Copper IUD

The main benefits of the copper IUD are its convenience and non-hormonal nature. This makes it suitable for women who worry about the side effects of hormonal contraceptives or are uncomfortable with disruption to their menstrual cycles which may occur with certain other forms of hormonal contraception.

The main drawback of the copper IUD is that it results in heavier and potentially more painful menstrual periods. This makes it unsuitable for women who already suffer from heavy or painful periods. Insertion of the copper IUD is generally safe and simple but may come with some side effects like bleeding and discomfort and a low risk of more serious complications like infection or uterine perforation.

The copper IUD does not contain any hormones while the hormonal IUD (e.g. Mirena) contains a progestin hormone called levonorgestrel, which is released in small amounts gradually and regularly into the walls of the uterus. The hormones from the hormonal IUD result in a lighter menstrual period, or in some women, their menses may stop altogether. With the copper IUD, you will still get your period regularly but it may be heavier than before.

The copper IUD does not interfere with PAP smears at all, as it sits within the uterine cavity. The IUD string which protrudes through the cervix into the vaginal canal will not affect a PAP smear either. Women with the copper IUD can and should continue with their regular PAP smears.
