A new study found that fish like salmon and other fatty foods may be harming your sperm quality
Pesticides in fish and other fatty foods may be harming your sperm quality.
A new study found that men exposed to environmental pollutants through food in their teens may develop defective sperm associated with fertility problems later in life.
Researchers found that high levels of certain pesticides, including PCBs and DDTs, may affect the development and maturation of the testicles, the study said.
“DDT and other pesticides like it continue to linger in our environment and contaminate our food,” Melissa Perry, lead author of the study and the chair of the Environmental and Occupational Health program at George Washington University, told the Daily News.
High levels of PCBs and DDTs may affect the development and maturation of the testicles, the study says
Perry and her colleagues collected and examined blood and semen from about 90 men aged 22 to 40, who lived on Faroe Island — located between Norway and Iceland. For 33 of the participants, they also had blood samples taken at age 14.
The island’s population consumes a seafood-rich diet, that includes pilot whale meat and blubber.
Based on the specimens, the team discovered that men with higher rates of the pollutants in their blood, at age 14, also had increased rates in sperm cells with abnormal chromosomes — a critical factor for infertility in men.
Pesticides like DDT were developed during the 1940s to combat insect-borne diseases
Pesticides like DDT were developed during the 1940s to combat insect-borne diseases like malaria.
They were banned more than 30 years ago in the United States, but still linger in water and soil, and accumulate in certain foods such as red meat, dairy and fish.
As a result, public health experts advice consumers to reduce consumption of fatty fish such as salmon and red meat, which can accumulate pesticides and other pollutants in the fat.
“Most people can reduce their exposure to PCBs and DDT by cutting back on foods that are high in animal fats and choosing fish wisely,” Perry said.
