“…Semen quality analysis, the standard clinical approach to assess male reproductive capacity, can be considered a sensitive biological marker of exposure to toxicants at the workplace [5]. Based on semen quality analysis, it has been stressed that the percentage of men whose sperm count has fallen below the level associated with optimal fertility has increased [6][7][8].…”

Objectives: This study examined the association between male infertility and certain occupational exposures. Material and Methods: A case-control study was carried out from January 2008 to February 2009; on 255 infertile men and 267 fertile men controls. Occupational exposure to certain chemical, physical and psychological workplace hazards was assessed by self-report questionnaire. General and andrological examination was conducted for all participants, however, semen analysis was done only for the infertile men cases, because the fertile men controls refused to give semen samples. Results: After adjustment of confounders, the results revealed that the following workplace exposure factors significantly increased the risk of male infertility: solvents and painting materials (OR: 3.88, 95% CI: 1.50-10.03), lead (OR: 5.43, 95% CI: 1.28-23.13), VDTs and computers (OR: 8.01, 95% CI: 4.03-15.87), shift work (OR: 3.60, 95% CI: 1.12-11.57) and work-related stress (fairly present: OR: 3.11, 95% CI: 1.85-5.24; often present: OR: 3.76, 95% CI: 1.96-7.52). Conclusion: In spite of the limitations of this study, it supports other studies that raise the attention to minimize the exposure to the workplace hazards that may affect the fertility of male workers.

“…Occupational activities involving exposure to specific chemicals or expositions to toxicants may impair male reproductive health and cause infertility in humans [27,37,[42][43][44][45][46][47][48][49][50][51][52][53][54][55][56][57][58].…”

Only few studies have explored differences between infertile males attending fertility clinics and controls [27,45,50,[59][60][61] and findings are inconclusive. While some studies found differences between fertile and infertile males in their occupational activities (such as, welding, being a white collar professional or exposure to metals), their exposure to chemicals (like solvents) or to physical agents (like electromagnetic fields or heat), other studies did not find significant differences to the same or similar exposures.…”

Human semen quality may be declining due to environmental pollutants, occupational exposures or changes in lifestyle. Nonetheless, we still know little about the impact of those factors on male fertility. Some heavy metals, volatile organic compounds or xenoestrogens may compromise reproductive male function. This process could take place along the human life cycle and not only in certain stages of development. We review the main factors that affect human male fertility and their possible influence in current human reproduction.

“…Pesticides [43][44] , several heavy metals like lead or cadmium [45][46][47] and several air pollutants (PAHs, dioxins) [48,49] have been shown to compromise the reproductive male function. Several studies have explored and compared men's semen parameters and occupational exposures in male partners of infertile couples attending infertility clinics [46, 50,54-JMSCR Vol||05||Issue||07||Page 24325-24333||July 2017 56] .…”
