This link{http://www.vocalicious.com/empty_arms/empty_arms_mod.html\link} was posted on an adoption message board that I use as a good explaination for friends and family of what it feels like to be infertile. I found it very moving and although not exactly the same as my experience a lot of it was pretty close. Especially the name, I did have years of feeling that there was something missing from my arms, in the same way as my shoulder feels unusually light if I go out without my handbag.
