FU mass production of semen may not be possible. No one can replicate the natural body elements. Look at blood. Nobody has been successful in reproducing the exact replica though there is artificial plasma available.

Maybe men will be chosen as per their genetic qualities as well as physical looks and prowess and kept in a zoo. Then women probably will have a look around at all the specimens there and chose whose semen they would like.

Hey FU. Start living down buddy and be careful. You look to be the most appetizing specimen for this purpose
