If you want to keep your sperm strong, toss that plastic water bottle. Research published in the February 2010 issue of Environmental Science and Technology found exposure to BPA — an organic compound used in the manufacture of plastic — could affect thyroid and reproductive hormone levels in men.

The study measured urinary concentrations of BPA and compared them to levels of serum thyroid and reproductive hormone levels in 167 men from an infertility clinic. Eighty-nine percent of the urine samples had detectable levels of BPA in them. Men with a higher concentration of BPA in their urine had higher blood levels of follicle-stimulating hormone and lower levels of inhibin B, both of which are associated with poor sperm quality.

While this is only a preliminary study, it adds to a growing body of research that finds BPA exposure increasing the risk of male infertility. Do you really want to take a chance with your swimmers?
