The use of natural penis enlargement techniques result in permanent gains in both penile length and thickness.
Once the cells within the erectile tissue have been enlarged and are capable of holding greater volumes of blood, you can expect lasting gains. These cells do not shrink in size once enlarged.
With age, penile shrinkage occurs in all men naturally however. This process begins in middle age although losses in size are not dramatic. At this stage in life the use of natural penis enlargement techniques can also be beneficial in maintaining size.
