This might be something our new resident geneticist is exploring. Why can't Futanari procreate? Is it a genetic disorder? Is it biological? Etc, etc.<br/><br/>Ordinarily, I explain the reason Futanari can't impregnate a woman due to their genetic anomaly. Something about the mutation that causes Futanari also alters their genetics just enough to make them sterile. But, that's me.
