NEW YORK (Reuters Health) - Men who are exposed to organic solvents at work may have lowered sperm counts, according to Canadian researchers.
Among men seen at a single fertility clinic, those with moderate exposure to organic solvents were twice as likely as men with no exposure to have low sperm counts. Those with high exposure were nearly four times more likely to have decreased counts.
And among men seen in a number of Canadian clinics, those with the highest on-the-job solvent exposure were also almost four times more likely to have lowered sperm counts.
Workers exposed to organic solvents and their fumes include painters, dry-cleaning workers, pesticide sprayers and printing press operators.
The findings are published in September issue of the journal Occupational and Environmental Medicine. Dr. Nicola Cherry of the University of Alberta led the study.
Cherry's team evaluated the sperm counts of 656 men who visited a fertility clinic in Montreal between 1972 and 1991, as well as those of another 574 men who visited various fertility clinics in Canada between 1984 and 1987. The researchers classified men by occupations and estimated their exposure to organic solvents.
Among men at the Montreal clinic, sperm counts decreased with increasing exposure to solvents, the investigators found. In the clinics across Canada, men's sperm counts were affected only with high exposure to solvents.
For now, the researchers report, it is unclear whether all solvents may carry such risks at high concentrations. And, the authors note, it is possible that solvent exposure is a marker for exposures to other potentially harmful substances such as lead.
"Exposure to organic solvents is common both at work and in recreational pursuits," Cherry and colleagues conclude. "The results of this study suggest that efforts should be made to identify the compounds hazardous to male fertility, and if the risk is confirmed, to regulate their use."
