Some interesting - if (at first) confusing - reporting by Dr's Oz and Roizen about the fertility health of balls. Upon a first read, you mistakenly think that noise over 55 decibels (dBs) damages The Boys ability to produce healthy swimmers. They report on an Insurance Industry study (but don't specifically cite it) done on 200,000 men who are exposed to 55 dBs on a regular basis, based on place of residency.
Upon a second read, it becomes clear the problem isn't that your balls go deaf -
it's messed-up sleep patterns which are the real culprit.

For noise disturbance, the good doctors recommend:
For stress and anxiety, even Oz and Roizen have prescribed exercise and...a man's favorite stress reducer: Sex. Partnered or alone, it typically takes the mind off other things.

For best results, don't spend time tossing and turning, or grumbling and punching the pillow. Just go right to the solution.
