In the age of information, the amount of time spent engaging in physical activities is dramatically
less than ever before. More time is spent in environments that require prolonged sitting,
restricted muscle use, and a number of other activities that have limited human movement. As
this sedentary lifestyle becomes more prominent, the rate of obesity in the United States
continues to climb. This increasingly detrimental trend can have a number of adverse of effects
on the body, some of the most prevalent being harmful to the reproductive system.
In a 2007-08 analysis conducted by the National Health and Nutrition Examination Survey
(NHANES), 32.2% of men and 35.5% of women over the age of 20 were said to be obese.
