What is an intrauterine device (IUD)?

An Intrauterine Device (IUD) is a small, T-shaped contraceptive device that is inserted into the uterus to prevent pregnancy.

• It is a long-term and reversible method of birth control.
• There are two main types:
  1. Copper IUD – releases copper ions that make the uterine environment unfavorable for sperm.
  2. Hormonal IUD – releases progestin hormone that thickens cervical mucus and sometimes suppresses ovulation.
• IUDs prevent fertilization by blocking sperm from reaching or fertilizing an egg, and in some cases, they also prevent implantation.
• They can remain effective for 3 to 10 years, depending on the type.
• It is one of the most reliable and widely used contraceptive methods.
