Warning All Men

Something is going on with sperm counts if a recent study of French men is reflective of men in other parts of the world.  And some studies in other countries have also shown declining sperm counts. At the same time, the incidence of testicular cancer has increased, doubling in the past thirty years.  No one knows why these things are happening, although the environment is a strong contender.   Suprisingly, some think tight underwear may be the cause as the testicles need to be below body temperature to make healthy sperm.
