[Leslie Carol Botha: More legalized rape on women. The study indicated that IUD’s are a highly effective method of contraception after unprotected intercourse when inserted post-coitally. Unnecessary infliction of pain on women. Those who have had IUD’s will concur. Mental/emotional stress plus physical pain. Oh, yeah – another win situation for women. Sounds like they are marketing IUD’s on a desperate demographic of women]
IUDs Effective as Emergency Contraception

Intrauterine devices (IUDs) seem to be an effective method of emergency contraception, with a failure rate of less than one per thousand, according to a meta-analysis.
In a review of 35 years of data in which IUDs were inserted after unprotected intercourse, 99.86% of overall women did not become pregnant, reported Kelly Cleland, a research scientist at Princeton University in New Jersey, and colleagues in Human Reproduction.
Unintended pregnancy is a signiﬁcant problem, with at least 36% of pregnancies worldwide and nearly half of pregnancies in the U.S. being unintended, the authors noted in their introduction. Emergency contraception is a popular method for preventing unwanted pregnancy, with oral methods such as levonorgestrel (Plan B) and ulipristal acetate (Ella or EllaOne), among the leading medications used.
Although IUDs are another option, negative experiences with the Dalkon Shield in the 1970s led to years of low IUD use, the authors pointed out. But one of the major advantages of copper IUDs is that after placement for emergency contraception, the device can be left in and will continue to prevent pregnancy for at least a decade.
Cleland’s group conducted a systematic review intended to provide a current estimate of the efficacy of IUDs as emergency contraception. They found 274 articles, in English and Chinese, published by August 2011 but narrowed the list to 42 studies published from 1979 to 2011.
The authors noted that they included studies published in Chinese because, according to China’s family planning commission, 53% of married women surveyed in 2009 who used contraception opted for an IUD.
