*sigh* not surprised.... i'm a little young to be doing anything permanent (i'm still 19), and I know it, but I wouldn't be surprised if 5 or 10 years down the road I wanted to. However, it seems there are plenty of docs who think there's something "wrong" with you if you're female and you *gasp* don't want children...
... that said, I guess it's unfair to assume that's the reason they restricted the clinical trials. There could be a reason they only want people who have given birth (easier insertion etc?)... I just didn't see one in perusing article, so I am suspicious.
