Researchers previously knew that air pollution can increase the risk of certain diseases which includes diabetes, obesity and infertility, but they didn't know how it affects the body.
According to a scientists in the University of Maryland School of Medicine, they found out that air pollution affects the sperm count in mice by inducing inflammation in the brain.
Researchers already knew that the stress affects fertility and sperm count in the human body because the brain has the direct link to the reproductive organs.
Zhekang Ying, lead study author and Assistant Profe said, "Our findings showed that the damage due to air pollution - at least to the sperm count - could be remedied by removing a single inflammation marker in the brains of mice, suggesting that we may be able to develop therapies that could prevent or reverse the damaging effects of air pollution on fertility."
This significant study is published in the science journal named Environmental Health Perspectives. The study attempts to trace the root cause of the worldwide fall in sperm count during last few years.
The whole team of researchers, which included Minjie Chen, Xiaoke Wang, and Sufang Chen, Ying, Lianglin Qiu researched that a healthy mice and a mice which is bred without a sign of inflammation in the brain termed it the 'Inhibitor Kappa B Kinase 2' , or in short IKK2 and found the impacts and effects of polluted air on both healthy and IKK2 mutant mice before testing their sperm counts and finally concluding the study.
