What does the Church teach about IVF?

The Catholic Church teaches that in vitro fertilization, or IVF, is morally wrong. This judgment applies even when the husband and wife use their own sperm and egg and sincerely desire a child.

Why IVF is wrong. God designed marital intercourse to unite husband and wife while remaining open to the gift of new life. These unitive and procreative meanings should not be deliberately separated. In IVF, conception is produced through a laboratory procedure rather than arising from the spouses' bodily self-gift. A child has the right to be conceived through the marital act, received as a gift, and not produced through a technical process (CCC 2376-2378).

Why embryos matter. Human life must be respected and protected from conception (CCC 2270). IVF commonly creates several embryos so that some can be selected for transfer. Others may be frozen, discarded, subjected to testing, donated for research, or lost during the process. Each embryo is already a distinct human being with an immortal destiny, regardless of size, health, or stage of development. Deliberately destroying or treating embryos as biological material is gravely wrong (CCC 2274-2275). Even an IVF procedure designed to avoid destroying extra embryos would still wrongly replace the marital act.

The dignity of children conceived through IVF. A child conceived through IVF bears no guilt and has exactly the same God-given dignity as every other child. The moral judgment concerns the actions of adults and the reproductive process, never the worth of the child. Parents should love, protect, baptize, and raise that child with gratitude. They should not be treated with shame or suspicion.

What treatments may be acceptable. The Church supports medical care that identifies and treats the causes of infertility while helping the marital act achieve conception. Depending on the procedure, this can include hormonal treatment, surgery, treatment of endometriosis, and methods of fertility awareness. A treatment assists marital intercourse when conception still results from the spouses' own act. Procedures involving donor sperm, donor eggs, or surrogacy add further wrongs because they introduce a third party into parenthood and violate the child's right to be born of his or her married parents (CCC 2376).

For couples carrying this cross. Infertility causes real grief, and the Church calls Christian communities to respond with compassion, not easy answers (CCC 2374). Couples may consider morally sound treatment, adoption, foster care, or other forms of generous service. A Catholic physician or moral theologian faithful to Donum Vitae and Dignitas Personae can help evaluate particular procedures before treatment begins.
