Between innovation and precaution: how did offspring safety considerations play a role in strategies of introducing new reproductive techniques?

Silences, omissions and oversimplification? The UK debate on mitochondrial donation

Drawing on scholarship from ignorance studies, this paper uses the case of the UK debates on mitochondrial donation (2012-2015) to emphasize the importance of deploying an analysis of ignorance that goes beyond medical and safety concerns when scrutinizing debates or campaigns around new reproductive technologies. In contrast to what happened with previous reproductive health treatments or drugs, the potential medical risks of mitochondrial donation were explicitly acknowledged and examined during its public and parliamentary discussions. However, I show, using the concepts of 'acknowledged unknowns' and 'ignored knowns', how the attention drawn to the medical risks contributed to obscuring the assessment of its economic and social impacts by silencing key knowledge regarding the limitations of mitochondrial donation in relation to the potential beneficiaries, the scope of the techniques, their alternatives and their costs. This article therefore calls for more systematic use of an integrated analytical framework of ignorance to be applied in the field of reproductive public policies, paying particular attention not only to the ways that medical risks are addressed, but also to the type of knowledge and disciplines this allows to silence or side-line in the framing and assessment of new biotechnologies.

The path toward ectogenesis: looking beyond the technical challenges

BACKGROUND

Breakthroughs in animal studies make the topic of human application of ectogenesis for medical and non-medical purposes more relevant than ever before. While current data do not yet demonstrate a reasonable expectation of clinical benefit soon, several groups are investigating the feasibility of artificial uteri for extracorporeal human gestation.

MAIN TEXT

This paper offers the first comprehensive and up to date discussion of the most important pros and cons of human ectogenesis in light of clinical application, along with an examination of crucial ethical (and legal) issues that continued research into, and the clinical translation of, ectogenesis gives rise to. The expected benefits include advancing prenatal medicine, improving neonatal intensive care, and providing a novel pathway towards biological parenthood. This comes with important future challenges. Prior to human application, important questions have to be considered concerning translational research, experimental use of human fetuses and appropriate safety testing. Key questions are identified regarding risks to ectogenesis' subjects, and the physical impact on the pregnant person when transfer from the uterus to the artificial womb is required. Critical issues concerning proportionality have to be considered, also in terms of equity of access, relative to the envisaged application of ectogenesis. The advent of ectogenesis also comes with crucial issues surrounding abortion, extended fetal viability and moral status of the fetus.

CONCLUSIONS

The development of human ectogenesis will have numerous implications for clinical practice. Prior to human testing, close consideration should be given to whether (and how) ectogenesis can be introduced as a continuation of existing neonatal care, with due attention to both safety risks to the fetus and pressures on pregnant persons to undergo experimental and/or invasive procedures. Equally important is the societal debate about the acceptable applications of ectogenesis and how access to these usages should be prioritized. It should be anticipated that clinical availability of ectogenesis, possibly first as a way to save extremely premature fetuses, may spark demand for non-medical purposes, like avoiding physical and social burdens of pregnancy.
