Hello everyone! We have MFI & we're going to try IUI#1 hopefully this cycle. When I had my CD3 U/s & bloodwork, they said my estradiol was a little elevated. It was 79. They said that they like to see it at 50 or under. My RE said it could just be b/c i'm getting older (only 30 though) and the ovaries are not working as well anymore. My friend looked up info which said even between 80-100 is borderline, not necessarily high. Do others have thoughts on what they've heard?? I also read though that my FSH being low enough to be "normal" could be artificially bringing down the estradiol #, so it could actually be higher (but that was just one possible scenario in reading). Thanks!
