The author of the study noted these two damning stats:

•    Men with the highest level of physical activity had a 73 percent higher sperm count than those who had the lowest amount of physical activity
•    Men who watched more than 20 hours of TV a week had a 44 percent lower sperm count

Dr. Jorge Chavarro has a theory behind the sperm production drop-off: He reckons that it’s related to “oxidative stress”- this from various chemical reactions which the body goes through to generate oxygen, and that the oxygen levels generated may damage spermatozoa (and therefore, sperm). Higher physical activity equates to lower oxidative stress, and lower activity to higher stress.
