The Catholic Church teaches that IVF is morally unacceptable because it separates the marriage act from procreation and establishes the domination of technology over human life. The Church’s teaching is based on the 1987 Vatican document “Donum Vitae,” which distinguishes between treatments that assist the marital act in conceiving a child and those that replace the marital act. IVF is considered contrary to God’s plan for marriage and children, as it often involves the death or freezing of embryonic children. The Church emphasizes that the gift of human life must be actualized in marriage through the specific and exclusive acts of husband and wife, in accordance with the laws inscribed in their persons and in their union.
