Artificial gametes, derived from stem cells, have the potential to enable in vitro fertilization of embryos. Currently, artificial gametes are only being generated in laboratory animals; however, considerable efforts are underway to develop artificial gametes using human cell sources. These artificial gametes are being proposed as a means to address infertility through assisted reproductive technologies. Nonetheless, the availability of artificial gametes obtained from adult organisms can potentially expand the possibilities of reproduction. Various groups, such as same-sex couples, post-menopausal women, and (...) deceased donors, could potentially utilize artificial gametes to conceive genetically related offspring. The advent of artificial gametes raises significant bioethical questions. Should all these reproductive scenarios be accepted? How can we delineate the range of future reproductive choices? A normative bioethical framework may be necessary to establish a consensus regarding the use of human artificial gametes. This review aims to present the current state of research on the biological roadmap for generating artificial gametes, while also summarizing proposed approaches to establish a normative framework that delineates ethically acceptable paths for reproduction.

I defend two collapsing or reductionist arguments against Weak Pro-Natalism (WPN), the view that procreation is generally merely permissible. In particular, I argue that WPN collapses into Strong Pro-Natalism (SPN), the view that procreation is generally obligatory. Because SPN conflicts with the dominant view that procreation is never obligatory, demonstrating that WPN collapses into or entails SPN establishes epistemic parity (at least as concerns reproductive liberty) between WPN and Anti-Natalism (AN), the view that procreation is always impermissible. First, I distinguish (...) between two moral goods: the good of procreation itself and the good of procreative potential. Second, I contend that the average moral agent is obligated to assist needy children via adoption, fostering, or other financial or interpersonal support. Third, I present the first collapsing argument: If an agent’s justification for not assisting needy children is preservation of their resources (financial or interpersonal) for their actual future offspring, that justification is preserved only if they eventually and actually procreate. Thus, their eventual procreation is morally obligatory, and SPN follows. Fourth, I present the second collapsing argument, which assumes procreative potential as the relevant good: If an agent’s justification for not assisting needy children is preservation of their resources for their potential future offspring, that justification holds only if (a) the objective or subjective valuation of the opportunity is of the relevant type and valence to justify not assisting needy children and (b) the agent sincerely values the opportunity. Fifth, I argue that (a) is unsatisfied and that while (b) is satisfied in most cases, it entails that most agents are obligated to desire or be behaviorally disposed to pursue procreation for themselves (i.e., SPN). Thus, I conclude that both actual procreation and procreative potential are either insufficient justifications for not assisting needy children or that they entail obligatory pro-reproductive attitudes or behaviors.

The dispute between the transgender-rights movement and “gender-critical” activists represents a stark division in British public discourse. Although the issues of contention are numerous and require their own philosophical treatment, a core metaphysical concern underlies them. Gender-critical activists, such as Kathleen Stock, tend to argue that recognizing trans women as women requires erasing the category of biological sex. This implies that all trans women are male, and thus recognizing them as women rips female biology from the root of the category (...) “woman.” In this article, I argue that this view is mistaken. As exogenously produced sex characteristics should count toward a person's sex classification, all trans women are female. (shrink)
