We teamed up with male sexual health expert Dr. Harry Fisch, board-certified urologist at New York Presbyterian Hospital and author of Size Matters, to write the ultimate quiz about dicks and balls. Good luck.

  1. 1. What is the average length of an erect penis?

    AndreyPopov / Thinkstock
    4.02 inches
    5.17 inches
    6.81 inches
    8.04 inches
    Correct!
    Wrong!

    The average length is 5.17 inches!

    There are actually a lot of studies on penis size. In 2014, researchers meta-analyzed the data from all these studies to find the average length of an erect penis, flaccid penis, and stretched flaccid penis — measured from root to tip. They only used studies where penis size was measured by a health professional (because people lie), the men were age 17 and up, and they excluded any penises with congenital defects or abnormalities. So this average measure doesn't speak for all peens, but most of them.

  2. 2. On average, how much does a penis shrink after an erection?

    rarrarorro / Thinkstock
    0–1/4 inch
    1–2 inches
    3–5 inches
    6–8 inches
    Correct!
    Wrong!

    The penis shrinks about 1–2 inches!

    Based on the same penis size studies, the average length of an erect penis is 5.17 inches and the average size of a flaccid penis (not stretched) is 3.61 inches. The difference would be 1.56 inches, so on average the penis shrinks about 1–2 inches after an erection. Obviously, this might vary among individuals, but it's usually around an inch and a half.

  3. 3. Can balls actually rotate inside the scrotum or is that a myth?

    franhermenegildo / Thinkstock
    Yes, this can happen!
    Nope, this is a myth!
    Correct!
    Wrong!

    Yes, balls can rotate inside the scrotum!

    It's called testicular torsion, and it's super painful. When the testicle rotates, it twists the spermatic cord, which supplies the testicles with blood. The twisting causes a sudden stop in blood flow, which results in swelling and extreme pain. Testicular torsion usually requires emergency surgery. It can happen during intense activities like sports, in cases of trauma, or even in your sleep — but in most cases the cause of testicular torsion is unknown. Ouch!

  4. 4. What are blue balls?

    Bruised scrotum from sexual activity
    Re-entry of sperm back into the testicles
    A completely made-up thing
    Buildup of blood and fluids in the testicles
    Correct!
    Wrong!

    Blue balls are the buildup of blood and fluids in the testicles!

    Blue balls happen when stimulation causes increased blood flow to the penis and the testicles. The penis becomes erect, and the testicles fill with blood and a buildup of other fluids, which make up the semen that will carry the sperm. If ejaculation doesn't occur, there's a huge increase in pressure and congestion in the testicles. They often feel tender, swollen, and sore. So yes, blue balls are a thing, and they really do hurt.

  5. 5. Are blue balls actually a blue or bluish color?

    instagram.com
    Yep
    Nope
    Correct!
    Wrong!

    Nope, blue balls aren't really blue!

    No, the testicles remain their usual color. But they are a bit swollen and firmer than normal. The term "blue balls" most likely comes from the fact that the sensation is similar to bruising.

  6. 6. Is it possible to urinate with an erection?

    Photon-Photos / Thinkstock
    Yes
    Nope
    Correct!
    Wrong!

    Yes, you can urinate with an erection.

    OK, so you can pee with an erection, but it's pretty uncomfortable. You just can't urinate with a full erection, which is when the penis is at its hardest state. At that point, a valve closes between the bladder and the urethra (which carries urine), to allow semen to pass through during ejaculation and not go back up into the bladder. So if the penis is fully hard and the valve is closed, you can't urinate. But if the penis relaxes and the erection goes down a bit, then the valve opens again and you can pee while the penis is still pretty hard. Still, peeing with a flaccid penis is really the way to go.

    Yes, you can urinate with an erection.

  7. 7. How many erections does a man have on average in one day?

    Tungus-ka / thinkstockphotos.com
    3 erections
    6 erections
    11 erections
    14 erections
    Correct!
    Wrong!

    A man has an average of 11 erections each day!

    Yup, 11 of them! There are different stages of erections, which range in hardness. So these random erections don't have to be rock-hard to count. And usually about half of the erections a man gets each day happen during sleep. They can obviously be triggered by stimulation or sexual activity, but they can also be totally random. So don't freak out — accidental boners are totally normal!

  8. 8. Do balls actually sweat?

    Zoonar/homydesign / thinkstockphotos.com
    Yes
    No
    Correct!
    Wrong!

    Yes, balls really do sweat!

    There are definitely sweat glands on the scrotum, and they produce a ton of sweat — especially since the crotch is a warm area that doesn't get a lot of ventilation. The crease between the testicles and the perineum is like an armpit, so it can feel like a furnace and drip with sweat down there. Under-ball sweat is basically like under-boob sweat, and it's very annoying in the summertime.

  9. 9. Is it possible to orgasm without ejaculating?

    jurisam / thinkstockphotos.com
    No
    Yes
    Correct!
    Wrong!

    Yes, it's possible to orgasm without ejaculating any semen!

    This isn’t super common, but it can happen with something called retrograde ejaculation, where the semen actually goes back up into the bladder instead of leaving the penis. This can happen as a result of an underlying neurological problem, diabetes, some medications, or if an infection or scar tissue is blocking the urethra. Some men can also train themselves with Kegels to orgasm without ejaculating by controlling a muscle that tightens the urethra so semen won’t exit.

