Copper IUD

The copper IUD is 99% effective at preventing pregnancy and is the recommended birth control option among the three methods discussed. The copper IUD achieves high effectiveness without introducing hormones into the body, making it preferable over the hormonal IUD. The copper IUD is a small T-shaped device inserted into the uterus. The copper IUD reduces the fertilization potential at the uterine lining, making it less hospitable for egg implantation. The copper IUD releases copper ions that act as a spermicide by disabling sperm before it can reach the egg. The copper IUD can cause pelvic inflammatory disease, creating inflammation within the uterus. The copper IUD can worsen menstrual cramping and increase the severity of heavy periods.
