An artificial uterus, sometimes referred to as an "exowomb", [13] 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 ...
In immunology, passive immunity is the transfer of active humoral immunity of ready-made antibodies.Passive immunity can occur naturally, when maternal antibodies are transferred to the fetus through the placenta, and it can also be induced artificially, when high levels of antibodies specific to a pathogen or toxin (obtained from humans, horses, or other animals) are transferred to non-immune ...
Ectogenesis of human embryos and fetuses would require an artificial uterus. An artificial uterus would have to be supplied with nutrients and oxygen from some source to nurture the fetus, as well as dispose of waste material. There would likely be a need for an interface between such a supplier, filling this function of the placenta. As a ...

Each male rat was castrated, surgically joined to a female, and given a transplanted uterus. The researchers then implanted embryos in both the uterus of the male and female parabionts. Pregnancies were allowed to develop until two days before the end of a full term, and were terminated by caesarean section. The researchers studied 46 such ...

Chorioamnionitis, or intraamniotic infection, is an infection of any combination of the amniotic fluid, placenta, fetus, fetal membranes, or decidua. [13] The gold standard for diagnosing chorioamnionitis is via a gram stain, glucose level, or culture of the amniotic fluid obtained via amniocentesis. [13]
Labor is separated into 4 stages. The first stage involves latent phase and active phase separated by the dilation of the cervix for 6 to 10 cm. The second stage is the pushing stage. The third stage involves the delivery of the placenta. And the last stage is the contraction of the uterus. [21]
