Bisphenol-A or BPA is a chemical found in hard and transparent plastic items and is used in everything from water bottles to baby bottles. The pressing fact is that, BPA is reported to be a source of several health problems. For instance, it is found to increase the risks of obesity as well as cause brain damage, birth defects and even cancer in humans. The latest results of a Chinese study show that BPA can also cause inferior sperm count and erectile dysfunction problems in men.
For the first time, a research study has related BPA to reproductive issues. According to a De-Kun Li, MD, a reproductive and prenatal epidemiologist at Kaiser Permanente research division Oakland, California, these recent findings related to BPA are not very surprising.
BPA is actually an endocrine disruptor that is capable of blocking male sex hormones such as testosterone. These early findings were based on medical experimentation done on mice and other animals. The results of a more recent study, done on humans, were published in the journal Sterility and Fertility. In this study, urine and semen samples of over 218 samples of factory employees were collected. Few of these men worked at facilities that produced BPA or epoxy resins (that contain BPA).
Results showed that men exposed to BPA are:
- 4 times more likely to have low sperm problems
- 3 times more likely to have lesser live sperm
- 2 times more likely to have a below average motility
- 7 times more likely to have ejaculation problems
- 4 times more likely to have erectile problems
Dr. Li’s team at the research division found similar results during early study, as well. Public health officers and lawyers may soon find enough evidence to seek a ban on this highly controversial substance. Effects of BPA on humans are still controversial but public health officials have managed to wipe it out from certain industrial domains. Canada has already declared BPA as a toxic substance. Canada is the first nation to do so within the entire world. The chemical is yet to be banned in the United States. However, a number of manufactures have volunteered not to use it. Several states have also banned BPA in baby products.
