"A study of men from the Faroe Islands finds that high DDT and PCB exposure during adolescence and adulthood is associated with abnormal chromosomes in sperm".

"Men exposed to certain banned but long-lived chemicals at high levels as teenagers are more likely to have defective sperm later in life, according a new study.

Researchers report today that organochlorine chemicals—specifically DDT and polychlorinated biphenyls (PCBs)—may affect how testicles mature and function. It is the first study to examine men’s exposure to the chemicals during the teenage years and abnormal sperm later in life, and suggests that the chemicals—banned in the United States but still lingering in soil, water and people—may contribute to male infertility.

“These chemicals continue to persist in our environment. Levels are going down over the past 30 years, but all of us still have levels in our bodies,” said lead author Melissa Perry, a professor and researcher at George Washington University’s Milken Institute School of Public Health."
