Techno-natalism: Geopolitical and socioeconomic implications of emerging reproductive technologies in a world of sub-replacement fertility.

Population is a key factor of national power. Declining fertility rates, especially in major economies, are reshaping global power dynamics by shrinking workforces amidst aging populations. In response, more nations are adopting techno-natalist policies, promoting reproductive technologies ("reprotech") like IVF to increase birth rates. Advances in genetic embryo selection, gene editing, in vitro gametogenesis, and artificial wombs could further enhance these policies by improving birth rates, health, and human capital. This article examines current and emerging reprotechnologies, the policy landscape, socioeconomic and geopolitical implications, and future research directions. By shaping national and global gene pools, reprotech policies and practices offer a paradigmatic case of gene-culture coevolution. If these technologies prove safe and effective, nations that embrace them are likely to gain geopolitical and evolutionary advantages over those that do not.
