Use As Emergency Contraception
It was first discovered in 1976 that the copper IUD could be used as a form of emergency contraception(EC). The copper IUD is the most effective form of emergency contraception. It is more effective than the hormonal EC pills currently available. The pregnancy rate among those using the copper IUD for EC is 0.09%. It can be used for EC up to 5 days after the act of unprotected sex and does not decrease in effectiveness during the 5 days. An additional advantage of using the copper IUD for emergency contraception is that it can be used as a form of birth control for 10–12 years after insertion.

Famous quotes containing the word emergency:
“War-making is one of the few activities that people are not supposed to view “realistically”; that is, with an eye to expense and practical outcome. In all-out war, expenditure is all-out, unprudent—war being defined as an emergency in which no sacrifice is excessive.”
—Susan Sontag (b. 1933)
