Types of IUDs

A group practice with locations in East Brunswick and Hillsborough, New Jersey, Brunswick Hills OBGYN provides compassionate care to women of all ages. For those in their childbearing years, the trusted doctors and advance practice nurses at Brunswick Hills OBGYN offer the full range of birth control options, including intrauterine devices (IUDs).

An IUD is a plastic device that is inserted into the uterus. Shaped like a T, an IUD has a string on the end that protrudes from the opening of the cervix. The manner in which an IUD prevents pregnancy depends on which of the two types on the market that the patient chooses.

The copper IUD is wrapped in wire made of copper, which prompts the fallopian tubes and uterus to produce chemicals that are toxic to sperm. This type of IUD, sold by the brand name Paragard, can be worn for a maximum of 10 years and does not alter hormone levels in the body.

Hormonal IUDs, most often sold under the brand names Mirena and Skyla, use hormones that make the cervical mucus thicker, which prevents sperm from making their way into the uterus. These hormones also alter the thickness of the uterine lining so that if conception does occur, the embryo does not have a hospitable place to implant. The Mirena IUD can stay in place for up to five years, and the Skyla IUD should be replaced after three years.
