The proposal that exposures to environmental or occupational substances may
affect erection ability is a tenable one and would add to a growing list of
pathogenic risk factors associated with erectile dysfunction. Several lines of
evidence gained by clinical epidemiologic and biomedical research
investigations lend support. Several environmental toxicants to include lead,
organic solvents, and pesticides have been implicated as possibly hazardous
agents. Effects on the nervous and hormonal systems have been proposed as the
leading mechanisms by which environmental toxicants adversely impact erectile
function. Synthesis of the current evidence supports a possible risk
association between environmental exposures and erectile dysfunction. However,
scientific support is lacking to establish a direct causal association at this
time. More scientific work is needed to identify specific environmental agents
that may harm erectile function and define their exact mechanisms of action in
this regard.
