The fertility of thousands, even millions of men, may be impaired without them realizing it. This has to do with the environment in which they live.
The fertility of thousands, even millions of men, may be impaired without them realizing it. This has to do with the environment in which they live.
In a study published in the journal JAMA Network Open on February 18, a team of experts in China found that the sperm of men living in heavily polluted areas had less mobility.
Motility is how sperm swim. The stronger the sperm, the easier it is for them to swim forward in search of an egg. This is also considered a measure of their health.
According to Medical Express, the authors used sperm samples sent to fertility clinics in the past few years. These samples were collected from nearly 34,000 men living in 130 locations in China.
The authors divided volunteers into four groups based on the level of air pollution in the area where they lived. These men are then examined by fertility specialists for sperm quality. They focused on sperm count, concentration and motility.
The results showed that there was not any link between the quantity produced and the concentration of sperm and the level of air pollution. However, the most special thing is the connection between sperm motility and this factor.
People who live in areas with high concentrations of particulate matter and high pollution have very low sperm health. Particulate Matter (PM) is microscopic airborne pollutant particles, just a mixture of solid particles and liquid droplets found in the air.
In particular, in those exposed to particulate matter smaller than 2.5 micrometers, their sperm health decreased by 3.6% compared with the average for Chinese men. Similarly, for those exposed to particulate matter 10 micrometers in size, their sperm health decreased by 2.44%.
