Abstract
Purpose: This study aims to investigate the trends in sperm concentration among fertile Chinese males over the past four decades, addressing whether there has been a change in sperm concentration and identifying potential causes.
Methods: The research included 94 Chinese and English literature sources, covering 27 provinces and cities across China, encompassing a total of 14,634 individuals. A least squares linear regression model was applied to analyze sperm concentration data.
Results: The analysis indicated a significant downward trend overall from 1984 to 2023 (P = 8.42e - 10). A single-factor analysis of variance was performed, categorized by the year of sample collection, showing a decline in sperm concentration across each decade of the collection years (P = 1.01e - 08), with the most significant decline noted between 2004 and 2013 (P = 0.0035).
Conclusion: The findings suggest a general decline in sperm concentration among fertile Chinese males over the past forty years, with a more pronounced decline after the twenty-first century, potentially associated with escalating environmental pollution due to heavy industrialization, poor lifestyle habits, and radiation from electronic devices. Further research is essential to elucidate the causes of and broader implications associated with this downward trend.
期刊介绍：
The Journal of Assisted Reproduction and Genetics publishes cellular, molecular, genetic, and epigenetic discoveries advancing our understanding of the biology and underlying mechanisms from gametogenesis to offspring health. Special emphasis is placed on the practice and evolution of assisted reproduction technologies (ARTs) with reference to the diagnosis and management of diseases affecting fertility. Our goal is to educate our readership in the translation of basic and clinical discoveries made from human or relevant animal models to the safe and efficacious practice of human ARTs. The scientific rigor and ethical standards embraced by the JARG editorial team ensures a broad international base of expertise guiding the marriage of contemporary clinical research paradigms with basic science discovery. JARG publishes original papers, minireviews, case reports, and opinion pieces often combined into special topic issues that will educate clinicians and scientists with interests in the mechanisms of human development that bear on the treatment of infertility and emerging innovations in human ARTs. The guiding principles of male and female reproductive health impacting pre- and post-conceptional viability and developmental potential are emphasized within the purview of human reproductive health in current and future generations of our species.
The journal is published in cooperation with the American Society for Reproductive Medicine, an organization of more than 8,000 physicians, researchers, nurses, technicians and other professionals dedicated to advancing knowledge and expertise in reproductive biology.
