A Boring Dystopia

Good news boys, if we're willing to use women this way, we can actually do the same for men! This is one unique sexual reproduction horror story that can in theory be inflicted on both sexes!

Pregnancy without a uterus, impossible! You say. But ectopic pregnancies are a thing. We all start out as parasites. As an embryo develops, it looks for a surface of flesh rich in blood vessels to latch onto. The primary function of the uterus is to provide an inner lining that is sort of a "disposable surface." The inner lining is rich in blood vessels, the ideal environment for a zygote to latch onto and grow from. The embryo can integrate its blood vessels with the uterine lining and thoroughly mess those up. Then after pregnancy the whole inner lining is just sloughed off. That in inelegant terms is the uterus - an organ that produces a nice safe surface for the zygote to latch onto that won't harm the person carrying the pregnancy.

But, things don't always go well. If a zygote somehow tears through the uterine wall, then ectopic pregnancy, pregnancy outside the uterus, can result. And this a serious life-threatening medical condition. The fetus as it develops will latch onto not the intended uterine surface, but the vital abdominal organs. Giving "birth" in this case is done surgically, and it's more akin to cutting out a cancer than a healthy live birth.

But while it hasn't been tried due to the obvious health risks and huge medical ethics issues, there's little reason to think that ectopic pregnancies couldn't be carried in a male admomen. DNA and chromosomes shouldn't be a barrier. The placenta that the fetus grows is evolved to prevent the fetus from being rejected like a donor organ. It's not like mothers and infants share their DNA.

So in theory we could use men in vegetative states as one-time use surrogates. There has been research proposed and papers written on the possibility of trans women carrying children via uterine transplant, but this method, deliberate artificial ectopic pregnancy, is in principle a lot simpler. You don't need to transplant a delicate organ and find a way to carry a pregnancy while taking anti-rejection drugs. You just implant an embryo in the surrogate abdomen and let it go to town. Let it latch in to whatever internal organs it wants. Then after nine months, just cut open and discard the surrogate father.

It wouldn't be as simple as just implanting an embryo. The pregnant vegetative man would likely need to have his hormone profile monitored and heavily manipulated. But this is easy enough. Testosterone production could be nuked by simple castration, and erogenous estrogen and progesterone could then be introduced as needed before and during the pregnancy. After the pregnancy, it is unlikely the man would survive. So this is a one time deal. But if we're OK treating people in persistent vegetative states like resources to be exploited, I see no reason to throw out half of our potential surrogate population simply because they happen to be men.
