Vehicle emissions affect male fertility

A new study suggests that prolonged exposure to vehicle emissions will bring down the quality of sperm, thus affecting male fertility.

Italy Naples University researchers of 85 men were working in the highway toll station research, find their sperm counts and other young men in the same area there is no difference, but the sperm relative weakening, so their fertility are correspondingly reduced.

Male exposure to vehicle emissions environment 6 hours a day, androgen levels in the body does not change, but will decline in sperm mobility, thus affecting the ability of fertilization. About one-third of infertility is caused by abnormal quality of the man\'s sperm count. If less than 20 million sperm number ml, you poor fertility.

In this study, from the expressway toll station of the 85 staff members undergo a complete physical, married 71 of 7 per cent of them were married not procreate. This shows that male long in high concentrations of nitric oxide, sulfur oxide, carbon monoxide and lead, motor vehicle emissions in the environment, carbon monoxide and lead the most easy to damage sperm quality. Researchers call for more in-depth study should be made on this subject, at the same time, health workers also should pay attention to the negative effects of environmental pollution on human health.
