IUD/Coil

IUD/Coil

The coil, also known as an intrauterine device (IUD), is a small T-shaped contraceptive device that is inserted into the uterus by a healthcare provider to provide long-term birth control and, in some cases, reduce menstrual bleeding.

These are two different types of intrauterine contraceptives that offer effective, long-term birth control options. Here's an overview of each:

Copper Intrauterine Device

(Copper IUD)

• How it Works:

  • The copper IUD is a small, T-shaped device that is inserted into the uterus by a healthcare provider. It works primarily by releasing copper ions, which are toxic to sperm, thereby preventing fertilization. It can also affect the uterine lining, making it less receptive to implantation of a fertilized egg.

• Effectiveness:

  • The copper IUD is one of the most effective forms of contraception, with a failure rate of less than 1%. Once inserted, it can provide protection against pregnancy for up to 10 years, depending on the specific brand and type.

• Non-Hormonal:

  • Unlike many other forms of birth control, the copper IUD is hormone-free. This makes it a suitable option for those who cannot or do not wish to use hormonal contraceptives.

• Quick Reversibility:

  • Fertility can return quickly after removal of the copper IUD, making it a reversible option for those who want to become pregnant in the future.

• Side Effects:

  • Some may experience heavier menstrual bleeding and more painful periods after getting a copper IUD. However, these side effects vary from person to person.

Mirena Intrauterine System

(Mirena IUD)

• How it Works:

  • The Mirena IUD is also a T-shaped device inserted into the uterus by a healthcare provider. However, it differs from the copper IUD in that it releases a low dose of the hormone levonorgestrel, a type of progestin. This hormone thickens cervical mucus, making it difficult for sperm to reach the egg, and it can also affect the uterine lining.

• Effectiveness:

  • The Mirena IUD is highly effective, with a failure rate of less than 1%. It provides protection against pregnancy for up to 5 years.

• Hormonal:

  • Since it contains a hormone, the Mirena IUD may have additional benefits beyond contraception, including reducing menstrual bleeding and cramps. Some experience lighter or even absent periods while using it.

• Reversibility:

  • Like the copper IUD, fertility can return quickly after removal of the Mirena IUD, making it a reversible option for future pregnancy.

• Side Effects:

  • Common side effects can include irregular bleeding, especially in the first few months after insertion. Some may also experience hormonal side effects, such as mood changes or breast tenderness.

Choosing between the copper IUD and the Mirena IUD depends on individual preferences, medical history, and lifestyle factors. It's important to have a discussion with a healthcare provider to determine which option is best suited to your needs and to receive proper counselling on the risks and benefits of each. Both IUDs are highly effective at preventing pregnancy and have their own advantages, so the choice often comes down to personal considerations.
