In an effort to identify possible adverse male reproductive effects in artillery crewmen, a cross sectional, collaborative, epidemiologic study was performed using data from 81 soldiers. The soldiers included artillery crewmen, military intelligence specialists, and environmental control subjects. There were no statistically significant relationships identified between exposure status and blood lead (7439921) concentrations. The microwave exposed soldiers showed a significant decline in sperm count and total sperm count and a difference approaching statistical significance in percent motile sperm and linearity. The average sperm count drop was from 38 to 15 million sperm/milliliter. This occurred in some of the most important semen quality measurements taken. A significant interaction was noted between self perceived fertility concern and exposure status. For lead exposed soldiers, those with a fertility concern had significantly lower sperm count and percent normal forms and a marginally significant total count. Those with no concern had no significant changes.
