According to scientists, men’s sperm count is a steady decline over the past 50 years in case of. A study that brought together the results of several studies found that the reason for this global decline was insecticides called insecticides. According to researchers insectists, It can affect people’s hormones and therefore sperm count can decrease.

Lauren Ellis, lead author of the study, said:Understanding how pesticides affect sperm concentration in humans is critical given their abundance in the environment and documented reproductive hazards. Pesticides are a Public health problem.” he said.

The data obtained from previous research were brought together under a common denominator, taking into account the research limitations. Participated in a total of 21 studies and exposed to the two most commonly used groups of insecticides (organophosphates and N-methylcarbamates). 1774 Data from adult men were used. Regardless of the size of the studies, sperm concentration decreased in men in every study. It also stated that the participating men lived in North and South America, Europe and Asia. The process therefore has a global impact on humanity.

The study also showed a decrease in sperm quality. In a 2022 study, the sperm count of non-infertile men in 1973 was 101.2 million, and in 2018 the number was 101.2 million. to 49 million It was said that it was declining. 49 million, World Health Organisation It falls within the “normal” range of sperm density as described by.

There are several factors that influence the number and quality of sperm. Tension, air pollution Such factors reduce the number and quality of sperm in both humans and animals. Researchers say the neurotoxic effects of the active ingredients used in pesticides need to be investigated.
