I have read this interesting article, which tells that air pollution can also responsible for the women's fertility.
The connection between a woman’s fertility and air pollution
Risk of infertility was 11% higher in women who lived within a distance of 200 meters from a major highway than those who lived farther.
Women living close to highways are more likely to have fertility issues compared to women who live away from them, suggests a study. The study points out that air around highways is more polluted due to higher movement of cars. Researchers from Boston School of Medicine followed 36,000 women from 1993 to 2003 and examined air pollution and traffic exhaust near their homes to find out if it had any effect on their ability to conceive. About 2,500 women were diagnosed with infertility. It was found that the risk of infertility was 11% higher in women who lived within a distance of 200 meters from a major highway than those who lived farther. The study appeared in the journal Human Reproduction.
