Dioxin Alters Development of Male Reproductive System

DALLAS, Nov. 16 -- A dioxin in the Vietnam War-era herbicide Agent Orange affects the normal growth of the male reproductive system, according to researchers here.
Action Points
Explain to interested patients that the dioxins are know to be carcinogenic, but it has not been clear what effect, if any, they have on the reproductive system.
Note that this study suggests that one dioxin, found in the notorious herbicide Agent Orange, has clear effects on the normal growth and development of the male reproductive system.
Increased exposure to 2,3,7,8-tetrachlorodibenzo-p-dioxin -- or TCDD -- decreases the risk of benign prostatic hyperplasia and lowers testosterone levels, reported Amit Gupta, M.D., of the University of Texas Southwestern Medical Center in the November issue of Environmental Health Perspectives.
"Until now, we did not have very good evidence whether or not dioxins affect the human reproductive system," Dr. Gupta said. "Now we know that there is a link between dioxins and the human prostate."
