OBJECTIVES An increasing number of reports suggest that chemical and physical agents in the environment, introduced and spread by human activity, may affect male fertility in humans. This article aims at evaluating the impact of environmental exposures (pesticides, phthalates, PCBs, air pollution, trihalomethanes (THMs), mobile phones) on semen quality, by reviewing most recent published literature. MATERIALS AND METHODS Epidemiological studies focusing on exposure to environmental factors… 


The results from this study suggest that there are many environmental factors which may affect semen quality and sperm count and it is necessary to prevent parental exposure to the agents associated with those hazards.

Outdoor air pollution and sperm quality.

Environmental and lifestyle factors associated with sperm DNA damage

There is uncertainty about the most appropriate laboratory test(s) to identify and quantify such DNA damage and no convincing evidence on possible therapeutic measures.

Exposure to ambient fine particulate matter and semen quality in Taiwan

Exposure to ambient PM2.5 air pollution is associated with a lower level of sperm normal morphology and a higherlevel of sperm concentration, which is in contrast to previous literature on exposure to air pollution and semen quality.

The Relationship Between Widespread Pollution Exposure and Oxidized Products of Nucleic Acids in Seminal Plasma and Urine in Males Attending a Fertility Center

It is highlighted how oxidative stress on the male reproductive tract can be associated with a different representation of metabolic pathways making the reproductive tract itself a target organ for different environmental pollutants.

Air pollution and female fertility: a systematic review of literature

It seems that air pollution could represent a matter of concern for female infertility, according to a systematic review of studies that evaluated the impact of air pollution on female infertility.

Air Pollution and Quality of Sperm: A Meta-Analysis

The results of this meta-analysis showed that air pollution reduces sperm motility, but has no impact on the other sperm parameters of spermogram.

Adherence to reporting guidelines in observational studies concerning exposure to persistent organic pollutants and effects on semen parameters.

SEMQUA proved to be a more specific tool than STROBE for the field of semen quality, and Editors, reviewers and authors should be aware of SEMQUA and apply it when assessing papers on semen quality.

Environment and women's reproductive health.

The current evidence is sufficient to prompt precautionary actions to protect women's reproductive health and a detailed appraisal of compounds specifically related to adverse reproductive outcomes is very important for prevention and risk-communication strategies.



Phthalate Exposure and Human Semen Parameters

There were dose-response relations for mono-butylphthalate and monobenzyl phthalate with one or more semen parameters, and suggestive evidence for monomethyl phhalate with sperm morphology, and the lack of a relation for other phthalates may indicate a difference in spermatotoxicity amongphthalates.

Environmental organochlorines and semen quality: results of a pilot study.

The data showed general trends that were suggestive of an association between PCBs and p,p-DDE and abnormal motility, as well as with sperm concentration and morphology.

The influence of occupational exposure on male reproductive function.

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.

Semen Quality and Exposure to Persistent Organochlorine Pollutants

Adult exposure to persistent organochlorine pollutants within the ranges observed in the present study is not likely to cause reduction in sperm concentration or morphology, however, higher exposure may be associated with impaired sperm motility.

Decreased human semen quality and organochlorine compounds in blood.

Focusing on the subgroup of men with normal semen quality showed that sperm count and sperm progressive motility were inversely related to the concentrations of PCB metabolites within this group, the first time that a correlation between exposure to environmental pollutants with endocrine-disrupting capacity and human sperm quality has been observed.

A Pilot Study Associating Urinary Concentrations of Phthalate Metabolites and Semen Quality

Phthalates are ubiquitous industrial chemicals that are reported to adversely affect human reproductive outcomes. Divergent effects on semen quality have been reported in a limited number of studies.

Correlation of phthalate exposures with semen quality.

Influence of pesticides on male fertility.

An overview of the mechanisms of pesticide-induced reproductive toxicity and the effects on male fertility since exposure to pesticides may be one of the causes of these disorders is provided.

Altered Semen Quality in Relation to Urinary Concentrations of Phthalate Monoester and Oxidative Metabolites

The present study confirms previous results on the relationship of altered semen quality with exposure to MBP at general population levels and includes measurements of di(2-ethylhexyl) phthalate (DEHP) oxidative metabolites.

Contribution of environmental factors to the risk of male infertility.

It is shown that environmental factors contribute to the severity of infertility, and that this may worsen the effects of pre-existing genetic or medical risk factors.
