Seahorses do it. We’re not seahorses but other then lacking the research is there any fundmentle reason couldn’t be adapted to carry a baby to full term (other then the obvios need for c-section, or YOW!) It’s my understanding that male sex structures are basically based off the same ones as female’s. Just shifted from egg holding to sperm delivery.
Even if they can’t (which I’m guessing is probably) Could prosthetics could be devised? what would the obsticals then? Would male hormone levels screw up development? Would the immune system attack the kid? Would the dude’s body be unable to keep up with the energy requirments? Any other problems?
