- BPA Leads to Fertility Defect in Offspring (Natural Society, Oct. 31, 2011):
Bishphenol a (BPA), the headline-topping chemical commonly found in plastics, cans, and food packaging has been tied to yet another negative condition — adversely affecting male genital development and subsequently targeting fertility rates. If you have been following the latest BPA research, then it should be no surprise to you that BPA has been repeatedly linked to diabetes, breast cancer (with over 130 total studies), hyperactivity and depression, and countless other conditions.
BPA alters Anogenital distance, heavily tied to fertility in men
The study, which involved the World Health Organization Collaborating Center for Research in Human Reproduction, examined the effect of BPA on Anogenital distance (AGD). AGD is the distance between the genitalia and the anus, and is biologically very important. AGD has been linked to fertility in males, making the affect of BPA on the male reproductive system quite significant. Linked to both semen volume and sperm count, men with an abnormally short AGD (lower than the median around 52 mm (2 in) have seven times the chance of being sub-fertile as compared to those with a longer AGD.
This is particularly startling due to the fact that BPA has been found in 90% of babies’ cord blood.
Researchers examined 153 boys, 56 with parental occupational exposure during pregnancy and 97 without. After factoring in the weight and age of the boys using regular linear regression, the study found that parental occupational exposure to BPA during pregnancy was associated with shortened AGD in male offspring. What this means is that those who were exposed to high levels of BPA during pregnancy were found to birth offspring with AGD defects. But what about those who do not deal with BPA exposure through their occupation?
