artificial uterus
An artificial uterus (or artificial womb) is a theoretical device that would allow for extracorporeal pregnancy or extrauterine fetal incubation (EUFI)〔 by growing an embryo or fetus outside of the body of a female organism that would normally internally carry the embryo or 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. Also, it can potentially be used for initiation of fetal development.〔 Furthermore, it could avail for performing, for example, fetal surgery procedures at an early stage instead of having to postpone them until term of pregnancy.〔
==Components==
An artificial uterus would have to provide nutrients and oxygen to nurture a fetus, as well as dispose of waste material. The scope of an artificial uterus (or "artificial uterus system" to emphasize a broader scope) may also include the interface serving the function otherwise provided by the placenta, an amniotic tank functioning as the amniotic sac, as well as an umbilical cord.
