biogenetic child
adj.— «With egg donation, science has succeeded in, if not extending women’s fertility, at least making an end run around it, allowing older women who, for a variety of reasons (lack of money, lack of partner, lack of interest, lack of partner’s interest) didn’t have children in their biological prime—as well as younger women with dysfunctional ovaries—to carry and bear babies themselves. It has given rise to the mind-bending phrase “biogenetic child,” meaning a child who is both biologically and genetically related to each of its parents, by, for the first time in history, separating those components.» —“Your Gamete, Myself” by Peggy Orenstein New York Times July 15, 2007.
