Phthalate Toxicity in Rats and Its Relation to Testicular Dysgenesis Syndrome in Humans

This work describes the relevance of toxicology studies of environmental chemicals, with a focus on phthalates, for a hypothesis that certain human male reproductive disorders and diseases have a common etiology of disturbance of normal development in utero. The Testicular Dysgenesis Syndrome hypothesis in humans has parallels in male reproductive tract abnormalities and microscopic lesions reported for phthalate toxicity in rats. Additionally, this work describes the histological findings of abnormal testicular development (testicular dysgenesis) in rats as compared to those in humans, as well as potential findings in rats at different ages, from the embryo to the adult.

Automated summary

This study explores the toxicology studies of environmental chemicals with a focus on phthalates and its relevance to male reproductive disorders and diseases. The research found similarities in Testicular Dysgenesis Syndrome hypothesis in humans and rats, as well as histological findings of abnormal testicular development in both species.
