Is it possible to have three biological parents? It is now. A lesbian couple from New Jersey have gotten both of their names listed on a baby’s birth certificate. And in this case, each partner has a biological tie to the child. The woman who carried the child had an egg implanted from her partner. The sperm donor was anonymous, but he is obviously a biological parent as well. As I showed in “Heather Has 3 Parents,” we will shortly see lesbian couples who conceive with non-anonymous male friends attempting to form triple parent families. That will open the door to group marriage. This latest step will only serve to hasten the inevitable.
