text: why can't men get pregnant?   "actually there has been a few recorded cases of male pregnancy and men giving birth twas the inspiration behind a movie starring arnold schwarzenegger"  i disagree.  the inspiration was that some women have delivered live babies which developed outside the womb; in the peritoneal cavity.  in these cases, the placenta of the ectopic pregnancy embeds itself into the walls of various abdominal organs.  the situation is very dangerous.  commonly, ectopic conceptions end in massive haemorrhage, long before the foetus has any chance of surviving outside the mother's body.  her life is endangered, as the bleeding is huge, and sometimes is hard to diagnose, in time to save her life.  anyhow, there has been speculation that an embryo from ivf could grow in a man's abdomen; clearly, a uterus is not an absolute requirement.  i think no ethics board could condone such an attempt, as his life would be endangered if the pregnancy ended in haemorrhage preterm.  [well, it would be endangered anyhow, but it is extra yukky, if the baby dies too; the usual outcome!]  i suspect that a male's body would also be unable to suppress his immune system enough to avoid rejection of the foreign tissues of the conceptus.  i am not sure, but i wonder if females are better able to do this complex immunological trick!  btw, all these cases must be dealt with surgically; it is major abdominal surgery!
