The use of human artificial gametes and the limits of reproductive freedom

Recent developments in generating gametes via in vitro gametogenesis (IVG) from induced pluripotent stem cells (iPSCs) and their successful use for reproductive purposes in animals strongly suggest that soon these methods could also be used in human reproduction. At least two questions emerge in this context: (a) if a legislator should permit their use and (b) if ethical claims emerge that support their provision, e.g., by public health care systems. This urges an ethical reflection of the new reproductive options this technique might offer. Since the concept of reproductive freedom is a key aspect for the ethical evaluation of artificial reproductive technologies (ARTs), it is necessary to analyze if the new possibilities emerging from IVG fall within the scope of this concept. The results may constitute a morally relevant difference between different imaginable applications of IVG and potentially justify differences in claims to access this technology.
