Transcript of Artificial Wombs
K How does it work? An artificial uterus or womb allows pregnancy outside of the body of a female to occur. In a lab an artificial uterus is made using cells from a woman's uterus. A fertilized egg is then implanted into the uterus where it can grow and flourish outside of a woman's body.
More recently, she grew a human embryo, for ten days in an artificial womb. Her work is limited by legislation that imposes a 14-day limit on research project of this nature. As complicated as it is, her goal is a functioning external womb. Medical Benefits (why do we need it?) help infertile couples
enable premature babies to survive
create an alternative to surrogacy
help women unable to carry their own babies
provide a safe, healthy gestational environment – free from drugs and alcohol.
give gay couples new fertility options What will it replace? -Traditional baby making methods
-Women carrying children Japanese professor Dr. Yoshinori Kuwabara of Juntendo University has successfully gestated goat embryos in a machine that holds amniotic fluid in tanks. Dr. Helen Hung-Ching Liu succeeded in growing a mouse embryo, almost to full term, by adding engineered endometrium (inner lining of uterus) tissue to a bio-engineered, extra-uterine “scaffold" in 2003. Who's developing it? Dr. Hung-Ching Liu is studying the beginning stages of pregnancy. Her team has removed cells from a woman's uterus and by using hormones and growth factors, they have been able to grow the cells. The model dissolves over time, and the artificial womb continues to grow. Dr. Yoshinori Kuwabara of Japan has developed a rectangular artificial womb made from acrylic plastic and filled with heated amniotic fluid. Target Market infertile women (women who can't have children)
women who give birth to premature babies Functional or Theoretical? Functional! But not with human embryos yet. Dr. Yoshinori Kuwabara Dr. Hung-Ching Liu Cornell University's Center for

Japan Dr. Hung-Ching Liu Artificial Wombs The technique, called extra-uterine fetal incubation, involves placing the goat fetus in a plastic container of warmed, amniotic-like fluid, where it is supplied with nutrients through a tube inserted in its umbilical cord. In fact, scientists at the Chinese Academy of Medical Sciences have undertaken experiments to implant artificial wombs in the abdomen of a man. This would allow men to be the "mothers" instead of a female. BABYTRON machines and “motherless births” are not on the immediate horizon. But may be something used in the near future. Imagine telling your child they were born from a machine. With artificial wombs, this may be our future. In-vitro fertilization (IVF) -begins with this process, except it is implanted into an artificial uterus instead of a real one. once the egg grows enough, the womb begins to grow from the artificial uterus where it receives nourishment and continues to grow Why did we choose this topic? Impact on my Life -replace natural births (no labor)
-if unable to have children, another option other than surrogacy and adoption
artificial womb instead of This He has done experiments using goat fetuses. The goat fetuses were transferred to the machine after three weeks of gestation. (Equivalent to transplanting a human fetus at the end of the first trimester) 2 What is it used for?
