15 Weird Facts About the Penis

Summary

In this episode of *The Infographics Show*, we explore bizarre and surprising facts about the penis. Topics covered include the historical presence of penile spines in humans, the truth behind the myth that shoe size correlates with penis size, the effects of smoking and weight gain on size, and even the potential for erections in space. From the mystery of circumcision to the odd origins of cornflakes, the episode delves into quirky medical facts, including the rare condition of diphallus, and ends with some truly strange historical anecdotes about Napoleon's supposed 'imperial' organ.

Takeaways

• 😀 Penile spines once existed in human ancestors but were lost over time, likely due to the shift toward monogamous relationships.
• 😀 Human penis size varies widely, but studies show women may prefer a larger size for deeper vaginal stimulation, though technique is also important.
• 😀 Smoking and weight gain can cause temporary shrinkage of the penis by affecting blood circulation or increasing belly fat.
• 😀 Penile fractures, which happen when the protective tunica albuginea tears, can cause intense pain and bruising—often due to energetic sexual activity or injury.
• 😀 Diphallus, a rare condition where a person is born with two penises, occurs in 1 in 5-6 million births and often requires surgery for correction.
• 😀 Men can experience erections multiple times during sleep due to REM cycles, which is normal and not necessarily linked to dreams.
• 😀 Blue balls, or prostatic congestion, is real but can be relieved through orgasm, aspirin, or a warm shower.
• 😀 Penis shape can vary greatly, with erections often pointing in different directions, and a curve of up to 30 degrees is considered normal.
• 😀 In space, gravity affects blood flow, making it more difficult to achieve an erection, and sex in space is still an area of limited research.
• 😀 Cornflakes were originally created in the 1890s by Dr. John Harvey Kellogg to curb masturbation, a belief rooted in his religious and medical views.
• 😀 The story of Napoleon Bonaparte's amputated penis, which was sold at auction in the 1970s, remains controversial, with doubts about its authenticity.

Q & A

What is the origin of penile spines in humans and why are they no longer present?

Penile spines were once present in human ancestors, specifically a common ancestor of chimpanzees and humans, about six million years ago. These spines may have helped increase mating success by making erections faster and promoting promiscuity. However, due to genetic changes over time, and possibly due to the development of more monogamous human relationships, these spines have disappeared in modern humans.

How does penis size relate to sexual satisfaction, according to the script?

While some women report a preference for longer penises due to deeper stimulation during vaginal intercourse, the script emphasizes that sexual satisfaction also depends on factors like technique, as well as individual preferences. It also notes that size is often exaggerated in myths, with some men embracing their natural size regardless.

Is there a connection between shoe size and penis size?

No, the script debunks the common myth that shoe size correlates with penis size. A study published by BJU International in 2002 confirmed there is no scientific basis for this connection.

What factors can cause permanent shrinkage of the penis?

Smoking can cause permanent shrinkage of the penis, as it impacts blood flow by calcifying blood vessels. Weight gain can also make the penis appear smaller, even though it may not actually shrink, due to the abdominal fat pulling it inward.

What is Peyronie’s disease and how does it affect the penis?

Peyronie’s disease occurs when scar tissue, known as plaque, forms under the skin of the penis, causing it to bend. This condition can lead to pain, erectile dysfunction, and is more common in older men or those with a history of certain medical conditions, such as diabetes or prostate cancer.

What is diphallus, and how rare is it?

Diphallus is a rare condition where a person is born with two penises. It occurs in approximately 1 in 5 to 6 million live births. In most cases, surgical intervention is required, and the condition may not involve two fully formed penises.

Why does an erection sometimes occur during sleep, and is it normal?

Erections during sleep, specifically during REM (Rapid Eye Movement) sleep, are completely normal. It’s not necessarily a sign of sexual arousal but rather a natural bodily function. On average, men experience 3 to 4 erections per night during this sleep phase.

Is 'blue balls' a real condition, and how is it treated?

'Blue balls,' medically known as prostatic congestion, occurs when the prostate becomes swollen due to excess fluid and blood. It can cause discomfort and is often relieved through orgasm, but simple remedies like aspirin or a warm shower can also help alleviate the discomfort.

What does the penile raphe signify?

The penile raphe is a seam along the penis that marks the line where male and female anatomical structures diverged in utero. It’s a remnant of the labial fusion that occurs in the early stages of fetal development before the sex organs differentiate.

What is the historical connection between cornflakes and the prevention of masturbation?

Cornflakes were created by Dr. John Harvey Kellogg in the late 19th century as part of his belief that bland food would curb unhealthy sexual urges, including masturbation. Kellogg was influenced by his religious views and thought that a plain diet would promote piety and purity.
