This is a documentary by BBC Horizon that covers the causes why there is such a decline in male sperm count and an increase of male infertility problems.
What's surprising, even though this documentary was first aired in the early 90's, some of the chemicals that are disrupting the endocrine system causing bad sperms are still in used today... well, at least more people are aware of it, in the case of Bisphenol A.
As mentioned, this documentary was first aired in the early 90's, but the essence of the documentary is timeless. Today, synthetic chemicals are still growing in production and use in the industry including foods and many plastics.
