BACKGROUND: Few studies have investigated reproductive health effects of contemporary agricultural pesticides in boys.
OBJECTIVES: To determine the association between pesticide exposure and reproductive health of boys.
METHODS: We conducted a cross-sectional study in rural South Africa of boys living on and off farms. The study included a questionnaire (demographics, general and reproductive health, phyto-estrogen intake, residential history, pesticide exposures, exposures during pregnancy); and a physical examination that included sexual maturity development ratings; testicular volume; height, weight, body mass index; and sex hormone concentrations.
