  A woman may still supply nutrients and dispose of waste products if the artificial uterus is connected to her. She may also provide immune protection against diseases by passing of IgG antibodies to the embryo or fetus.
  
  Artificial supply and disposal have the potential advantage of allowing the fetus to develop in an environment that is not influenced by the presence of disease, environmental pollutants, alcohol, or drugs which a human may have in the circulatory system. There is no risk of an immune reaction towards the embryo or fetus that could otherwise arise from insufficient gestational immune tolerance. Some individual functions of an artificial supplier and disposer include:
  
  Theoretically, animal suppliers and disposers may be used, but when involving an animal's uterus the technique may rather be in the scope of interspecific pregnancy.
