Abstract

A reductive reading of Humanae vitae seeks to limit its appeal to a ban on contraception. In truth, however, it offers a vision of human sexuality and conjugal love with broad and enduring relevance. In setting forth the intrinsic complementarity and irreducibility of the unitive and procreative dimensions of the conjugal act, Paul VI has given us a hermeneutical key for assessing many contemporary ethical dilemmas in human reproductive medicine. From this perspective, this article seeks to apply the logic of Humanae vitae to several real-life scenarios confronted by medical practitioners, educators, and ethicists working in the field of fertility and reproductive health. These include a consideration of the ethics of prescribing hormonal contraceptives, the possibilities of investigating male infertility, issues of cooperation in counseling and assisting conception in same-sex relationships, the ethics pertaining to assisted reproductive technology, the contested case of prenatal adoption, and the application of double-effect reasoning. On the occasion of the fiftieth anniversary of the promulgation of Pope Paul VI's encyclical Humanae vitae, this article seeks to defend its enduring relevance to modern-day society, through application of its reasoning to contemporary dilemmas in reproductive medicine. It considers real cases of the ethics of prescribing hormonal contraceptives, of investigating male infertility, of cooperating in counseling and assisting conception in same-sex relationships, of ART, of prenatal adoption, and the application of double-effect reasoning.
