Navigating nanotoxicity, ethical challenges, and policy imperatives in human and livestock reproductive research and therapy

Nanotechnology has emerged as a transformative tool in reproductive research and therapy for both humans and livestock. In human medicine, nanomaterials are being explored for targeted drug delivery to treat infertility, enhance assisted reproductive technologies, and improve in vitro embryo production outcomes. These approaches hold significant potential to address infertility, which affects around 15% of couples worldwide. In the livestock sector, nanotechnology offers promising applications for boosting agricultural productivity by optimizing breeding outcomes, improving semen quality, and enabling precise genetic modifications for the production of genome-edited animals. This commentary explores the complex interplay of nanotoxicity, ethical challenges, and policy imperatives in the context of human and livestock reproductive research and therapy. By examining the mechanisms and risks of nanotoxicity, ethical dilemmas in clinical and agricultural settings, and the need for comprehensive regulatory frameworks, we aim to provide a roadmap for navigating this rapidly evolving field. The goal is to balance innovation with safety, ensuring that nanotechnology’s benefits are realized without compromising health, welfare, or public trust.
