Disappearing sperms and changing climate: correlating decreasing semen quality and population dynamics within the Sustainable Development Goals framework

Abstract

Background Recent studies have reported a significant decline in human semen quality worldwide, raising concerns about climate change and its extensive effects on human health and biodiversity.Methods This article investigates the correlation between deteriorating semen quality and changing climate conditions, within the context of the United Nations Sustainable Development Goals (SDGs). It aims to explore the linkage between decreasing semen quality and climate change, and to understand its implications for population dynamics, reproductive health and sustainability.Results Integrating findings within the SDGs framework, the study emphasises SDG 3 (good health and well-being), SDG 13 (climate action) and SDG 15 (life on land). A multidisciplinary approach, incorporating data from environmental science, epidemiology and demography, is used to statistically analyse global and regional trends in semen quality against climate variability indicators, such as temperature fluctuations and pollution levels. Preliminary findings indicate a strong correlation between adverse climate conditions and reduced semen quality, suggesting potential impacts on fertility rates and population health. The research highlights the importance of climate action (SDG 13) in protecting human reproductive health and ensuring population stability (SDG 3), while emphasising the interconnectedness of ecosystem health and human well-being (SDG 15).Conclusion The article calls for integrated policy responses addressing climate change and reproductive health as interconnected challenges, advocating for enhanced cross-sectoral collaboration to achieve the SDGs through comprehensive strategies encompassing environmental protection, reproductive healthcare and population management for a sustainable future.
