The lifecycle of sex dolls—from manufacturing and customization to end-of-life disposal—raises numerous ethical dilemmas. During production, questions about labor practices, environmental impact, and sourcing of materials are paramount. Manufacturers must ensure that production processes uphold workers’ rights and minimize ecological harm. Throughout use, ethical considerations include user behavior—such as consent, respectful interaction, and avoiding misuse—and the societal messages conveyed. At the end of a doll’s lifespan, disposal presents environmental and moral challenges, especially given the materials used, which may not be biodegradable or recyclable. Improper disposal could contribute to environmental degradation, raising questions about corporate responsibility and consumer awareness. Additionally, there are ethical concerns about the potential for dolls to be repurposed into replicas of real individuals without consent, which can infringe on privacy rights and dignity. Responsible lifecycle management involves implementing sustainable practices, encouraging ethical consumer behavior, and establishing clear guidelines for disposal. Addressing these dilemmas requires a comprehensive ethical framework that considers environmental sustainability, respect for human dignity, and social responsibility at every stage of the doll’s lifecycle.
