With an effectiveness of over 99% it's a wonder that it took this long for IUDs to gain popularity; there's no need to take anything daily, and the pill and other popular forms of contraception have much higher rates of accidental pregnancies, probably due to improper use. IUDs take the human factor out of the equation. According to this article (
http://www.gynecologists.com/news/iuds-doctor-vs-patient/) female obstetricians/gynecologists have a higher rate of using IUDs personally than do their patients, so if the majority of doctors aren't just advocating these devices but actually using them for their own contraceptive needs then it should follow that more women should look at this as a highly effective option.
