How Well Do You Know Your Penis Trivia?

It would be a lie of epic proportions to say any man goes even one day without thinking, in one way or another, about his penis. 

In fact, across all cultures and from a very early age, a man’s penis plays a central role in his life. 

This is not just because of the functions it performs, but also because of what it represents. 

However, no matter how well we might think we know our penises, there remain a number of penile facts that are sure to surprise the majority of readers. 

In this article, we’ll share some of the most useful penis trivia, along with several entertaining penis facts we found from medical sources and recent research. 

Not only will these facts help you better understand your penis, but they might also help you appreciate it more. 

1. Penises Can Actually Be Broken


Of course, we all know that there’s no “bone” in a boner.

Your penis is merely a collection of capillaries that expand when they fill with blood, causing an erection. 

So how could this painful-sounding fact possibly be true? 

You see, while not a “break” in the traditional sense, it is possible to suffer something known as a penile fracture. 

This is what happens when you cause enough trauma to your penis to damage the fibrous tissues holding it together. 

This is usually accompanied by extreme pain and a popping or “cracking” sensation. 

Luckily, penile fractures can only take place when you are semi or fully erect. They are also quite rare and usually happen during particularly vigorous intercourse. 

The bad news is that they require treatment from a doctor, and will take quite some time to heal. 

2. The “Shoe Size” Myth is Just an Urban Legend

penis trivia

When it comes to making assumptions about male penis size, the most commonly-cited method is the “shoe test.” 

In fact, many people (both male and female) swear up and down that there is a direct link between a man’s penis size and the size of his footwear. 

And since most men with large shoe sizes tend to be tall, our concept of proportion just seems to tie the whole rumor together. 

Unfortunately for the basketball players out there, a number of major studies (both recent and classic) have repeatedly concluded that there is no correlation between the size of a man’s penis and his feet. 

Curiously enough, however, penis size has been shown to correlate with factors like age, height, and the length of the male index finger.

3. Morning Wood and Wet Dreams Are Common (and Natural)


No doubt, most men have some memories of a time in their life when their penis seemed more like an enemy than a friend. 

This was most likely adolescence, when hormone shifts caused frequent unwanted (and usually uncontrollable) erections. 

Of course, many of us still have “flashbacks” to this time in our life when we wake up in the morning. 

However, “Morning Wood,” as it’s called, is not only common in men of all ages, it’s perfectly natural. 

You see, when you sleep, your brain starts to relax, which causes a lot of hormonal changes in your body. 

In particular, you testosterone levels begin to elevate, and your body stops secreting chemicals that keep day-time erections at bay. 

In fact, your testosterone levels are highest when you first wake up, which is a big reason for that morning flag pole. 

Of course, sometimes your penis’s nighttime activities will go even further, resulting in what we typically call a “wet dream” or a “nocturnal emission.” 

Though these are widely associated with puberty, they can happen at any point in our adult life. 

And while it’s common to assume you had a particularly tantalizing dream the night before, it’s just as likely that you moved your body or laid is such a way as to stimulate yourself to orgasm. 

In fact, if you sleep on your stomach, you’re much more likely to have this happen.  

4. Size-Wise, the “Big Guys” are a Major Minority

penis trivia

Size myths and the pervasiveness of pornography have caused many modern men to become insecure about what they’re packing. 

No doubt, you’ve heard stories from female friends about encountering barely-manageable penises, or seen videos of surreally-sized men peppered all over the internet. 

However, the first thing to note here is that size is relative and what is big to one person might not be to another. 

As for those porn stars, keep in mind that many of those men are specifically hired due to their size. 

At the same time, the average height of their female co-stars (hint: it’s only 5’5) and specific camera angles help make them look even more impressive. 

Moreover, these guys represent a tiny portion of the population boasting more than 7 inches. 

The truth is, research indicates that the average penis is and always has been around 6 inches.

5. Your Ejaculate is Lightning Quick 

File this one away in the party trivia section of your mind, as it’s sure to fascinate everyone you know. 

The speed at which sperm leaves your penis when you ejaculate has been measured at 28 miles per hour (or 45 kph). 

Finally, something we can all be proud of!  

6. Manscaping is a “Growing” Trend

Trimming up one’s privates has long been a preference for women all around the world.

Men, however, have only recently started taking the time to really care about their pubic hair. 

