While I was planning the experiment, I thought that I didn't care much about this risk, albeit for unconventional reasons. (If I was really worried, I could have banked sperm, but I didn't.) It's not that I have no interest in raising children someday. It's more that sperm is cheap. _Optimizing the genetic makeup of the next generation_ is obviously very important.
