Great thread.   
I married late (40) and never felt a biological clock ticking before then. I'm the youngest of six, and all my siblings had children, so there was never any feeling that the family name/genetics wasn't going to carry on.    
That said, my wife and I did want kids and tried. It didn't work. Surprisingly, we weren't devastated. We decided that we would live our own lives and be the best aunts/uncles, etc. we could be.    
So many times I've thought that fate worked out for the best. As much as I love children, maybe there was a reason we didn't have kids. We're good at being who we are. Maybe we weren't supposed to be parents.   
To be honest, I probably would have felt differently if my siblings hadn't all had children. But knowing the family gene pool is carrying on, I'm OK with it.
