Your men's rights arguments fall apart instantly.  You can donate a kidney all you want but no one can force you to even if it means saving the life of another even if it is your own child - that's the difference.  In none of your examples does a person lose the right to bodily autonomy.

Your argument that men should have a say is also a failure.  The risk of sex for a man is that he could impregnate the woman. Once in the woman, he has no say about what she does then.  She carries the risk of pregnancy or having to terminate.  She carries the burden of being left with a child she may not have wanted but didn't want to terminate. You get off easy by paying for your decision to take the risk of sex because Congratulations! you just became a father.
