Scientists Keep Human uterus Functioning Outside Body for Experiements

The machine is technically called PUPER, which stands for “preservation of the uterus in perfusion.” But González’s colleague Xavier Santamaria says the team has adopted a nickname for it: “We call it ‘Mother.’”

He sees a future in which a machine like “Mother” will be able to fully gestate a human, all the way from embryo to newborn. It could offer a new path to parenthood for people who don’t have a uterus, for example, or who are not able to get pregnant for other reasons.

Put the uterus into an optimized breeding robot, cut the gestation time by 3 months and you would never have to hear how hard giving birth is. You could easily plan your parenthood.

I hope you are not serious. There is much more to gestation then what a machine can do.

Maternal-Fetal Attachment (MFA) delineates the emotional, cognitive, and behavioral aspects that mothers develop toward the unborn baby during pregnancy. The literature indicates that optimal attachment in pregnancy represents a protective factor for the mother-child attachment bond after birth and child development outcomes. To date, there are few studies that have investigated associated factors of MFA...We found out that perceived maternal and paternal care had significant direct effects on maternal-infant bonding during the pregnancy period when controlling for some confounders, including gestational age and mother age among others. .. - https://pmc.ncbi.nlm.nih.gov/articles/PMC9885764/

The Surprising Truth of How a Baby’s Cells Live Forever Inside Their Mother: The Fetal Microchimerism Bond
Once considered rare, through various research and studies, fetal microchimerism is now believed to exist in all pregnant women and can stay within mothers for decades. This biological phenomenon occurs when small amounts of genetically different cells are transferred from one person to another. Scientists believe microchimerisms happen in blood transfusions and organ transplants, but it is most common in pregnancy when small numbers of fetal cells are transferred to a pregnant woman.
Maternal cells can also be transferred to the preborn baby, particularly impacting the development of the child’s brain and immune system.
There are two types of microchimerisms during pregnancy: fetal microchimerism (when fetal cells transfer to the mother) and maternal microchimerism (when cells from the mother transfer to her preborn baby).
“The situation is more complex” because a preborn baby can acquire fetal cells from its mother that she “acquired during a previous pregnancy,” according to authors of an article on Science Direct. Maternal microchimerism may aid in the developing baby’s immunity. A mother’s antibodies also protect her child. They are generated by her immune system and delivered to her preborn baby by the placenta while she is pregnant, and then after birth, a child can still receive them through the mother’s breast milk, helping protect the infant from pathogens.

The sharing of cells appears to help bond mother and child emotionally as well as physically.

“There is evidence that these fetal cells can even integrate into and influence the maternal brain,” stated Jennifer Wright, MD, in her article “Maternal-Fetal Bonding.” “There is an ongoing development of maternal-fetal bonding that tends to strengthen and mature throughout the pregnancy.”

Induced abortion doesn’t ‘cut the cord,’ so to speak, between a woman and her preborn child. “This exchange of cells occurs very early in pregnancy and is actually increased in instances of induced abortion,” wrote Dr. Wright....

The cell-sharing between mother and developing child influences both of them psychologically and physiologically.

Fetal microchimerism and maternal microchimerism benefit the mother and her preborn child. Studies show cell transference usually begins between the fourth and sixth week in a woman’s pregnancy and increases significantly throughout her pregnancy, “reaching its maximum level in the days before childbirth.” - https://preborn.com/fetal-microchimerism-bonding/

The bond between a mother and her unborn child begins at the cellular level during pregnancy, as fetal microchimerism allows cells from the fetus to enter the mother's body, creating a lasting connection that influences both emotional and physical well-being. This exchange of cells not only strengthens their bond but also plays a critical role in the mother's health and the child's development.

The Maternal-Child Bond: Why is it Important to Understand? The maternal-child bond refers to the biochemical, physical and emotional bond that exists between nd postnatal child in the "four" trimesters of pregnancy. - https://mcgrath.nd.edu/assets/393701/expert_guide_on_maternal_child_bond.pdf