    Yes, it's possible to orgasm without ejaculating any semen!

  10. 10. Is it possible to fracture an erect penis?

    instagram.com
    Yes
    No
    Correct!
    Wrong!

    Yes, you can fracture your penis!

    Yes. You can't break it (since there's no bone in the penis), but you can fracture it. There are two cylinders of tissue called the corpus cavernosum (like the inner tubes of tires), which fill with blood and get very hard during an erection. These can snap, usually if someone is on top and the penis doesn’t enter and there is too much weight and pressure. It’s rare, and it requires surgery to fix.

    Yes, you can fracture your penis!

  11. 11. Is it true that the more times you ejaculate in a day, the less semen comes out each time?

    releon8211 / thinkstockphotos.com
    Nope, that's a myth.
    Yes, that's true.
    Correct!
    Wrong!

    Yes, this is true!

    Semen is 95% fluids that help the sperm travel and support it with nutrients. The actual sperm only makes up a tiny amount. The fluids come from structures called the seminal vesicles, and these get depleted after each ejaculation because they have to produce more nutrient-rich fluids for the sperm each time, which they need some time and recovery to do. The average volume of semen is 3.5 ccs (0.71 teaspoons), so it'll be less than that each subsequent time.

    Yes, this is true!

  12. 12. Is it actually possible to sit on your testicles or is that an exaggeration?

    dolgachov / thinkstockphotos.com
    No, it's an exaggeration.
    Yes, you can sit on your testicles.
    Correct!
    Wrong!

    Yes, you can sit on your testicles!

    Most men don't have long enough testicles to fully sit on them, and they take measures to prevent this (i.e., "adjusting balls" in pants before sitting) because it’s super painful. But it's much more common in men with particularly large or low-hanging testicles. So be careful out there.

    Yes, you can sit on your testicles!

  13. 13. Is there a physiological explanation for morning wood, or is it just random?

    BrianAJackson / thinkstockphotos.com
    No, it's totally random.
    Yes, there's an actual physiological cause.
    Correct!
    Wrong!

    Yes, morning wood happens during REM sleep.

    Morning wood is technically a nocturnal erection, which men usually get around three to five times each night. Nocturnal erections happen during the rapid-eye-movement (REM) stage of sleep, when most dreaming occurs, because the body shuts off neurotransmitters like norepinephrine which are involved with the control of erections. The REM stages last around 30 minutes and include the period right before waking up, which is why you wake up from a dream with morning wood.

    Yes, morning wood happens during REM sleep.

  14. 14. Why are hot tubs bad for balls?

    razyph / thinkstockphotos.com
    The hot water increases sperm count.
    The hot water decreases sperm count.
    The hot water causes the testicles to shrink and harden over time.
    The hot water causes the scrotum to loosen and the testicles to drop.
    Correct!
    Wrong!

    Hot tubs decrease sperm count!

    The testicles hang outside of the body in the scrotum for a reason — to keep them at a stable, lower temperature that's optimal for sperm production. When you get in a hot tub, the heat warms up the skin and all the veins in the scrotum that supply the testicles with blood, raising the temperature so it’s too hot, decreasing the sperm count significantly.

  15. 15. Is it normal to have a curved penis?

    Zoonar RF / thinkstockphotos.com
    Yes
    No
    Correct!
    Wrong!

    Yes, it's normal to have a curved penis!

    A lot of men are born with a slightly curved penis, similar to the shape of a banana. Penises can curve in all different directions and shapes. However, it’s important to know when a curved penis isn’t normal. If the curve is sudden or it’s near a 90-degree angle, it could be Peyronie's disease — a buildup of scar tissue or plaque in the inner penile tissue that causes a bend. Peyronie's can happen with age or from trauma. So it's good to pay attention to any changes in shape or curvature.

    Yes, it's normal to have a curved penis!

  16. 16. Which of the following wouldn't cause the testicles to "retract" closer to the body?

    ananaline / thinkstockphotos.com
    Prostate stimulation
    Erection
    Cold temperatures
    Warm temperatures
    Correct!
    Wrong!

    Warm temperatures would not cause the testicles to retract!

    Cold temperatures cause the scrotum to retract to bring the testicles closer to the body for warmth so it maintains a stable temperature for sperm production. An erection and prostate stimulation are both part of sexual arousal, during which the scrotum thickens and tenses, bringing the testicles up toward the body. Warm temperatures would have the opposite effect, causing the scrotum to loosen so that the testicles hang lower, away from the body, to stay cool.

  17. 17. Does alcohol actually mess with the penis?

    draghicich / thinkstockphotos.com
    Yes
    No
    Correct!
    Wrong!

    Yes, alcohol definitely has an effect on the penis!

    Consuming too much alcohol can make it more difficult to get aroused, maintain an erection, and ejaculate. Alcohol usually does this because it acts as a depressant in your brain, delaying the signal between the penis and your nervous system. So it basically dulls the senses, making it more difficult to respond to sexual stimulation. So keep that in mind if you plan on getting it on after a night at the bar.
