Fertility clinics can be a double-edged sword. They help couples who have trouble conceiving children naturally. But at the same time, many of these clinics are creating embryos with anonymous sperm donors. In other words, they're creating children who will never know their biological father. One estimate believes 30,000-60,000 American kids were conceived through sperm banks and have anonymous biological dads. This has caused psychological distress for may of the kids wondering who their biological dad is. For many, it's brought on an identity crisis of sorts. As a result, they're searching out their dads through DNA testing and online websites. Such quandaries could be avoided if pro-creation was kept within marriage. After all kids deserve to know their biological mother and father and ideally they'd be raised by both parents.
