A new sci-fi movie may be anticipating the real world.  The plot of the movie involves humans becoming infertile.  This month’s British Medical Journal published the following startling findings along the same line;

“Evidence exists of a decline in semen quality over recent decades and a deterioration in the reproductive health of males, with an increase in the incidence of testicular cancer and probably of hypospadias and cryptorchidism–the “testicular dysgenesis syndrome”. One cause that has been suggested is endocrine disruption due to environmental agents with oestrogenic or antiandrogenic effects, although direct evidence is lacking and other mechanisms are possible.”

“In parallel, during the same period the proportion of male offspring (commonly called the secondary sex ratio) has been declining in many countries, including the United States and Canada and several European countries.”

The authors go on to state that 2 known environmental pollutants, dioxin and bisphenyl-A, are known to disrupt the endocrine system and impair fertility.  They did not discuss another important factor—pesticides and herbicides.  Read more about pesticides and herbicides and male fertility here.