Still, the trend is growing, with over 50% of guys taking a trimmer to their naughty bits on a weekly basis. 

Many men who are reluctant to reign in their pubic hair blame porn, for the growing popularity of this practice. 

However, it might just be a sign of the times (or a sign that a neater, well-maintained groin area results in better reactions from the ladies). 

7. Your Penis Can Do a Few Tricks

By the time you reach adulthood, it’s likely you’re aware of pretty much everything that your penis can (and can’t) do.

 In fact, there are actually penis acrobats out there to make a living performing specific tricks with their members.

Providing you’re open-minded and up for an NSFW viewing, you might consider taking a look. 

Perhaps the most impressive “trick” that you can apply to your penis is the use of your Kegel muscles. 

These are absolutely crucial to avoiding premature ejaculation and to developing more control over your big moment. 

If you’re wondering how to access them, try cutting off your urine stream the next time you visit the bathroom. 

That’s exactly the sensation you want to recreate when building up your Kegel muscles. 

 8. There’s No Rules Regarding Erections

penis facts

As we mentioned when discussing “morning wood,” there are countless reasons why your body might produce an erection. 

Of course, the first and most obvious is that you are sexually stimulated in some way (either physically or mentally). 

However, your body doesn’t need to be exposed to any stimuli to send blood rushing into your penis. 

While this can be cause for embarrassment in some situations, you can develop some mental control over when and where you get hard – but it takes some practice. 

While we’re on the topic, it’s worth noting that you experienced at least one erection before you were born, and will also experience one shortly after you die. 

9. Penis Trivia – Two Penises?

Though it is very, very rare, it is actually possible to be born with a condition called diphallia, a fancy word for having two penises. 

Though it only affects about one in 5 million men, videos of men with this condition have cropped up in some of the internet’s seedier websites. 

However, before you assume that this is some sort of benefit, it’s worth noting that (in most cases) one or both of the resulting penises are highly deformed and potentially non-functional. 

10: Penis Trivia – Fertility and Penis Size

The relationship between penis size and fertility has been a subject of scientific inquiry for many years.

While there is no conclusive evidence to suggest that penis size is directly linked to fertility, there are some studies that suggest a possible correlation between the two.

One study published in the journal Fertility and Sterility in 2015 found that men with smaller penises had a higher risk of infertility compared to those with larger penises.

The study analyzed over 800 men and found that those with a penis length of less than 4 centimeters when erect had a higher risk of infertility than those with a penis length of over 12 centimeters.

Another study published in the International Journal of Impotence Research in 2009 found that men with larger penis size tended to have higher semen volume and sperm count than men with smaller penis size (source).

11: Penis Size and Masculinity

The size of the penis has long been associated with masculinity in various cultures around the world.

In many societies, a large penis is seen as a symbol of virility, strength, and sexual prowess, while a small penis is often seen as a sign of weakness, inadequacy, and lack of manliness.

In some cultures, a large penis is considered essential for a man’s status and self-esteem. For example, in ancient Greek and Roman cultures, a large penis was a sign of a man’s physical and moral strength.

Similarly, in many African and Middle Eastern cultures, a large penis is associated with fertility, potency, and masculinity.

However, in some cultures, the size of the penis is not as important. For instance, in Japanese culture, the emphasis is more on sexual technique and skill rather than the size of the penis.

In China, a small penis is considered a sign of humility and modesty.

12: Penis Trivia – Origin of the Word Erection

The word “erection” has its origin in Latin, from the word “erectus,” which means “upright” or “elevated.” The word has been used to describe the state of the penis since the 1590s, according to the Oxford English Dictionary.

The Latin word “erectus” is the past participle of “erigere,” which means “to raise up” or “to erect.” This word is composed of two parts: “e-” meaning “out” or “up,” and “regere” meaning “to direct” or “to control.” So “erigere” literally means “to direct or control upward.”

The word “erectus” has been used in various contexts throughout history, including in architecture to describe buildings with tall and vertical structures.

It wasn’t until the late 16th century that the word started to be used to describe the state of the penis when it is engorged with blood and erect.

Overall, the origin of the word “erection” reflects the Latin roots of the English language and highlights the importance of the penis in human biology and sexual health.

