From cbc.ca:

The Disappearing Male is about one of the most important, and least publicized, issues facing the human species: the toxic threat to the male reproductive system.

The last few decades have seen steady and dramatic increases in the incidence of boys and young men suffering from genital deformities, low sperm count, sperm abnormalities and testicular cancer.

At the same time, boys are now far more at risk of suffering from ADHD, autism, Tourette’s syndrome, cerebral palsy, and dyslexia.

The Disappearing Male takes a close and disturbing look at what many doctors and researchers now suspect are responsible for many of these problems: a class of common chemicals that are ubiquitous in our world.

Found in everything from shampoo, sunglasses, meat and dairy products, carpet, cosmetics and baby bottles, they are called “hormone mimicking” or “endocrine disrupting” chemicals and they may be starting to damage the most basic building blocks of human development.

In my recent interview of Drs. Carlos Sonnenschein and Ana Soto, I asked them about Bisphenol A (BPA). Below is the clip from that portion of the interview.

Drs. Sonnenschein and Soto respond to the following prompts:

  1. Describe why you changed your focus to BPA. 00:40
  2. What was the original purpose of BPA? 03:15
  3. Where do humans come into contact with these BPA-laden plastics? 04:30
  4. Do you think the public fully appreciates the magnitude of this problem? 06:35

In their responses, they discuss how they discovered several estrogenic chemicals and why BPA became the primary focus of their research in the 1990s.  They explain the origins of BPA, including the fact that it was originally synthesized to be an estrogen, though it was ultimately used in the synthesis of plastics.  They also describe the ubiquity of BPA in our products — including in plastic water bottles, dispersants in inks, and sealants in teeth.

The full, edited interview is now available on the Upstream Website.
