Air pollution, traffic noise increase risk of 'infertility' in men and women: study

A groundbreaking medical study has identified the potential causes of the growing infertility in men and women, which are air pollution and traffic noise.

The comprehensive study examined data from 526,000 men and over 377,000 women aged 30-45, who were eager to become parents but faced a high risk of infertility. 

The researchers analysed data on air pollution particles and traffic noise from 1995 to 2017, alongside infertility diagnoses. 

During this period, 16,172 men and 22,672 women were diagnosed with infertility.

The study found that exposure to high levels of air pollution particles for five years increased the risk of infertility in men aged 30-45 by 24 percent. 

However, these particles did not affect women's fertility. 

On the other hand, average traffic noise levels of 10.2 decibels increased the risk of infertility in women over 35 by 14 percent, but not in men.

The researchers said this is an observational study, and further research is needed to confirm the findings.

However, if confirmed, controlling air and noise pollution could be a crucial step in improving male and female fertility rates worldwide.
