Korean research shows a link between male infertility and noisy bedrooms

Researchers at Seoul National University in South Korea show that male infertility can be related to a long, noisy sleep environment.

The study found that noise levels above 55 dB (according to the World Health Organization's scale) are equivalent to street noise, related to a significant increase in infertility in men.

Previously, high levels of noise were known to be associated with heart disease, mental illness, social behavior changes and interference with complex human activities. Latest research shows the impact of noise on men's infertility.

Jin-Young Min, co-author of the study, said: "Infertility is becoming a significant public health problem because of unexpected negative effects on health and quality of life and heavy costs. We know that noise exposure affects the fertility of males in animals, but our research on this point shows the relationship between exposure to sounds. environmental noise and infertility in humans, namely men. "

To reach this conclusion, the researchers analyzed data from the health insurance database of 206,492 men between 20 and 59 years old and calculated their noise exposure level using the Language Information System. National noise from 2006 to 2013. During the study period, there were about 3,429 cases of diagnosis of infertility in men.

Research shows that the rate of diagnosis of infertility in men is higher in people who are often exposed to noise levels above 55 dB when sleeping at night.

"One of the biggest problems the world is currently facing is environmental pollution, my particular concern is according to what Colborn describes in our book of Positive Future as well. shows that the rapid decline of male sperm in the 20th century is due to environmental pollution of all kinds, if this trend continues, people in the future will not be able to conceive and give birth normally. a man and infertility, you need to consider exposure to polluted environment as a risk factor for which noise is most specific. "

This study has just been published in the Journal of Environmental Pollution in Korea in July.
