The Catholic Church frowns on anything IVF since this robs a child the chance to be born out of love – a conjugal union between a man and a woman.
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).
