How Does an IUD work?

This tiny device prevents pregnancy by stopping the sperm from reaching the uterus which prevents the fertilization of eggs.

Types Of IUD:-

There are five different brands of IUDs available in the market which are divided into two types.

Hormonal IUDs

  • Hormonal IUDs release synthetic versions of progesterone which is known as progestin. Progestin also is known as levonorgestrel is the same hormone which is used in many birth control pills. Progestin helps to thicken the mucus in the cervix which makes it impossible for the sperm to reach the egg.
  • Another mechanism of progestin is that it thins the lining of the uterus makes it difficult for the egg to implant in the uterus because it doesn’t allow the sperm to reach the uterus and fertilize the egg.

Four different brands of hormonal IUDs as follows:-

  • Mirena:- It can help to prevent pregnancy for up to 6 years.
  • Kyleena:- It can help to prevent pregnancy for up to 5 years
  • Liletta:- It can work as long as 4 years.
  • Skyla:- It can work up to 3 years.

Copper IUDs or Non-Hormonal IUDs

  • In the case of copper IUDs, hormones are not used. Instead of hormones copper is used which damages sperm and prevents it from getting to the egg. It also creates an immune response in the body which stops developing healthy eggs. If an egg was produced it destroys it completely.
  • The only brand of copper IUDs is ParaGard. Many doctors use this method of contraception if there is a need for emergency contraception. The copper IUDs usually last for about 10 years and its effects can last longer than this period of time.
