The whole female body is adapted for pregnancy, it's not simply a function of the womb and ovaries. For example, the pelvis is a different shape from males, and hormones released in pregnancy loosen the joints to allow the baby to grow and the pelvis to shift to accommodate the growing baby. There are many more anatomical and physiological specialisations like this that only apply to the female body. This suggestion that there will be no issues if ovaries and a womb are fitted inside a male body is entirely unproven. The only way to prove it is to do the experiment and attempt to bring a baby to term, but this is a huge unknown and the ethical issues here are immense. How many of these tiny, developing humans will die during this experimentation phase, or be permanently disabled for life? How much of their suffering is acceptable to fulfil this questionable agenda of enabling males to gestate a human? Why should the desires of these men override the human rights of infants to not be experimented upon?
