Study: Agent Orange Harms Veterans’ Health

Dioxin, a toxin contained in the herbicide Agent Orange, is harmful to male reproductive health, according to a new U.S. study.

Exposure to the substance limits the growth of the prostate gland and lowers testosterone levels, according to a 20-year study of more than 2,000 Air Force Vietnam War veterans by researchers at the University of Texas Southwestern Medical Center.

U.S. troops and Vietnamese civilians were exposed to dioxins due to the common use of Agent Orange during the Vietnam War.

Lower testosterone levels are associated with decreased sexual function, decreased muscle mass and strength, infertility, increased fatigue, depression and reduced bone density, according to the study appearing in the November issue of the journal Environmental Health Perspectives, although the scientists said more research is needed to conclusively link those health problems with Agent Orange exposure.

Dioxins are among the most toxic substances known and are formed as byproducts of processes such as incineration, smelting, paper and pulp manufacturing and pesticide and herbicide production.

Humans are exposed to these chemicals primarily through consumption of animal fat and dairy products, and once the substance has entered the body it remains there for years or even decades. Babies are often exposed to the highest levels of dioxins through breast milk.
