Thanks for the post, Marie55 but, I can't help but feel lectured by it, when I thought these boards were created for knowledge, and support.

I feel like (by the responses I've gotten), some women think it is insensitive of me, to be curious about what's going on with her. I am completely understanding of the reasons she doesn't feel like telling me exactly what is going on with her, which is why I don't ask. I do not see any harm in my trying to find out SOMETHING for myself, since I've known about this for years, and have been unable to find out (I think we all are curious about certain things, and do research, just for our own personal knowledge--there is nobody who can outrightly say that my researching this will hurt her

). I have thought about it many times (and continue to do so), what it would be like to be unable to carry a child of my own (and I know that husbands also play a part in infertility, sometimes), and I would be completely devastated by it, since I want them so badly (so, no lecturing needed there). Thank you for your list of possibilities of what it could be--that is all I was asking for, from the people who may have an idea.
Just a question though--why on earth would I not "accept" my friend for who she is, simply because she may not be able to carry a child???
