BPAs have similar adverse effects on animals as they do on humans. BPAs can cause adverse hormonal effects on animals exposed. In fact, it was because of animal testing that scientists discovered that BPAs may harm humans. Scientists subjected neonatal mice to one injection per day, for 5 days in three doses: 10, 100, or 1000 parts per billion, dissolved in corn oil. Control animals received corn oil alone. At the the age of about 18 months, the mice were dissected and found to have ovarian and reproductive tract abnormalities in the animals treated with BPA.
In laboratory studies, it has been found that BPA can have profound effects that hurt animals. In rodents, there was altered development in the reproductive tract, mammary tissues, the immune system, fat tissue and thyroid. Also increased rates of prostate and mammary cancer was seen. BPA has also been seen to slow the rate of development in tadpoles by interfering with a hormone given out by the thyroid, T3.
Rat studies have demonstrated a connection between health problems and BPA. Animals exposed to chemical experienced increased adult aggression, altered reproductive development in addition to brain development. Researchers from Tufts University displayed a video of mice exposed to low levels of BPA that acted similar to children with ADHD or OCD. I wonder if BPA has anything to do with higher reports these disorders in humans.
