Abstract
This research employs network psychometrics to elucidate the connection between religiosity and the meanings ascribed to in vitro fertilisation (IVF), using a representative sample of Polish Roman Catholics (N=874). Although Poland is known as a country with high indicators of religiosity, studies show that Polish Roman Catholics generally hold positive or neutral views of IVF. Of particular significance is the emergence of "sin" as the central node within the network of meanings associated with IVF. Furthermore, "artificial fertilisation" surfaces as a particularly ambiguous meaning. Beyond its scientific contribution, this article offers practical implications for shaping health policy pertaining to IVF.
