In my experience it ' s pretty well known to anyone who plays even rec soccer or watches soccer , but maybe not outside of that population . <| sep |> Right , I know there ' s something with bone marrow . I believe I also read about a technique where they take stem cells that are supposed to become gametes and implant your DNA or something like that . Maybe it was that they wash the DNA out of the cells the same way they take a pig ' s heart and put it in a human body . Which gametes do you think you would want ? Eggs or sperm ? I ' m not sure how much can be done if you want eggs , especially since you would need a surrogate mother . I also think most of the things I ' ve read were about cis women having babies with other cis women . Sorry I can ' t be more helpful here .
