Global Male Sperm Count Decreases by About 50% Over 50 Years
"Pesticides Negatively Affect Male Reproductive and Fertility Abilities"
Frequent Mobile Phone Use Also Cited as a Cause of Decline
A study has found that the approximately 50% decrease in sperm count among men worldwide over the past 50 years is due to pesticides in food.
According to reports from major foreign media on the 15th (local time), Melissa Perry, dean of the School of Public Health at George Mason University in Fairfax, Virginia, and her research team stated, "There may be multiple factors causing the decline in sperm count, but pesticides such as organophosphates and N-methyl carbamates remaining in the food we eat are strongly associated with the decrease in sperm count."
This research was published on the same day in the journal Environmental Health Perspectives.
Organophosphates are among the most frequently used compounds worldwide and are the main components of nerve gases, herbicides, and pesticides, and are also used in the manufacture of plastics and solvents. Professor Perry said, "People are widely exposed to organophosphates."
Additionally, N-methyl carbamates are used to make pesticides for various field crops, fruits, and vegetables by killing insects through damaging the brain and nervous system.
Regarding this research, Professor Alexander Pastuszak, a professor of surgery and urology at the University of Utah School of Medicine, said, "These pesticides can negatively affect fertility, especially male reproductive capacity."
Frequent Cell Phone Use Also Identified as a Cause of Decreased Sperm Count
Other studies have also pointed to 'frequent cell phone use' as a cause of decreased sperm count.
A study conducted by the University of Geneva and the Swiss Tropical and Public Health Institute from 2005 to 2018 surveyed 2,886 men aged 18 to 22 and found that the high-use experimental group, who used cell phones more than 20 times a day, had a 21% higher likelihood of sperm count problems compared to the low-use group.
Even the group that reported regular cell phone use showed a 30% increased chance of having sperm concentration below the World Health Organization (WHO) standard.
The researchers who published this study explained, "Not keeping cell phones in lower body areas such as front pockets reduces the impact on sperm."
