The number of 'breeds' of men is decreasing
The number of sperm of men tends to decrease and the number of cases of testicular cancer increases in recent years
The number of male sperms tends to decrease and the number of testicular cancer cases has increased in recent years, according to research by scientists in Turku School (Finland).
Scientists conducted research with Finnish men born between 1979 and 1987. These subjects were followed until they were 19 years old.
The results showed that men born in the late 1980s had lower sperm counts than men born in the first years of this decade.
Specifically, the average sperm count of men born between 1979 and 1981 was 227 million, men born between 1982 and 1983 were 202 million and men born in 1987 were 165 million. .
The team also found that men born in the 1980s had a higher risk of testicular cancer than men born in the 1950s.
According to scientists, the cause of men born in recent decades has low sperm count and high risk of testicular cancer is thought to be caused by industrial chemicals that pollute the environment. These toxic chemicals can affect the development of boys.
The BBC news agency quoted Professor Jorma Toppari, who led the study, said: ' Our research shows that the number of male sperm in Finland is decreasing. We are investigating further to find out the exact cause of this phenomenon and how sperm loss affects men 's fertility .'
