499. Why are artificial insemination and artificial fertilization immoral?

They are immoral because they dissociate procreation from the act with which the spouses give themselves to each other and so introduce the domination of technology over the origin and destiny of the human person. Furthermore, heterologous insemination and fertilization with the use of techniques that involve a person other than the married couple infringe upon the right of a child to be born of a father and mother known to him, bound to each other by marriage and having the exclusive right to become parents only through each another.

500. How should children be considered?

A child is a gift of God, the supreme gift of marriage. There is no such thing as a right to have children (e.g. "a child at any cost"). But a child does have the right to be the fruit of the conjugal act of its parents as well as the right to be respected as a person from the moment of conception.
