For all the attention they direct below the belt, most men actually know very little about their penises. Here’s the knowledge you need to keep yours healthy, strong, and ready for action-for life.
1. Every p*nis was a cli.toris. Every p*nis in the womb starts as a cli.toris before hormones ‘s*x’ the brain of the to-be male. The man-hood retains the mark of its female heritage: its dark underskin and the thin ridge or seam, known as the raphe, which runs from scrotum to anus, are remnants of the fusion of the vag.inal lips.
2. P3nises used to have spines. Though they were lost before Neanderthals and modern humans diverged. Scientists are still not quite certain of their purpose, but they speculate that it apparently quickened the pace of an erection and is more common in promiscuous species (such as cats).
3. Fetuses can have er3ctions! Male fetuses can have er3ction during the third trimester, according to ultrasound scans.
4. No brain is necessary for eja.culation: the order to release comes from the spinal cord, not the brain.
5. King of ancient tribes ate p*nises: In ancient tribes, the king would often eat the p*nis of his predecessor to apparently absorb his holy power. This practice was allegedly banned by the ancient Hebrews.
6. Testifying on testicles: In pre-biblical times, men would swear on their own p*nises. The word “testify” is derived from a Roman legal practice of swearing on one’s testicles. The word “man-hood” comes from the Latin word for “tail”.
7. “Shaved” guardians in Muslim empires: In great Muslim empires, there would be a guardian assigned to each harem’s bed. The guardians had to be “shaved,” which meant having his testicles and p*nis removed.
8. King Fatefehi of Tonga: between the years of 1770 and 1784, he apparently deflowered 37,800 women.
9. Diphallus is a rare condition that affects one in 5-6 million males. It’s when a man is born with two p*nises. Unfortunately, it’s rare that both are fully functional, and it often comes in tandem with other deformities that also require surgery.
10. P*nises can actually break: Every year, hundreds of men break their erect p*nis, researchers say. Most do so during “violent intercourse.” But there are also cases where men snap their member – indeed, specialists note that such incidents are accompanied by an audible crack – by falling out of bed with an erection. The cure for a broken man-hood? Six weeks of bed rest with a man-hood splint.
11. Smoking can shorten your man-hood by as much as a centimeter. Erections are all about good bloodflow, and lighting up calcifies blood vessels, stifling erectile circulation.
12. The foreskin has an abundance of Langerhans cells, which are immune cells that are infiltrated by HIV. This may explain why circumcised men in Africa have a 60% lower rate of HIV infection from heterosexual intercourse.
13. A healthy male averages 11 erections per day-nine of them while asleep. After ejaculating, it can take him anywhere from two minutes to two weeks to achieve another erection.
14. From shower to grower: On average, a limp man-hood will increase in volume 300% when it is erect. It will also contain more than eight to ten times its normal amount of blood.
15. Jonah Falcon, a 42-years-old man with a 9-inch man-hood (22.86 cm; 13.5 inches, or over 34 cm when hard). He’s the man with the world’s largest p*nis.
16. Animals with the biggest and smallest p*nises: the Blue Whale is the animal with the biggest recorded p*nis to date, at 8 feet (over 2 m) long. The adult male elephant has the biggest recorded p*nis for land animals, at 6 feet (1.8288 m, and S-shaped when erect). And coming in with the smallest man-hood is the shrew, at .2 inches (0.5 cm).
17. Koro, a culture-specific syndrome, where a man (or a woman) is overcome with a debilitating fear that his p*nis (or her nipples) is shrinking and will eventually disappear. Interestingly, this fear is borne out of no real proof or evidence. It is also known as “man-hood panic” and has been said to provoke mass hysteria.
18. Semen can cure depression: Apparently, semen contains chemicals that elevate mood, increase affection, induce sleep, and contain at least three antidepressants. It also contains cortisol, which is known to increase affection; as well as estrone, which elevates mood; oxytocin, which also elevates mood; thyrotropin-releasing hormone, which is another antidepressant; melatonin, which is a sleep aid; and serotonin, which is a well-known antidepressant neurotransmitter.
