The aim of the study is to evaluate if the occupational exposure to urban stressors could cause alterations in 17-β-estradiol (E2) plasma levels and related disorders in male traffic police compared with a control group. After excluding from the study, the subjects with the principal confounding factors, traffic police and controls were matched by age, working life, Body Mass Index (BMI), smoking and drinking habit. A total of 171 male traffic police and 171 controls were included in the study. In traffic police, mean E2 values were significantly lower versus controls (P < 0.001). The distribution of E2 values in traffic police and controls was significant (P < 0.001). No significant differences were found in percentage of traffic police versus controls concerning the following questionnaire items: fertility and mental health diseases. Our results suggest that the occupational exposure to chemical urban stressor, interacting with and adding to the psychosocial ones, could alter plasma E2 concentrations in male traffic police compared with a control group. According to our previous researches on other neuro-immune-endocrine parameters, E2 could be used as an early biological marker, valuable for the group, to be used in occupational set even before the onset of the pathologies.

Key Words: 17-β-estradiol • endocrine disruptors • male reproductive health • traffic police • urban stressors
