What does the Catholic Church say about surrogate motherhood for couples who cannot get pregnant?

Surrogacy is not a moral option. The Catechism of the Catholic Church states: 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 (CCC 2376).
