Future Research

Our exploration into immune modulation of Leydig cell steroidogenesis revealed that oxidative stress related perturbation of Leydig cell mitochondria mediates the abrupt cessation of testosterone production at the level of cholesterol transfer to the steroidogenic pathway. This mechanism is central to a host of pathologies known to present with hypogonadism including alcoholism, diabetes, aging and certain environmental endocrine disruptors. Our laboratory has initiated studies in oxidative stress effects of alcoholism, diabetes and aging as well as environmental agro and industrial compounds such as dioxin, polycyclic armoatic hydrocarbons, and conazoles.

Industrial Relevance

Therapeutic intervention for workplace exposure to endocrine disruptors that cause decreased testosterone
