In this paper, we explore how members of the public invoke science fiction tropes and references in response to the topic of complete ectogenesis (where the entire development of a fetus takes place outside of the human body in an artificial womb environment) and, to a lesser extent, genome editing. This paper addresses a critical research gap as fiction is central to how the public make sense of new technologies. This research is timely, as human clinical trials of artificial placenta and womb technology are expected to start within the next few years. We argue that gauging public opinion on this technology is a critical early step in understanding how the public might respond to such new technologies, should they become available in the near future and be presented in a particular fashion.Using corpus linguistic techniques, we analysed a large dataset of 15 548 YouTube comments (382 057 words) made in response to a video that depicts a fictional artificial womb facility, which went viral in December 2022 when some viewers believed it to be real. We identified several statistically significant trends, as commenters associated the video with science fiction, horror and dystopian fiction, while also making specific reference to , and (Clone Wars). These observations reveal how popular science fiction narratives serve as a key point of reference and that they stand as a powerful warning in the public imagination, and as a potential barrier to public acceptance of new reproductive technologies-despite the potential benefits for social justice and reproductive rights. Our findings therefore have implications for how scientific developments are communicated to the general public.
