More people may be able to share genetic parenthood of a baby with another person. Human skin and blood cells are being turned into eggs and sperm cells. In mice, they have done this. There are more possibilities for biological parenthood if they can do it in people.
Same-sex couples should be allowed to have genetically related children. Imagine if you could turn the skin of one man into an egg cell andfertilize it with his partner's sperm to make an embryo.
The same technology can be used to create another sperm or egg cell from that embryo. Sex cells from two couples could be used to create an embryo with four genes.
The embryos created in the middle step would be the parents of the baby, making things even more confusing. The babies would be orphans according to some scientists. Others think they would have four parents.
Genetics isn't what makes a parent. The person who takes care of the child is not the supplier of genetic material.
It is possible to do this without being a child's biological parent. The data was collected by Vasanti Jadva at University College London. More than 200 children were born around 2000. Egg donation, sperm donation, and a surrogate resulted in 51 of the 80 children being born. There was no change in the well-being of the children.
By the age of two, the children that came from donors and surrogates showed no difference in their development. They had more positive relationships with their parents than the typical ones.
They didn't pay much attention to the circumstances of their conception. Jadva said at the meeting in Amsterdam that by the time they were 21 years old, most of them were not worried about having been born through egg or sperm donation.
