I plan doing this in the Netherlands. If possible, I'd have it covered by insurance, but not hopeful about that...
Wanted to say -- first thing I will do is check the quality of my sperm. What if I am shooting blanks or have another problem? Once it is certain that I pay to preserve good stuff, I will bank it.
One of my SF thoughts is maybe in future they will be able to transplant vagina of another woman into me, and that would be my shoot at using own sperm to get bio children. Though I don't think I will live long enough to get there.
