So a plastic surgeon thinks he can control or bypass the delicately balanced endocrinology and immunology which allows a healthy pregnancy to persist and survive and produce a healthy baby at the end?
I’d be extremely dubious about this. As PP have said, we don’t have all the answers regarding causes of miscarriage and birth defects, the effects of micro plastics or hormones in drinking water, fetal alcohol syndrome, thalidomide, Zika virus etc so who knows what the effects of a hormone battle between male hormones and exogenous hormones might cause.
In medicine isn’t the basic theory first do no harm? It’s one thing to try to cure a diagnosed disease of an existing biological process. Quite another to engineer something so counter-natural. Using human fetuses as the guinea pigs. It’s disgusting when you think about it.
Also, in the aims of not discriminating, why would a man even need to claim to be a tw, could a gay couple push for this too? So they’d get the only bit of a surrogate they needed, without the human being attached?
Meanwhile women and babies die in some parts of the world for want of a midwife or some antibiotics.
