To be fair Birr, despite what some might assert, a uterus manages to perform every necessary function to incubate a new life, and generally does so with excellent performance and minimal maintenance. All that's needed to supply the fetus is a slightly greater food intake. As such, barring medical necessity in those cases were miscarriage is a risk to mother, child or both, there's no need to use a uterine replicator, while the psychological factors on the side of the parents should not be discounted in child rearing. Given that, you know, the body does do a lot of things to the brain to make you want to take care of a noisy, messy pile of trouble that's incapable of attending to itself and will be incapable of attending to itself for the next decade or so at the very minimum.
And not just to the mother.