13: Penis Trivia – Things Can Go Wrong

The penis can be affected by a variety of medical conditions, including Peyronie’s disease, which causes the penis to curve or bend during an erection. 

Other conditions that can affect the penis include priapism (a prolonged and painful erection), phimosis (a tight foreskin that cannot be retracted), and balanitis (inflammation of the glans).

14: Penises Can be Strange in the Animal Kingdom

  1. Walrus: Male walruses have a penis bone, also known as a baculum, that can grow up to 30 inches in length. The baculum helps the male walrus maintain an erection for an extended period, which is necessary for successful mating.
  2. Elephant: The penis of an elephant is the largest of all land animals, with a length of up to 6 feet. It is also prehensile, meaning it can move and grab objects, which helps during mating.
  3. Whale: The blue whale has the largest penis of any animal, measuring up to 8 feet in length. It is also one of the fastest-growing organs in the animal kingdom, growing up to 3 inches per day during the mating season.
  4. Duck: Male ducks have a unique, corkscrew-shaped penis that can extend up to 17 inches in length. This adaptation helps them mate with female ducks, who have complex genitalia that can make it difficult for males to fertilize their eggs.
  5. Snake: Snakes have a pair of penises, called hemipenes, which they use to fertilize the female. Some species of snakes also have spines on their hemipenes, which help them grip onto the female’s reproductive tract during mating.
  6. Koala: The penis of a male koala is bifurcated, or split in two, with each half used independently during mating. This adaptation may help them mate more successfully with female koalas, who have two uteri.
  7. Gorilla: The penis of a gorilla is relatively small, measuring around 1.5 inches in length. However, the testicles of a gorilla are much larger than those of humans, producing more sperm for successful reproduction.

15: Penis Trivia – The Worlds Smallest Recorded Penis

The world’s smallest recorded penis belongs to an anonymous man who was measured in 2015 as having a fully erect penis length of just 0.39 inches, or 1 centimeter.

The measurement was recorded in a study published in the Journal of Sexual Medicine, which analyzed data from over 15,000 men.

While a penis length of 1 centimeter may seem extremely small, it is important to note that this is an extremely rare condition known as micropenis.

Micropenis is a medical condition where the penis is abnormally small, often due to genetic or hormonal factors.

It affects around 0.6% of males worldwide and can cause fertility problems, sexual dysfunction, and psychological distress.

16: You Can Get an Erection After You Die

The penis can become erect even after death due to a phenomenon called “angel lust” or “death erection”.

This occurs when the blood flow to the penis is not restricted, leading to a buildup of blood and pressure, causing the penis to become erect.

The process of an erection involves the dilation of blood vessels in the penis, allowing for increased blood flow and filling of spongy tissue within the penis.

In death, the normal process of muscular and circulatory relaxation can be disrupted, leading to continued blood flow to the penis and subsequent erection.

Angel lust has been documented throughout history, with references in literature and art dating back centuries.

It is commonly observed in cases of hanging, particularly if the individual died due to asphyxiation, as this can cause blood to pool in the lower extremities.

17: Penis Transplants Can Be Successful (sometimes)

The first successful penis transplant was performed in 2014 in South Africa, by a team of surgeons led by Professor André van der Merwe.

The patient, a 21-year-old man, had his penis amputated three years prior due to complications during a traditional circumcision ceremony.

The surgery lasted nine hours, and the team of surgeons transplanted a penis from a deceased donor.

The procedure involved connecting blood vessels, nerves, and other tissues of the donor penis to those of the recipient, to restore urinary and sexual function.

The patient was able to achieve full erection and had successful sexual intercourse within six months of the transplant.

The success of this surgery was groundbreaking, as previous attempts at penis transplantation had been unsuccessful.

The first attempt was in China in 2006, where a patient’s new penis was removed two weeks after the transplant due to complications.

The second attempt was in 2009 in South Africa, but the patient’s body rejected the transplanted penis after three months.

Penis transplantation is a complex and delicate surgery, and the success of the procedure depends on many factors, including tissue matching, immunosuppression, and post-operative care.

It is also an option for patients who have undergone penis amputation due to cancer or trauma.

Penis Trivia -Conclusion

Your penis is a fascinating organ, be it large, small, or somewhere in between. 

We hope that this penis trivia has provided you with some additional insight into your own phallus and those of men worldwide.
