"An
artificial uterus or
artificial womb is a device that would allow for extracorporeal pregnancy by
growing a fetus outside the body of an organism that would normally carry the fetus to term.
An artificial uterus, as a replacement organ, would have many applications. It could be used to assist male or female couples in the development of a fetus. 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.
In 2016, scientists published two studies regarding human embryos developing for thirteen days within an ecto-uterine environment. Currently, a 14-day rule prevents human embryos from being kept in artificial wombs longer than 14 days. This rule has been codified into law in twelve countries.
In 2017, fetal researchers at the Children's Hospital of Philidelphia published a study showing they had grown premature lamb fetuses for four weeks in an extra-uterine life support system." - Excerpt (introductory paragraph) from following Wikipedia page:
