an accuracy of 98%. If, however, a woman wishes to conceive, she can take it out with the help of a medical professional and get on with the pregnancy with any trouble.
