Critically Speaking

Nov 3, 2021

Infertility is on the rise, leading otherwise healthy young couples to seek a form of assisted reproductive technology appropriate for their particular situation. This increase infertility of considerable concern. Is one sex affected more than the other? What are the long-range implications if the trend keeps going? Is it only humans that appear to be affected? And the critical question is why? In today’s episode, Therese Markow and Dr. Shanna Swan, author of the new book Count Down, answer many of these questions, including discussion of the types of chemicals and other factors that may contribute to the rising infertility.


 Key Takeaways:

  • The number of “good” sperm observed in human populations (as indicated by the WHO) has dramatically decreased. Other characteristics for function, such as abnormal shape, inability to swim correctly, and chromosomal abnormalities are increasing as well.
  • Male and female infertility is about 50/50.
  • Newborn babies are being born “pre-polluted” with up to 100 environmental chemicals. 
  • One solution you can undertake yourself is to determine where your food comes from, as that’s what’s going into your body.


"I'm convinced that a large proportion of the decline we're seeing is due to chemical exposures, man-made chemicals." —  Dr. Shanna Swan
