Should Your Guy Avoid Water with Fluoride?

a blog by Kim Griffiths, June 9, 2013

Published in the May 22, 2013 issue of Toxicological and Applied Pharmacology, a new study has discovered that fluoride may be detrimental to male fertility.

Continuous exposure to inorganic fluoride, which is added to 75% of drinking water in the U.S. to promote dental health, can actually result in diminished quality and quantity of sperm cells.

The research team based at Huazhong University of Science and Technology in China administered five mg of fluoride/kg body mass per 24 hours or deionized water to two groups of rats over the course of eight weeks. The fluoride was shown to increase oxidative stress which damages the sperm membrane essential for properly fusing with an egg during fertilization, and also induce testicular inflammation which inhibits healthy sperm production. Overall, rats exhibited decreased number of sperm as well as morphological problems with the sperm.

Fluoride is presumed to promote dental health and tooth strength; however, studies have linked fluoride exposure to bone cancer, diabetes, heart disease, and fertility complications. Further research is required to assess the risk to benefit ratio of fluoride consumption.
