“…Another example is that of welders, who are exposed to heat, solvents, heavy metals and noise. As previously stated 17,18) , theories exist about the diminished sperm quality in welders, but the weight of each associated factor in the impairment has not yet been established. As such, there are many methodological problems in these studies.…”

“…In human studies, it has been found that exposure to chromium is significant in welders. Diminished sperm quality among welders has been demonstrated in a number of studies 17,18) , but has not been definitively linked to exposure to chromium. As such, this profession is linked generally with occupational exposures affecting fertility (see details which follow).…”

Effect of Occupational Exposures on Male Fertility: Literature Review

et al. 2003

The present review was aimed to determine the influence of working conditions, occupational exposures to potential chemical and physical reproductive toxic agents and psychological stress during work on male fertility. Significant associations were reported between impaired semen parameters and the following chemical exposures: metals (lead, mercury), pesticides (dibromochlorophane, 2,4-dichlorophenoxyacetic acid), ethylene glycol ethers and estrogens. The following physical exposures were shown to deteriorate sperm parameters: radiation (both ionized and microwaves) and heat. Psychological distress has another important contribution to infertility. Several studies indicated that stress has a negative impact on sperm parameters. Occupational parameters should be an important part of history taking among patients attending infertility clinics.

“…Two reproductive studies reported that the morphology and concentration of sperm was poorer in welders than in controls [13,14]. However, another study failed to find any difference in the semen parameters between steel welders and controls [23]. This study has shown that liquefaction time has significantly longer in leather tanning workers; some studies have shown prolonged time among welders, while other studies have shown longer times among controls [13,22].…”

Objectives: To examine the difference in semen qualities of male workers in leather tanning factories and of those in other industries. Methods: Eighty reproductive aged male workers from six leather tanning factories and eighty-five from non-tanning workplaces participated in the study as the exposed subjects and non-exposed subjects, respectively. Each subject was given a physical examination, required to complete a questionnaire, and asked to supply a semen specimen. Semen analysis on fresh specimens followed the latest World Health Organization guideline. Semen parameters were compared between the exposed and non-exposed subjects using tabulation and chi-square test for categorical variables and t-test or rank-sum test for continuous variables. Multiple linear or logistic regression models were constructed to examine the independent effects of exposure. Results: After adjusting for confounding variables, exposed subjects had significantly higher percentages of grade C motility (p=0.008), mid-piece defect (p=0.009), and tail-defect (p=0.029) in their spermatozoa compared to non-exposed subjects. Liquefaction time was also longer (p=0.046). Conclusion: Leather tanning workers have significantly higher percentages of grade C motility, mid-piece defect, and tail-defect in their spermatozoa.

“…However, in earlier studies, whenever a distinction was made between mild steel and stainless steel welding, the most substantial effects were found among mild steel welders (2,3). A cross-sectional study of stainless steel welders did not reveal a reduction in semen quality, even among those who used the manual metal arc method and were thought to be the most exposed (4).…”

“…Semen quality was observed to decrease with increasing exposure to welding fumes. Preliminary results of a study of stainless steel welders did not, however, indicate reduced semen quality (4). Two studies with different methodological approaches have reported associations between paternal welding exposure and delayed conception (2,5).…”
