TL;DR: In utero exposure to PFOA may affect adult human male semen quality and reproductive hormone levels, and Multivariable linear regression analysis suggested that in utero exposed men may have lower adjusted sperm concentration and total sperm count and with higher adjusted levels of luteinizing hormone.

TL;DR: This study suggests that several of the environmental contaminants, belonging to three chemical classes, may be independently associated with impaired fetal growth, and warrants follow-up in other cohorts.

TL;DR: The evidence for an adverse effect on male reproduction of several occupational and environmental exposures and toxicants, such as heat, ionizing radiation, inorganic lead, dibromochloropropane, ethyleneDibromide, some ethylene glycol ethers, carbon disulfide and welding operations, is strongly supported in well-designed epidemiological studies.

TL;DR: High levels of smoking (>10 cigarettes per day) during pregnancy may be a partial explanation for the apparent secular decline and the geographic differences in sperm counts.

TL;DR: There was a consistent association between employment in human service occupations and the risk of affective and stress related disorders and gender was a significant modifying factor with the highest risk levels in men.
