It’s commonly known that male libido levels will decrease with age. However, the focus of this article is on a more unknown age relatedmale sexual health problem*. Recent studies have confirmed that penis sizedoes indeed decreasethroughout the aging process. In addition to impotence, men will also experience the continual shrinkage of their penis. This fact can cause much alarm in men as sexual vigor is an essential component for maintaining a high quality of life. How much does aging actually affect penis size?

VisibleSigns of an Aging Penis

1) Appearance

There are two significant changes in penis appearance correlated to aging. The glans (head of penis) will slowly lose its purplish appearance and is the result of reduced blood flow. Secondly, there is a significant loss of pubic hair. Irwin Goldstein, MD, editor-in-chief of The Journal of Sexual Medicine has written about this change. “As testosterone wanes, the penis gradually reverts to its prepubertal, mostly hairless, state.”The short description is that aging will slowly erase the sexual abilities of youth and physically returns the body to its original state before puberty.

2) Permanent Decrease in Penis Size

The penis undergoes an actual decrease in size during the aging process. This reduction affects not only penis length but also thickness. The positive news is that the average man will only experience a size decrease of 1-2 inches. Goldstein states, “If a man’s erect penis is 6 inches long when he is in his 30s, it might be 5 or maybe 5-and-a-half inches when he reaches his 60s.”Decreased penis size is caused by two separate factors. Foremost, is the slowed deposit of essential fatty substances within the small arteries of the penis which results in poor blood flow. The second cause isdue to buildup of relatively inelastic collagen (scar tissues) within the stretchy fibrous sheath that surrounds the erection chambers. These chambers must fill up with blood in order to achieve an erection. Blockages in the penile arteries and inelastic chambers result in smaller erections.

3) Decreased Size of Testicles

Testicles began to shrivel around the age of 40 in most men. The average size decrease experienced in testicle size is around an inch. Goldstein explains, “the testicles of a 30-year-old man might measure 3 centimeters in diameter, while those of a 60-year-old, perhaps measures only 2 centimeters.”


Decreased ability to perform sexually is a difficult topic yet one that inevitably needs to be addressed. Every man will experience reduced penis size among numerous other sexual performance issues during the aging process. Goldman clearly describes this issue “”The most important ingredient for a satisfying sex life is the ability to satisfy your partner. And that doesn’t require peak sexual performance or a big penis…” Discussing and investigating this issue is important as solutions exist to help reduce the severity of age related sexual difficulties. A healthy diet and daily exercise are both shown to decrease the effects of aging. The other solution involves the use of sexual health supplements for men*. Products such as Formula 41 and Zytenz are suggested to effectively combat the size loss associated with aging. Natural supplements do not provide a magic cure or add 4 inches to penis length. Yet, these supplements do contain ingredients proven to increase overall health by providing additional sources of fatty acids and essential nutrients.
