In some cases, the decrease in circulation to the testicle will cause it to shrink in size. Those who develop the condition gradually will assume that this shrinkage or discomfort is in some way associated with aging.

Any man should be aware that any recurrent or constant discomfort in the genital region is abnormal and they should seek the care of the urologist or primary care physician as soon as possible.
