IVF as commonly practiced raises serious biblical concerns: it typically produces more embryos than are transferred, resulting in destruction or indefinite freezing of human embryos. If life begins at conception (Psalm 139:13-16, Jeremiah 1:5), each embryo is a human person. Natural cycle IVF and embryo adoption present different ethical profiles. Christians should not enter IVF without thorough engagement with these questions.
In vitro fertilization involves retrieving eggs, fertilizing them in a laboratory, and transferring resulting embryos into the uterus. Standard protocols typically produce 8-15 embryos per cycle and transfer 1-2, with the remainder frozen indefinitely or discarded. If life begins at conception, each unused embryo is a human person made in the image of God (Genesis 1:27, Psalm 139:13-16).
Psalm 139:13-16 describes God as knitting David together in his mother's womb. Jeremiah 1:5 states God knew Jeremiah before he was formed in the womb. Luke 1:41-44 records that John the Baptist leaped in the womb in response to Jesus. The consistent witness of the church through history is that human life is sacred from conception.
If these premises are correct, the routine creation and destruction of human embryos in standard IVF is not a secondary ethical question. It is a matter of the sanctity of human life.
Embryo destruction: Most IVF cycles produce more embryos than are implanted. The American Society for Reproductive Medicine estimates over 1 million embryos are currently in frozen storage in the United States. Selective reduction: When multiple embryos implant, some clinics recommend terminating one or more. Preimplantation genetic testing: PGT-A screens embryos and discards those with chromosomal abnormalities including Down syndrome.
Infertility is a genuine grief. Hannah's prayer in 1 Samuel 1, Rachel's anguish in Genesis 30, and Elizabeth's experience in Luke 1 acknowledge this pain. Natural cycle IVF (which produces only as many embryos as are transferred) presents a different ethical profile. Embryo adoption, in which a couple adopts existing frozen embryos, is widely affirmed by Christian ethicists.
