Fine particulate matter (PM 2.5) is the most studied type of air pollution and refers to dust, dirt, soot, smoke or particles that are smaller than 2.5 micrometers in diameter. These particles of air pollution are so fine they are able to enter your system through your lung tissue and trigger chronic inflammation, which in turn increases your risk of health problems.
A recent study has found exposure to these fine particles may be a factor affecting the quality of men's sperm and fertility.
Air Pollution Linked to Poor Sperm Quality
In this study, researchers evaluated the quality of sperm from nearly 6,500 men ages 15 to 49 between 2001 and 2014. The men willingly participated in a standard medical examination program in Taiwan. The quality of the semen was evaluated based on 1999 standards developed by the World Health Organization (WHO) that included concentration, motility and morphology. The researchers estimated the particle concentration at the participant’s home using a spatiotemporal model and satellite optical depth data. Data was evaluated using three-month and two-year averages of exposure to particulate matter. They found a robust association between altered morphology and level of exposure to PM 2.5 particulate pollution. In fact, with every incremental increase in exposure to particulate matter, sperm morphology degraded by 1.29 percent. This was the largest study evaluating the effect particulate pollution has on semen quality to date. The negative association between air pollution and sperm morphology was found in other studies done in China, the Czech Republic and Poland. The lead author of the featured study commented on the results, saying:
"Particulate matter contains many toxic chemicals such as heavy metals and polycyclic aromatic hydrocarbons, which have demonstrated harm to semen quality in laboratory and animal studies."
These results are concerning as sperm morphology has a critical long-term effect on fertility and on the health of babies born to men whose sperm is affected by pollution. Research has demonstrated the health of a man's sperm is affected by lifestyle choices and consequently has an effect on his child.
