title: [Occupational damage to fertility in welders].
abstract: The aim of the present study is to establish whether there is difference in the quality of the sperm of welders in comparison with members of other professions without potential occupational risks. There were examined 30 welders and a control group of 159 males. In all participants in the study by means of the case history and clinical examination the presence of other pathogenic factors besides the occupational influences was excluded. The percentage part of the males with deviations in the sperm mobility and morphology was significantly higher in the group of welders as compared with the control group (p < 0.001). There were discussed the possible mechanisms which can be responsible for the found changes.
