are they any industrial uses for sperm
The Sperm Whale is an example of sperm being worth as big a wad as you can come by. Before petroleum they were a main source for lamp oil.
But even better, ladies, is what the stuff is still used for. Many of you smear whale cum on your faces daily. It used to be in most cosmetics but has been replaced by cheap chemicals. Nothing feels as soft and luxurious as a handful of whale juice...I can't help wonder who was the first to try it!
And YES Virginia, they have the organ to match the body. Down right scary..
I wish I did, too.
Now, to answer the real question. Yes, if you mean use it AFTER it has left the body. That is what a sperm bank does. For instance, you find you have testicular cancer. You sperm are still good but the testicles must go (rare for two, I know) so, if you want kids later, put the sperm on ice. They are SALVAGED!!!
If you mean,"can dead,dry sperm be "resurrected", not without divine intervention.". If it were possible, a guy asking such a question would wake to find a whole country of people sprouting from last night's gym sock...whack on...
