Ectogestation technology, when feasible, will permit fetal development within an artificial womb. Ectogestation is termed ectogenesis when it is full (gestation occurs exclusively within an artificial womb post in vitro fertilisation) or partial (artificial gestation occurs during the course of in vivo gestation, post a caesarean-like fetal transfer). In what follows, I explore the implications for the gestational versus moral parenthood debate recently spotlighted by Benjamin Lange1 for various alternative uses of ectogestation compared to the baseline case of in vivo gestation.

I contrast ectogestation in four different contexts with in vivo gestation followed by vaginal delivery. I document the relevant outcomes, burdens and harms in particular, to the gestating mother, the biological father, the fetus and the child into whom it will develop. The focus on harms in considering intraparental claims to parenthood follows Lange’s focal article1: importantly, however, I focus not on harms from separation from the gestational procreator (as in adoption cases) but instead on harms arising from the use of ectogestation in various forms.

I note at the outset, how, for each case discussed below, I indicate opportunities for each biological parent to establish voluntarism-based claims to moral parenthood. In the analyses, except where specifically noted, the default implication is that it is …
