BPA and fertility
The chemical BPA found in some plastics and epoxy linings of canned food is linked to infertility in men, women--a woman’s ability to become pregnant later in life.
Why protect men, women and children from BPA exposure today? Do it for a healthier tomorrow. BPA is linked to male and female fertility disorders, and early life exposure has been shown to interfere with a woman’s ability to become pregnant later in life. Here's more:
BPA may be more harmful to women with hormone imbalances such as polycystic ovary syndrome. A recent study found higher levels of BPA in women with this common endocrine disorder, suggesting that women with the disorder may be less able to detoxify BPA in their bodies.
BPA may reduce chances of success with in vitro fertilization (IVF). Higher levels of BPA in the body are linked to a 50% reduction in normal fertilization of eggs after they were retrieved for IVF.
High BPA levels are linked to low sperm count. Men with low BPA exposure from environmental sources and high levels of BPA in their urine show decreased semen quality. Gail Prins, a reproductive physiologist at University of Illinois College of Medicine, comments: "Evidence has indicated that for the past few decades, sperm counts have been declining in some human populations — and that this might be related to exposures to endocrine-disrupting chemicals such as BPA is very reasonable."
BPA exposure before birth may cause female infertility during adulthood. A study in the December 2nd, 2010 issue of Environmental Health Perspectives found that fertility fell over time in female mice that had been exposed to BPA during fetal and neonatal development. The doses used in the experiment were lower than or equal to human environmental exposure levels of BPA.
