Abstract

This article defends the morality of heterologous embryo transfer (HET) against those who claim that HET is wrong because it makes a woman a mother through someone other than her spouse. I contrast genetic parenthood with gestation to show that gestation alone does not make someone a mother in the focal sense. Genetic parenthood gives rise to the full obligations of parenthood—i.e., makes someone a parent in the focal sense—because the child’s relationship to his genetic parents is (1) permanent, (2) identity-defining, and (3) initially (at conception) the child’s closest human relationship. While the gestational relationship importantly influences the child’s identity, it lacks the unique closeness, permanence, and identity-defining nature that characterize the genetic parent-child relationship, and therefore gives rise only to temporary obligations akin to those of a foster parent. Recognizing these crucial differences between gestation and procreation helps to show that HET is not inherently immoral.
