If you think you know more blonde-haired women than men, you're probably right. According to Joseph Hart, RN, director of operations at MAXIM Hair Restoration, "Men will typically have darker hair than their female counterparts, particularly once the individual has passed through puberty and this trend will continue with age." Hart says this phenomenon is due to men's higher levels of melanin, which influences people's skin tone, hair color, and eye color.

2 | Men's teeth are larger than women's.

One might assume men's teeth would be larger, as they are generally "bigger" human beings. Pia Lieb, DDS, founder of Cosmetic Dentistry Center NYC says this is actually true. She points to studies that found men’s teeth do in fact, tend to be larger, than women's—especially the canine teeth.

What makes a face masculine or feminine? There are actually a couple of tangible factors that contribute to a standard masculine or feminine appearance. Kimberly Langdon, OBGYN, and medical advisor at Medzino Health says, "Men have bigger jawbones, cheeks, and brows while women have wider faces, bigger lips, and higher eyebrows." A study published by Frontiers of Psychology found that eyebrow thickness, jawbone prominence, and face height was a prominent part of masculinity and perceived attractiveness.

4 | Men snore more than women.

This fact is probably unsurprising to anyone who has spent the night beside a loudly snoring man. "Snoring, because it comes from your nose and your mouth—is typically more common in men due to abdominal body fat." The American Academy of Sleep Medicine reported that about 40 percent of men are habitual snorers, while only 24 percent of women are habitual snorers.

5 | Men process threats better.

While women have a larger hippocampus and prefrontal cortex, which makes them more detail-oriented by nature, men have a large amygdala. Langdon says men's sizable amygdala could be responsible for their stronger ability to process threats.

From as early as 16 weeks old, fetuses have been observed with brief protuberances. While there are not enough studies to assert why this occurs, some point to the age-old "use it or lose it" theory— The Los Angeles Times reported that periodic movements are necessary to help the penile tissue stay oxygenated and healthy.

This myth has been passed around for many years, but a study published by BJU International decided to put this theory to the test. For the study, "two urologists measured the stretched penile length of 104 men and related this to their shoe size." The outcome? There was no scientific correlation between the two body parts.

8 | The human penis may have evolved because of competition.

We knew men were competitive, but this evolutionary adaptation theory shows just how ingrained that particular edge really might be. A study published by Evolutionary Psychology suggests "the human penis may have evolved to compete with sperm from males from other species by displacing rival semen from the cervical end of the vagina prior to ejaculation." The shape of the human penis varies greatly from other species, and this might be why, the study says.

Have you ever wondered why men have nipples? The short answer is that nipples develop in the womb before the embryo becomes distinctly male or female, according to Healthline. It turns out men also have mammary glands—the organ responsible for creating milk. Although men can produce milk, it generally only occurs when something is wrong, most commonly an interference with prolactin—the hormone needed to produce milk, according to Scientific American.

10 | Men get yeast infections.

While yeast infections are significantly more common in women—75 percent of women will have one in their lifetime—men can get one of these pesky infections as well.  Additionally, male yeast infections "can lead to a condition known as  balanitis—inflammation of the head of the penis," according to Mayo Clinic.

Contrary to popular belief, sperm—the cell seeking the egg to reproduce—is not the only component of semen. "Most of the fluid in semen is made up of secretions from male reproductive organs. Semen contains citric acid, free amino acids, fructose, enzymes, phosphorylcholine, prostaglandin, potassium, and zinc," according to News-Medical.

12 | Men's diet effects their sperm count.

"A study of 250 men who had sperm analyzed at a fertility clinic showed that men who ate higher amounts of fruits and veggies, particularly green leafy vegetables and beans (legumes), had higher sperm concentrations and better sperm motility compared to men who ate less of these foods," according to the University of Chicago Medicine. Other foods that boost sperm count include walnuts and fish. On the other hand, foods that can dilute the supply include processed meats, trans fats, soy, pesticides, and high-fat dairy products.

13 | Men also have a G-spot.

It may not be as centrally located as a female's, but it does exist. Men's prostate—a gland between the bladder and the penis—is considered by many doctors and health experts to be the male equivalent of a G-spot, according to Men's Health. Allegedly, the outcome of arousing the prostate g-spot is a much more intense orgasm than

14 | Men's skin is thicker than women's.

This fact isn't referring to the age-old idiom. Due to the amount of testosterone men have pulsing through them, their skin is literally thicker than women's. "Androgen (testosterone) stimulation causes an increase in skin thickness, which accounts for why a man's skin is about 25 percent thicker than a woman's," according to Dermalogica. Not only is a man's skin thicker, but the texture is also tougher.

15 | Male orgasms typically last half as long as female orgasms.

While it may often be easier for men to orgasm than it is for women, once it happens, it's usually only half as long. According to Medical News Today, the average male orgasm "lasts for 10-30 seconds," while the average female orgasm "lasts for 13-51 seconds."

16 | Erectile dysfunction can be a side effect of many things.

Erectile dysfunction (ED) can be a result of a lot of a variety of issues, many of them serious health conditions. According to New York Urology Specialists, common causes of ED include, "high blood pressure, cholesterol, obesity, and smoking." So if you know a man experiencing ED, understand it is likely rooted in something unrelated to sexual chemistry.

17 | Men stay warm more easily.

If you've ever looked at a group of male friends and wondered why they were wearing shorts in the middle of winter, their lower body temperature is likely a factor. Since men tend to have more muscle, they have a lower resting body temperature than women, which keeps them warmer, according to Doctors of Osteopathic Medicine.
