[Analysis of sterile male semen of occupational drivers].
OBJECTIVE
To explore the possible correlation between the driver's occupation and male semen quality.


METHODS
Semen samples were collected from 1,223 infertile men (78 drivers and 1,145 non-drivers) and 100 normal men, and their liquefaction, sperm density, sperm vitality, sperm motility and sperm shape were analysed.


RESULTS
The abnormal rates of semen quality in sterile male drivers were significantly higher than in non-drivers(P < 0.05) and in normal men(P < 0.01). The semen abnormal rates in drivers with more than 8 years' driving experience were higher than in those with less than 8 years' driving experience(P < 0.05).


CONCLUSIONS
Driving occupation can result in abnormal semen quality.
