I'm curious what problems you have in mind. Of my friends who I know use an IUD, 4 out of 4 say some variation of "how could you consider using anything else?" The only complaint that I heard from this admittedly small sample is a day's worth of discomfort following insertion.
As far as IUD's, let's not forget there are two types: paragaurd (copper) IUD and Mirena (levonorgestrel eg hormonal) IUD. There are different side-effects associated with both although I have anecdotally heard that paragaurd's side effects are mild compared to oral contraceptives. Should someone not wish to use hormonal BC or if they cannot for various medical reasons-->paragaurd is what you are stuck with. And its great in many ways (no babies, no babies and no babies), but many women experience periods that last over a week and spotting in between as well as extremely painful cramps. I was on it for 6 years and I'm so happy I finally got it removed. In summary, IUD's are of course a great form of BC, but that doesn't mean we shouldn't pursue more options. I don't think I'm stating anything earth shattering when I say, women wouldn't mind more non-hormonal based BC options.
