Testosterone and Penis Size

Test and Penis Size

Men use testosterone for many different reasons throughout their lives. Some, such as athletes and bodybuilders, use it for performance enhancement.

Others take it to replace the testosterone their bodies no longer make naturally. In either case, men often have questions regarding testosterone and penis size.

Natural Growth during Puberty

As you might already know, testosterone is the hormone responsible for triggering pubescent changes in men.

It gives men their masculine characteristics and results in the growth of body hair, a deepening of the voice, and, of course, penis growth. Penis size increases dramatically between the ages of 12 and 18, and by age 21, the size of the penis is set in stone.

Although some people claim that there are supplements (like testosterone) or even HGH (Human Growth Hormone) that can influence the size of the penis during these crucial years, this is not the case. Genetics determines your penis size and nothing else.

Bodybuilders, Exogenous Testosterone, and Penis Size

A common question among those who are curious about anabolic steroid and exogenous testosterone use is whether these compounds can actually increase penis size. In fact, a few different studies on testosterone supplementation have actually focused on penis growth.

Although some growth did occur on average among men who utilized testosterone supplements for performance enhancement, it only totaled about a centimeter, or a third of an inch. It is also important to note that any compound which causes the penis to grow would also affect the testicles and the prostate, which can be dangerous.

Anabolic steroids can also have an effect on the size of the penis, especially after the completion of a cycle. Steroids suppress natural testosterone production, and it can take some time for this production to return to normal once the cycle ends.

Post-cycle therapy with a SERM can certainly help, as can using anabolic steroids responsible. Many men find that incorporating hCG into their cycles and post-cycle therapy allows them to negate any side effects associated with lack of testosterone, too. The following chart shows recommended hCG doses on-cycle and post-cycle.

During Cycle
500IU Twice Weekly
Entire Length of Cycle
Post Cycle
1000IU Every Other Day
2 to 3 Weeks

Remember that hCG should be added to your standard PCT with drugs like Clomid or Nolvadex; it does not serve the same purpose as these drugs and cannot take their place.

Lack of Testosterone and the Shrinking Penis

Many, many men report that they experience penis shrinkage as they age. Much like an abundance of free testosterone can cause insignificant growth, a lack thereof can cause insignificant shrinkage. Studies show that men may lose an average of half an inch over their lifetimes as they age and testosterone production wanes.

Although some men report a much greater loss of size, this is often due to the development of abdominal fat and fat in the pubic area which only makes the shaft of the penis appear shorter. As these men lose weight, their penis size returns to normal.

The Real Reason for Increased Penis Size

On the flip side, many bodybuilders and athletes report an increase in penis size as it refers to the girth, or circumference, of the shaft. While a lot of these individuals tend to thank the testosterone or the steroid, believing that the same compound that causes muscle growth must also make their penises grow, this is not the case.

The penis becomes erect when the vessels inside become engorged with blood. Since anabolic steroids and testosterone increase blood volume to a degree, the penis’s girth may increase slightly during that time simply because there is more blood inside of those vessels.

Testosterone’s Effect on Sexual Performance

Testosterone and Penis SizeWhile it’s true that testosterone and penis size are linked, and that changes in the amount of hormones in your body can influence your penis size just slightly, testosterone seems to play a much larger role when it comes to sexual performance.

Men dealing with low testosterone often struggle to achieve erections, and those who do sometimes have trouble maintaining their erections.

Men with low testosterone also experience a lack of sexual desire, which explains why older men are not as interested in sex.

Introducing exogenous testosterone into the body can have a tremendous impact on your sex life, especially if you have low levels to begin with. In fact, this is one of the primary reasons why men seek medical treatment for low testosterone, and low testosterone is one of the main causes of erectile dysfunction, too.

This just goes to show the importance that testosterone plays in your sex life, even though testosterone has only a slight impact on your penis size.

Testosterone’s Relation to Erection Quality

Testosterone and penis size share a small link in men who are otherwise healthy. This simply means that men who have ample testosterone in their bodies will see very little (if any) change in penis size if they introduce exogenous hormones.

However, men who have low testosterone may notice a change in the overall quality of their erections when using the hormone, and this becomes even more noticeable once the hormone levels have stabilized in their bodies.

With this information in mind, even though testosterone and penis size do not share a tremendous link during a man’s adult years, introducing testosterone certainly can make a man’s penis feel larger and harder to his partner.

This is true even though measurable growth is minimal. For this reason alone, women often report a noticeable difference in their sexual pleasure following their partners’ regular use of testosterone supplements.

Testosterone and Sexual Stamina

Finally, in exploring the links between testosterone and penis size, many people agree that a healthy sexual relationship isn’t as dependent on penis size as it is sexual stamina. A 2008 Canadian survey of sex therapists and doctors confirmed that intercourse should last anywhere from seven to 13 minutes to be fulfilling for both partners.

For comparative purposes, the average intercourse session lasts anywhere from three to seven minutes, and therapists agree that it is very rare for the act of intercourse itself to last longer than 12 minutes.

Test and Penis SizeAnother interesting fact to consider is the time it takes each sex to achieve orgasm through penetrative sex. Men often climax in roughly seven to 12 minutes; women, on the other hand, may need up to 20 minutes.

It only makes sense that men should focus less on the effects of testosterone and penis size and more on the effects of the hormone on their stamina.

Just as testosterone can allow men to work out more intensely for longer periods, the same can be said for sex. This is yet another reason why men and women alike report having better sex lives when men use testosterone supplements.

To answer the pressing questions, your penis may grow during exogenous testosterone use, and it may shrink if there is not enough testosterone in your body. However, in both cases, the growth or shrinkage is so insignificant that you – and your partner – will never notice the difference.
