How plastics compound causes infertility

This has been known for a while, but no one will begin to address it on a large scale:

Israeli and American scientists have for the first time uncovered the mechanism by which the chemical compound Bisphenol A, commonly used in the plastics industry, damages human eggs and can harm female fertility.

Studies in recent years have shown a decline in human fertility in both males and females. The new research, which was carried out at Harvard University, and headed by Dr. Ronit Machtinger, a gynecologist at Sheba Medical Center, Tel Hashomer, tried to examine whether human eggs could be damaged by increased exposure to Bisphenol A. The research premise was based on information from previous research on animals that the substances harms various tissues.

Awareness has grown in recent years of the presence of Bisphenol A, especially in the baby bottle industry, in light of concerns that small concentrations of the material could affect babies’ brains and hormonal systems. In December 2010, the Health Ministry instructed hospitals to stop using baby bottles containing Bisphenol A, and in July 2012, the Federal Drug Administration banned further marketing of baby bottles containing the compound in the United States.

However, Bisphenol A is found in many other products, including food storage boxes ‏(marked with the number 7‏), preservative cans, cold drink cans, CD cases, white dental fillings, plastic eyeglass frames and receipts from cash registers. Urine tests in both the United States and Israel show the presence of the material in 90 percent of those checked; concentrations can also be found in blood, breast milk, amniotic fluid and in the fluid that surrounds the eggs in the fallopian tubes.

The present research collected 242 eggs that had been harvested from 121 women undergoing in-vitro fertilization, who had approved use of the eggs for research purposes. Two eggs from each woman were used, one of which was exposed under laboratory conditions to a maturation culture into which varying amounts of Bisphenol A were inserted. The second egg was used as a control, placed in the same culture but without the Bisphenol A. The results showed that after 30 hours of exposure to Bisphenol A, a greater number of eggs did not mature or began to degenerate. Examination of the chromosomes in the egg showed damage that made proper maturation impossible.

Silver Linings Playbook

So many people have told me to see this movie, and last night, I finally did. And yes, I liked it as much as everyone else did. Hard to describe but I can’t think of anyone who wouldn’t like it! It’s also expected to be a Best Picture nominee.
