How does copper iud work?
In a copper IUD, the horizontal bar of the device’s T is wrapped in thin copper wire, and each bar of the T has a copper collar (7). The copper releases copper ions into the uterus. The ions change the fluids in the fallopian tube and uterus, making them inhospitable to sperm (1).
