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.

Paragraph 2373
2373. Sacred Scripture and the Church's traditional practice see in large families a sign of God's blessing and the parents' generosity.162
Paragraph 2374
2374. Couples who discover that they are sterile suffer greatly. "What will you give me," asks Abraham of God, "for I continue childless?"163 and Rachel cries to her husband Jacob, "Give me children, or I shall die!"164
Paragraph 2375
2375. Research aimed at reducing human sterility is to be encouraged, on condition that it is placed "at the service of the human person, of his inalienable rights, and his true and integral good according to the design and will of God."165
Paragraph 2376
2376. Techniques that entail the dissociation of husband and wife, by the intrusion of a person other than the couple (donation of sperm or ovum, surrogate uterus), are gravely immoral. These techniques (heterologous artificial insemination and fertilization) infringe the child's right to be born of a father and mother known to him and bound to each other by marriage. They betray the spouses' "right to become a father and a mother only through each other."166
Paragraph 2377
2377. Techniques involving only the married couple (homologous artificial insemination and fertilization) are perhaps less reprehensible, yet remain morally unacceptable. They dissociate the sexual act from the procreative act. the act which brings the child into existence is no longer an act by which two persons give themselves to one another, but one that "entrusts the life and identity of the embryo into the power of doctors and biologists and establishes the domination of technology over the origin and destiny of the human person. Such a relationship of domination is in itself contrary to the dignity and equality that must be common to parents and children."167 "Under the moral aspect procreation is deprived of its proper perfection when it is not willed as the fruit of the conjugal act, that is to say, of the specific act of the spouses' union .... Only respect for the link between the meanings of the conjugal act and respect for the unity of the human being make possible procreation in conformity with the dignity of the person."168
