Melamine and Testicular Health: Examining the Risks and Mechanisms of Toxicity

Abstract

Melamine, a nitrogen-rich organic compound commonly used in industrial applications, became infamous during the 2008 Chinese milk scandal due to its association with renal damage and systemic toxicity. Its potential use as a food additive raises concerns about safety, particularly regarding reproductive health.
This review examines melamine’s impact on testicular health, focusing on mechanisms of toxicity, exposure biomarkers, and public health implications. A comprehensive literature review of experimental studies, epidemiological data, and case reports was conducted to assess melamine’s effects on testicular function, identifying patterns of toxicity and research gaps.
Melamine exposure has been linked to adverse effects on testicular morphology, spermatogenesis, hormonal balance, and oxidative stress. Animal studies suggest that mitochondrial dysfunction and inflammation contribute to testicular toxicity, with species-specific differences affecting susceptibility and response.
This review underscores the need for stringent regulatory measures and public health interventions to mitigate melamine’s harmful effects on male reproductive health, advocating for evidence-based strategies to address the risks of widespread melamine exposure.
