IUD* (Intrauterine Device)

How does it work?

  • Small t-shaped device is inserted into the uterus.
  • There are two types of IUDs:

1. Hormonal IUD:

  • Made of plastic and contains a small amount of the hormone progesterone.
  • The hormone is slowly released at low levels, which thin the uterus lining and thickens cervical mucus making it difficult for the sperm to fetilize an egg and attach to the uterus wall.
  • Effective for 3 to 5 years depending on the brand used.
  • 99% effective.

2. Copper IUD:

  • Made of plastic and copper.
  • Copper acts as a spermicide and destroys sperm.
  • Prevents the egg from meeting the sperm and attaching to the wall of the uterus.
  • Can be inserted as emergency contraception within 7 days of unprotected intercourse.
  • Effective for 3-10 years depending on the brand used.
  • 99% effective.

Advantages

  • There is nothing to do before you have intercourse.
  • A good method for people who are breastfeeding (after six weeks postpartum).
  • It is immediately reversible with not long-term effects on fertility.
  • Reduced cost over time compared to other methods.

Disadvantages

  • No protection against STIs, including HIV.
  • May cause irregular menstrual periods.
  • Requires a visit to a health care provider.
  • Non-hormonal IUDs may cause increased bleeding during periods, periods lasting longer or more cramping.
  • Initial expense.
