Top 10 Interesting Facts About Penises

The penis is a unique and complex organ that’s shrouded in mystery and unknown. Whether you’re curious about the correlation between shoe size and penis size or want to know the truth about the “morning wood,” this article delves into the fascinating world of penises, offering valuable insights along the way.

Interesting Facts About Penises

Shoe Size Does Not Correlate with Penis Size

One of the most common myths about penis size is the belief that a man’s shoe size indicates his penis size. This even gave rise to sayings such as, “Show me a man’s shoe and I’ll tell you the size of his penis!” and “The bigger the feet, the bigger the meat.” While this holds some truth, it’s far from accurate, as no scientific evidence supports the correlation between the two body parts. The size of a man’s penis is determined by genetics, individual growth patterns, and hormonal factors that are not reflected in the size of the feet.

Over the years, several studies have debunked the myth linking shoe size to penis size. One such study published in the British Journal of Urology International, which measured the shoe size of 104 men, “found no statistically significant correlation between shoe size and stretched penile length” [1]. So, the next time you encounter someone joking about shoe size and penis size, you can confidently debunk the myth with real facts.

The Penis Is Twice As Big As You Think

One fun and intriguing fact about the penis many don’t know is that it is typically about twice as long as it appears when flaccid. This is because a significant portion of the penis is often folded in, not visible externally. Upon sexual stimulation, blood flow causes it to extend and become erect, revealing its full length.

Research has shown that the average flaccid penis length ranges from 2.8 to 3.9 inches, while its average length when erect ranges from 4.7 to 6.3 inches. This means that the organ can increase in size by up to 2 to 3 inches when erect [2]. Many men often measure their penis when it’s flaccid and may feel self-conscious about its size; however, the true measure of its size is taken when it is erect.

The Penis Can Be Broken

One of the lesser-known facts about the male organ is that it can actually break, a condition that’s known medically as penile fracture. While there are no bones in it, the tunica albuginea, a fibrous covering that surrounds the erectile tissue, can tear, resembling a fracture. This injury can occur when an erect penis is bent forcefully, particularly during rough sexual activity, or from blunt force trauma, such as impact against a hard surface.

Typically, when a penile fracture occurs, there’s usually a cracking sound followed by severe pain, swelling, bruising, and difficulty in achieving an erection. It’s important to seek urgent medical attention to repair the tear and prevent complications such as curvature or erectile dysfunction (ED) [3].

Erection Begins at an Early Age

Another interesting fact about the penis is that erection can begin at a surprisingly early age. Even more shocking is the discovery that male fetuses can also experience erections while still in the womb, as evidenced by ultrasound images.

However, it’s worth noting that erections in infants and young children are not typically linked to sexual arousal but are rather a physiological response to stimulation. As boys reach puberty, erections become more closely associated with sexual activity [4].

“Morning Wood” Is Normal

For many men, one of the most intriguing things related to the penis is the phenomenon known as “morning wood.” This term refers to the spontaneous erection that most men experience upon waking up in the morning. While some may feel embarrassed by it, it’s actually a completely normal and healthy physiological response.

Morning erections take place during the rapid eye movement (REM) stage of sleep. It’s worth noting that they are not necessarily associated with sexual arousal or dreams of a sexual nature. Instead, they are believed to be a result of hormonal changes that typically occur during sleep, combined with the relaxation of the body’s sympathetic nervous system. “Morning wood” serves as an indicator of healthy erectile function and overall physiological well-being.

The Average Penis Size Is Not As Large As It Is Believed to Be

Despite the common beliefs and stereotypes pushed by media and pop culture, the average penis size is not as large as many people think. This misconception often leads to unrealistic expectations and unnecessary anxiety for men regarding their own size.

According to a study published in the British Journal of Urology International, the average erect penis is approximately 5.2 inches in length and 4.6 inches in circumference. Additionally, it suggests that the flaccid organ size is around 3.6 inches in length and 3.7 inches in circumference. It’s worth noting that penis size may vary widely among individuals and can be influenced by factors such as ethnicity, genetics, and overall body size.

Based on these findings, a big penis, while answers may be subjective, is one that measures 6 inches and above when erect [5].

Erectile Dysfunction (ED) Also Affects Young Men

Contrary to popular belief, ED isn’t solely confined to older men; it also affects younger individuals. Various reasons contribute to ED in younger men, including psychological factors such as anxiety, stress, performance anxiety, and depression. Lifestyle choices such as drug use, excessive alcohol consumption, and a lack of exercise can also contribute to ED. What’s more, it is also often caused by underlying medical conditions such as cardiovascular diseases, hormonal imbalances, and diabetes.

It’s important to seek immediate medical attention once ED is observed in younger individuals, as it may be indicative of a serious underlying medical condition. Additionally, leaving it unaddressed can negatively affect relationships, self-esteem, and overall quality of life.

There Is a Correct Way to Measure a Penis

While it may seem like a straightforward task, most men don’t know how to measure their penises. Contrary to popular belief, measuring from the tip or the side might not give the most accurate results. The correct way to measure the longest part is from the base to the top of the organ. For girth, measure the circumference at the widest point. For the most accurate result, the measurement is taken when the penis is erect [6].

Penis May Be a “Grower” or a “Shower”

Did you know that penises are typically categorized into 2 types: “growers” and “showers”? A “grower” is a penis that significantly increases in size when erect compared to when it is flaccid. These individuals may surprise their partners with a substantial increase in size upon arousal. On the other hand, a “shower” is a penis that remains relatively the same size whether flaccid or erect, appearing large even when not aroused.

Regardless of whether someone is classified as a “grower” or a “shower,” it doesn’t affect sexual performance or satisfaction. It’s simply a matter of genetics and anatomy, and neither category is considered better or more desirable than the other [7].

The Size of the Penis That Women Prefer Varies

When it comes to sexual preferences, women’s preferences for penis size vary greatly. While some may prefer a larger organ for enhanced pleasure, others may find it intimidating and even uncomfortable. Conversely, some women may find smaller or average-sized penises more comfortable and pleasurable. It’s worth noting that sexual satisfaction is not solely determined by penis size; other factors such as communication, emotional connection, and sexual skills play a huge role.


By sharing these interesting facts, we aim to dispel common misconceptions surrounding the penis and shed light on some surprising truths. So, the next time you engage in a conversation about penises with anyone, you’ll have some interesting, cool, and accurate insights to share. In addition to that, having a good understanding of the facts about penis size and sexual health can help you make informed decisions and engage in meaningful discussions on the topic.
