Children are persons with inherent dignity. They are not commodities to be bought, sold, or manufactured. It is beneath our dignity to be manufactured in a laboratory. It reduces a person to a commodity to be bartered over-- look at how there are now lawsuits between spouses regarding who “owns” the embryos, etc. It is its own form of slavery-- ownership of a person and the idea that one has a “right” to produce a child to one’s specifications by any means available. We have no such right over another person.
It is also a violation of the dignity of the child when born of parents not their own. They have a natural right to a family consisting of their own mother and father. To see the harm in depriving a child of this witness all the groups that are searching for their “sperm donor” fathers or egg donor mother-- the quest to know “who they are” and “where they come from” is part of their human psyche. Children are harmed psychologically when they are produced in such a manner and deprived of this basic human right.
