A new study reported by Oxford Journals (www.oxfordjournals.org) and available in a downloadable pdf here, a link has been found between bisphenol-A (BPA) and adverse effects on male sexual dysfunction.
BPA is present in many plastics, epoxy resins and polycarbonates from plastic drinking bottles and baby bottles to some dental sealants. Routine urine tests have found that most people are exposed to some levels of BPA. As quoted from the article “In a national sample of the US population, more than 90% of spot urine samples had detectable BPA with a median urine level of 2.7 mg/l (Calafat et al.,2005; Calafat et al., 2008; National Toxicology Program, 2008). Since BPA has a fast metabolism rate (half-life time ,6 h) (National Toxicology Program, 2008), this finding suggests a continuous exposure to BPA in the US population.”
At increased risk are workers in plants where exposure to BPA might be present.
The adverse sexual dysfunctions identified in men included problems getting or maintaining an erection, orgasmic difficulties, decrease or loss of sexual desire and overall dissatisfaction with sex life.
The article though fairly extensive emphasizes the need for further study.
