In their Making Sense of Bioethics newsletter, the National Catholic Bioethics Center takes a look at the complicated moral and ethical problems raised by surrogacy:
Sometimes when there is infertility in marriage, couples make the decision to seek out the services of a surrogate in order to have a child. A surrogate is a woman who agrees to be implanted with an embryo produced by in vitro fertilization (IVF) and to hand over the newborn baby to the couple upon completion of the gestation and birth. In recent years, gestational surrogacy has become a multi-million dollar industry, attracting a broad clientele ranging from married couples to single women, gay couples to anyone else with the desire for a baby and the ability to finance the undertaking. Surrogacy raises grave moral concerns, and powerfully undermines the dignity of human procreation, particularly when it comes to the women and children involved in the process.
