Amazing Facts About Male Body - Photo KnowInsiders

Men can be so mysterious to women. And while there's much about the male sex that remains perplexing, we got the low down on some interesting facts about men's bodies. We talked with various experts who clued us in on why men have larger teeth and eyebrows, the reason they're always so warm, and what exactly is happening below the belt. For some similar info, but about the opposite sex.

Top 15 Amazing Facts About Male Body:

1.Men can produce milk

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.

2.Female origins

All human beings in the world began their existence as females. X and Y chromosomes are responsible for determining an individual's sex. If two X chromosomes join together during conception, a girl is produced; if X and Y chromosomes join together, a boy appears.

During the first 5-6 weeks, the Y chromosome is inactive. Until it begins to function, the embryo begins to develop into a girl.

3.They Have the Ability to Slow the Aging Process—if They're Careful

From the neck up, men tend to age better than women: They lose collagen density more slowly than women, which means their skin resists wrinkles and sagging as they get older. Dermatologists claim that both men and women lose about 1 percent of collagen per year after age 20, but the loss accelerates significantly in women when they hit menopause. But because men are often more lax about taking care of their skin than women are, they're more susceptible to sun damage and shaving-related surface trauma, and this can negate their natural advantage. Daily use of broad-spectrum sunscreen goes a long way toward helping men retain their skin's suppleness and vitality.

4.The Adam's apple

Have you ever wondered what the Adam's apple is for, and why men have larger ones than women? Women have only a small protrusion on their necks, made up of thyroid cartilage, the only purpose of which is to protect the vocal chords.

This thyroid cartilage is also responsible for the higher tone of people's voices. During a person's teenage years, its angle in relation to the annular cartilage changes, forming an Adam's apple and leading to the so-called "breaking" of a person's voice. This angle is smaller in men than in women, making the protrusion larger and their voices lower.

5.Men See Fewer Shades Of Color

Compared to women, men may see fewer shades of color due to the fact they have fewer retinal cones in their eyes. "This is because retinal cones are on the X chromosome, which men only have one of," Myra says. "Men, however, have more testosterone in their visual cortexes, meaning they sense brightness better than women." Fascinating, right?

Being aware of these things can teach us so much about each other, in terms of how our bodies work, which in turn can make us that more knowledge about health overall.

6.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.

7.Men typically have darker hair than women

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.

8.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.

9.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.

10.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.

11.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.

12.Male babies can get erections in the womb

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.

13.Men have bigger jawbones, cheeks, and eyebrows

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.

14.Baldness

It's pleasant to think that the genetic inclination to go bald is passed on exclusively by the mother's X chromosomes, but this is not entirely the case. There are other, no less important factors.

If a man's father is bald, then his chances of also losing his hair increase by 60%. The activity of male hormones also affects hair follicles in such a way that the body gradually loses its ability to produce new hair. Stress and a poor diet also significantly increase the risk of going bald.

15. Premenstrual syndrome

This might be very surprising to some, but 26% of men also experience PMS.

During these periods, a man becomes more sensitive, irritable, and hungry and can even experience stomach cramps. That is, he experiences exactly the same symptoms as a woman does.
