Penis – the male reproductive organ is known by many terms like Pecker. Dong. One-eyed Monster, Trouser Snake. Peen. And a question that almost every man has, Is “mine” good sized ?

Does the size of the package determine whether a man can have a satisfying sex life. Is it genetic? What determines the size? This article will answer these questions.

Size

Various studies have tried to determine the penis lengths and circumferences. These studies have suggested that a majority of U.S. men have whats called a “normal” penis size. This “normal” lies around 3.6 inches (flaccid penile length) and 5.2 inches (mean erect length).

Studies also show that more than two-thirds of men are happy with their penis size, and as many as 90% have rated their penile size as average or even large.

So, all things said and done, the answer to the lingering question is, “Well, most erect penises are around 5″ in size.”

Can you Grow your Penis

We are of the opinion that penis stretching exercises can help grow your penis a little: with dedicated regular jelqing exercises,  some men can grow an inch or so in length. The penis is a muscle after all. But these changes are just like bodybuilding; if you stop stretching exercises, you go back to the normal.

Certain surgical techniques can give you a bigger penis, but it has its risks. Unless you are under 3.5 inch erect, it is not something AndrologyForum will even ask you to consider.

Additionally, you can portray the illusion of a bigger dick by shaving off your pubic hair. It actually does make an impact, so if you have a bush, shave it off and see for yourself 🙂

Height and Weight Correlation

Another popular belief with penile size is related to height and weight. Various researchers have also tried to determine a person’s height to penile length ratio, but have not been able to come with any scientific study that shows a connection.

So, the answer to the question height and weight is involved in penile size is a resounding NO.

Race Factor

Although there are some anecdotal accounts of Africans and black people having bigger penis than Whites and Asians, there are actually not many controlled and detailed scientific studies to scientifically prove that a particular race is better endowed down there in general.

Below is a popular chart first published on targetmap.copm depicting the size prevalence across different countries/races.

The above chart did not clarify about the veracity of the data used. We do not think the depiction is credible.

Our opinion is that there are more bigger penises among Africans than the rest of the world and that South Asia has more smaller penises than the rest of the world. Nevertheless the average penis overall does not vary much. Hope this makes sense.

Genetics Influence

Whether a fetus will grow to be a male or a female depends on chromosomes. Reproductive organs start developing after the seventh week, and the Y chromosome is responsible for the production of testes and other male reproductive organs.

However, the Y chromosome does not solely determine the size of your penis. There are other factors also at play, like your unique individual genes and the X chromosome that boys inherit from the mother.

You could inherit genes for a bigger penis from one of the chromosomes of your parents, but in the end it could be a combination of your individual novo genes mutation (that’s unique to you) that could eventually make you big or small down there.

Hormonal Response

The knowledge that we have regarding the factors that influence the size of the penis is minimal. While genetic do play a role, the extent is unclear. Along with genetics, what influences the size as well as shape is the hormonal responsiveness during a man’s early childhood as well as puberty.

During puberty, growth hormones, along with testosterone, also come into play. Hormonal exposure to environmental estrogens (female sex hormone) during puberty are widely believed to have the potential to inhibit penis size.

Endocrine disruptors found in plastics, detergents and pesticides can also cause a negative influence on the penis during puberty.

Nutrition

Malnutrition during puberty and even earlier while in the womb can affect the penis size and overall growth.

Grower or Show-er?

Studies involving penile physics have shown that there indeed exist “growers” and “show-ers” amongst us. Studies have reported an increase of an average of 42% in penile length (flaccid to erect state) and in growers this percentage increase is even more pronounced.  Long story short, often, growers have a higher ration of ‘erect to flacid length’ ratio compared to “show-ers”.

Yes, it’s true. While not always, it is indeed true that some men having shorter flaccid penis can have a dramatic growth when compared to certain individuals with larger flaccid penis. This only means one thing – some people grow and fill-up better than others and appearances in the locker room can be deceptive.

Skills Matter

Very often, we wonder, does the baseball bat size influence the number of home run a player makes? It does, but it is not the only influencing factor. The skill of the batter also comes into play here.

If we juxtapose the same question in human sex life, then the answer might surprise you. Women, creators of a majority of penile myths, do not commonly have a fixed criteria. Good penile size is good, but it is not the only alluring factor, and not more important than features such as height and shoulder-to-hip ratios.

Anecdotal statistics have also revealed that only when the penile length got as low as 3 inches, did the penis size become decidedly unattractive.

This only shows most of the myths regarding the penis is well…myths. In fact, more than 85% of the women were completely okay with the average 5″ penis size. For many, skills matter and not the size.

Conclusion

Remember, when it comes to what’s present in the pants, as long as it is healthy, size is not the most important factor.
