Title Male reproductive pattern in a glass producing area
Bibliographic information 1998, Vol. 11, No.3, p.227-234. 24 ref.
Abstract The objective of the study was to evaluate the reproductive pattern among male crystal glassworkers in comparison to other males in a restricted area in the south-east part of Sweden. The comparison of reproductive patterns was made between groups of glassworkers, farmers, and workers of other occupations. As an indicator of fertility, birth rates and time to first child-birth were calculated. Male sex ratios (number of boys/all child-births) were calculated as a measure of reproductive disturbances. The total birth rates as well as the birth rates for sons were slightly decreased among glassworkers when compared to the group of non-farmers/non-glassworkers and significantly decreased when compared to farmers. The total birth rate of the non-farmer/non-glassworker group was also significantly decreased when compared to farmers. Among the glassworkers, the reduction in birth rates was most pronounced among engravers/grinders both in comparison to farmers and others. The results indicate that paternal exposure in crystal glassworks might somewhat negatively affect the male reproduction at least in a historical perspective. Topics: agricultural operations; antifertility effects; epidemiologic study; glass industry; male workers; manufacturing industries; statistical evaluation.
