I understand totally. I always get people, when I say that my DH has no sperm, then trying to tell me how you never know, it could just happen. Their husband had low sperm count & it still happened, etc etc. Ummm, a world expert in the field has literally cut open DH's balls, and searched through every bit of them with a microscope & couldn't find a single sperm. But sure, it might just happen naturally .... because it did for you. I know people mean well, but they really seem to have trouble grasping that not everybody has the same situation.
