Abstract:	Objectives: The aim was to determine whether occupational exposure to polycyclic aromatic hydrocarbons (PAHs) in men has adverse effect on semen quality. Methods: Forty-eight coke-oven workers, including 16 topside-oven (TO) workers and 32 sideoven (SO) workers, were studied. Ambient PAHs exposure, urinary 1-hydroxypyrene (1-OHP) levels, and parameters of semen quality were determined. Results: TO workers had significantly higher ambient PAHs exposure (3,436.1 +/- 3,411.0 vs. 1,123.1 +/- 1,829.3 ng/m(3), P < 0.01), urinary 1-OHP levels (207.8 +/- 176.4 vs. 54.0 +/- 44.8 mu g/g, P < 0.001), frequency of oligospermia (18.8 vs. 0%, P < 0.05), and morphological abnormality in sperm (32.3 vs. 14.6%, P < 0.01) than SO workers. Among cigarette smokers, TO workers had significantly higher rates of DNA denaturation in spermatozoa (alpha T) and percentage of sperm with increased DNA denaturation (COMP alpha T) levels than SO workers (246.2 +/- 49.5 vs. 198.1 +/- 30.3 for alpha T; 34.8 +/- 14.4 vs. 19.3 +/- 13.9% for COMP alpha T, P < 0.05). There was a positive correlation between urinary 1-OHP and alpha T, COMP alpha T, and abnormal sperm morphology and a tenfold increase in urinary 1-OHP associated with a 2.35-fold increase in alpha T, as well as a 1.07-fold increase in percentage of sperm with abnormal morphology. Conclusions: A potential risk of sperm dysfunction should be considered for workers occupationally exposed to high levels of PAHs. Cigarette smoking may aggravate this risk. Urinary 1-OHP can be used as a biomarker predicting sperm dysfunction.
