Washington DC, Aug 6 (THAINDIAN NEWS) New research indicates that concentrations of the chemical Bisphenol A, or BPA, found in the urine of males give them a lower sperm count and sperm quantity.

Results showed the chemical BPA worked like body hormones and may lead to a decline in good health. The chemical is normally used in plastics and cans of beverages and drinks.

The investigation was conducted by John Meeker, who is the Environmental Health Sciences assistant professor at the University Of Michigan School Of Public Health, Russ Hauser, who is a Professor of Reproductive Physiology at the Frederick Lee Hisaw College of Harvard School of Public Health and a group of scientists at Massachusetts General Hospital and the U.S. Centers for Disease Control and Prevention.

The group of scientist also measured the quality, quantity, movement, shape and DNA quality of sperms. They however said further tests needed to be done to conclude these investigations. “We found that if we compare somebody in the top quartile of exposure with the lowest quartile of exposure, sperm concentration was on average about 23 percent lower in men with the highest BPA,” Meeker said.

John Meeker said results indicated people who were hugely exposed to the chemical were about 23 percent lower in sperm quality than the mean not much exposed to the chemical. DNA quality was also 10 percent worse in the men exposed to the chemical.
