This is exactly why I banked. Not because I wanted children, but because I didn't know if I didn't want children.
I'm not sure if ther is ever not a single sperm produced by the body after years on hormones, no way enough to conceive naturally, but I would guess the may be the odd one floating around down there.
Does anyone know if it is a true 100% certainty that your body no longer produces anything?
Probably depends too the drugs each of us are using.
Oh and yea you should try not to worry to much about it now, it doesn't change anything. And as others have said the opportunity to addopt is there and it can be really amazing to think what you have done for poor child that was left all on their own

I think I may adopt too in the future :3
