High BPA levels affect male fertility by hurting sperm quality


You might have heard about BPA or Bisphenol A compound and side effects associated with it. BPA has been in use for several decades and now is used mostly in polycarbonate plastic. It can be found in sunglasses, CD’s, paper coatings and the fillings in your teeth. It is also used to coat the inside of tin cans and make plastic shatterproof. According to a recent report released by the Environmental Protection Agency, release of the BPA to the environment exceeds 1 million pounds per year. A recent human study published in Fertility and Sterility showed the effect of BPA levels on sperm quality in men, which could affect their ability to conceive a child.  




About the study
The study was conducted on 218 Chinese workers for five years. Researchers tested urine and measured semen quality by examining factors like concentration, vitality, motility (movement), total sperm count and morphology (size and shape). The results showed that

The study author De-Kun Li, MD, PhD, a reproductive and perinatal epidemiologist at Kaiser Permanente’s Division of Research in Oakland said “The higher the BPA exposure, the worse the semen quality.”

Researchers told that exposure to BPA levels varied among the men, but occupational exposure to BPA was the most significant contribution to higher levels of BPA.

Besides affecting sperms quality in men, exposure to BPA can cause various other harmful effects including Breast cancer, Testicular cancer, Diabetes, Hyperactivity, Obesity, Miscarriages and other reproductive failures.
