A problem for same-sex couples who want to be parents exists. How can they both be biologically related to their child?
This problem may very shortly be solved with vitro gametogenesis, or IVG. IVG will allow the child to have DNA from both parents.
Through IVG, scientists can create stem cells that can be used for reproduction. These stem cells can be grown into eggs or sperm!
Although the process has only been attempted on mice, scientific publications such as the New Scientist are optimistic it could work in humans as well.
For lesbian couples, one partner would supply stem cells, which would be converted into sperm, while the other partner would supply an egg. The two would be combined to form the embryo.
The opposite would occur for male couples, with one of them supplying the stem cells that would form an egg. A surrogate womb would still be necessary.
This process could benefit other forms of families as well. Single parents or even multiplex parents, which are more than two parents of the same child.
This form of impregnation still needs to be tested more. "You'd still have a lot of safety studies to do in animals before you get to people," says bioethics professor Arthur Caplan. Still, this is an exciting hope for nontraditional couples looking to start a family!
