Air pollution affects sperm quality and increases the risk of infertility in men.

This was discovered in a new medical study .

The study, published in the medical journal JAMA Networks, looked at more than 30,000 men from China.

Research has also shown that the smaller the volume of contaminants in the air, the greater the effects on sperm.

Researchers say that small particles in the air can have more negative effects on reproductive health than large particles.

The results show that men of childbearing age should try to avoid air pollution as much as possible.

Medical experts have long been working on the link between air pollution and sperm quality, but it was not clear how much it increases the risk of infertility in men, but research reports show that 


But it did indicate that air pollution increases the risk of infertility in both men and women.

The study, conducted by Tongji University School of Medicine in China, examined data from 33,786 men in 340 Chinese cities, with an average age of 34 years.

The rates of air pollution in these cities varied and it was observed that between January 2013 and December 2019, the wives of men became pregnant with the help of reproduction technology.

The sperm quality of the men was then tested in particles of different volumes of air pollution.

Although researchers have been able to find a clear link between air pollution and sperm quality (sperm count or quantity), they must know that the smaller the pollutant particles, the more their quality is affected.

According to researchers, small contaminants may travel deeper into the human lungs, causing more adverse effects.

An earlier medical study in China in February 2021 found that air pollution could significantly increase the risk of infertility in both men and women.

The study, analyzing data from 18,000 pairs in China, found that in areas with high particulate matter pollution rates, the risk of infertility increased by up to 20%.

Research has not been able to determine how air pollution can lead to infertility, but it is already known that polluted particles cause inflammation in the body, which can affect the reproductive system of both men and women.

Infertility affects the lives of millions of couples around the world, but little has been done to address the effects of air pollution.

However, it is already known about polluted air that it increases the risk of various aspects such as premature birth and low birth weight problems.

Chen Lee, who was involved in the study from Peking University’s Center for Reproductive Medicine, said couples should be concerned about air pollution.

About 30% of infertile couples do not know the cause of infertility, he said.

“Age, body weight and smoking are common factors for infertility, but our research shows that even small nighttime air pollution increases the risk,” he said.
