The idea of growing babies outside the body started with alchemists and became a feminist debate
The earliest vision of artificial human gestation comes from alchemy: in 1572 Paracelsus described a recipe for growing a tiny human, a homunculus, in a flask. In the late 1880s, incubators shown at World's Fairs displayed premature babies in glass boxes, and doctors claimed they could eventually support the second half of pregnancy outside the body. Those early incubators depended on nurses who tended them around the clock. The term ectogenesis was coined by the biologist J B S Haldane in 1923. Feminist writers then debated whether artificial wombs would liberate women or give control of reproduction to men.
Incubators keep a premature baby warm, humid and enclosed, mimicking the conditions of the womb. Early versions were heated boxes that needed constant human adjustment, so the machine was never fully autonomous.
The history shows that neonatal incubators are a direct ancestor of today's experimental artificial-womb research. It also explains why the question of who controls reproduction remains part of the debate.
The term ectogenesis was coined by J B S Haldane in a 1923 speech to the Cambridge Heretics Society.
background
An artificial womb or artificial uterus is a device that allows for extracorporeal pregnancy, by growing a fetus outside the body of an organism that would normally carry the fetus to term. This can potentially be performed as a switch from a natural uterus to an artificial uterus, thereby moving the threshold of fetal viability to a much earlier stage of pregnancy. In this sense, it can be regarded as a neonatal incubator with very extended functions. It could also be used for the initiation of fetal development. An artificial uterus could also help make fetal surgery procedures at an early stage an option instead of having to postpone them until term of pregnancy.
An artificial uterus or incubator can also serve as a tool for wildlife conservation and de-extinction by eliminating the need for surrogate animals and mass-increasing numbers for critically endangered species such as the sand tiger shark. In addition, some recently extinct species can only be conceived through an artificial womb, as they are too distinct from their closest living relatives.
