Scientific research has indicated that air pollution increases the risk of developing certain disorders, ranging from obesity to diabetes.

What’s new in this area came in a study conducted by researchers at the University of Maryland School of Medicine, which showed that air pollution reduced sperm in mice by causing inflammation in the brain.

“Our findings divinely show that the damage caused by air pollution leads to at least a decrease in sperm counts, and it can be treated by removing inflammation in the brains of mice,” said lead researcher Zicang Ying.

He added that it shows that scientists can develop treatments that can reduce this risk or treat it completely.

The new study came as part of scientific efforts to understand the reasons for the decline in sperm numbers in men in recent years.

The study indicated that about 92 percent of the world’s population lives in areas where the level of fine particles in the air with a diameter of less than 2.5 micrometers exceeds the minimum safety standards set by the World Health Organization.

Air pollution can come from vehicle exhaust, factory emissions, forest fires, and more.

During the study, the researchers tested two groups of mice, one of which was exposed to polluted air and the other not to it, and then they examined the sperm of these animals, to find that it was less in those exposed to polluted air, and they also found inflammation in their brains.

This study has implications beyond just fertility, as there are many conditions, such as high blood pressure, diabetes and heart disease, that can result from encephalitis due to air pollution.
