45 Differences Between Men and Women – Scientific Facts

The differences between men and women are pretty fundamental. This has been proved by a lot of scientific research. But with that being said, have you ever wondered what are the reasons behind such differences? Obviously, there are some genuine differences in the biology, chemistry and mental make-up of both the sexes. So, what we have done is we have created a list of 45 such differences. Have a look at them and tell us how many you were aware of –

1. Men Have A Better Acoustic Size Judgement

via

Men have a particular aptitude for voice recognition. They have been shown to correctly guess a person’s general appearance, using their voice, at about 1.5 times the rate that women are able to. Man, that is awesome!

2. Men And Women See Things Differently

via

The different perspectives of men and women can be attributed to their vision capabilities. Men have thicker retinas and larger M cells than women. The M cells are responsible for tracking the movement of objects. Women have more P cells. These are responsible for identifying objects, as well as analyzing textures and colors.

3. Women Are More Right Minded As Compared To Men

via

Men use mostly the left hemisphere of the brain, while women tend to employ both hemispheres. Girls commonly use more words than their male counterparts if they are asked to describe something. Men, on the other hand, tend to have their verbal ability concentrated in only the left hemisphere.

4. Differences Between Male And Female Brains Are Formed Before Birth

via

Male and female fetuses start showing brain differences as early as 26 weeks. At that stage, female brains start developing a thicker corpus callosum, which is the part of the brain that connects the left and right hemisphere.

5. Women Tend To Stay Cool As A Cucumber Under Stress

via

During a stressful situation, both men and women release the hormone oxytocin. Female estrogen combines with the oxytocin to create a calming effect. Testosterone to oxytocin has a tendency to make men more aggressive. Brain chemistry may say a lot of things, but it has made this stereotype a well-cemented fact.

6. 3-Dimensional Thinking

via

Men are better able to think of objects three-dimensionally than women are. This skill may have been developed back in the days when men hunted and regularly participated in competitive battles.

7. Men Understand Faces And Moving Objects Easily

via

In a female baby’s first few months of life, their eye contact will increase by over 400%, and a boy’s will show significantly less improvement. In a study done on 100 babies on the day of their birth, girls were found to prefer looking at a young woman’s faces, while boys preferred moving objects.

8. Men Have A More Mathematical Mind Than Women

via

The area of the brain that is thought to influence mathematical ability is larger in men than in women. The brain areas that control math and geometry skills also mature about four years earlier in men.

9. Women Mostly Have A Spare Chromosome

via

Having a spare chromosome is good news. Read ahead and you will know why. Most babies that are born with defects and disabilities are male. One major reason for this is that females have a spare X chromosome. Essentially, this results in redundancy that protects against certain recessive defects caused by genes on the X chromosome.

10. Men Have More Popped Up Veins

via

The more muscle mass a person has, the more blood is needed to fuel it. As muscle mass builds, so do veins. Since men on average have more muscle mass than females, they tend to have more prominent veins.

11. Women Remember Things Better Than Men

via

Women are better at recalling where things are than men. That is why women are more likely to navigate using landmarks. On the other hand, men navigate using direction and distances. So, if you have to reach a place easily, it is better to ask a woman for directions and not a man.

12. Women Hear Noises As Clearly As A Bat

via

No, really. A women’s perception of sound is much better than men’s. Women have 11% more neurons than men in those brain centers that control language and hearing. Not only do women hear better than men, but they can also better distinguish between a broader range of emotional tones, like crying, laughing or even scowling.

13. Brow Bossing

via

Even the space between the brows of men and women is different. In fact, there are three major differences between a male and a female forehead. Men tend to have a ridge of bone running across the forehead at brow level called brow bossing. Women’s foreheads are smoother, flatter, and have no boss.

14. Men And Women Store Fat Differently

via

Men and women are programmed to store fat differently. Women tend to store fat in a ring shape around the abdomen and tend to store it in their hips, thighs, buttocks, and lower abdomen. Men tend to store fat in the upper body, and especially the abdomen. That is why men get a beer belly easily.

15. Women Feel More Pain

via

Women can genuinely feel more pain than men. That is why they react a lot when they get hurt. But that does not mean that you should question a woman’s pain tolerance. While experiencing pain, a woman’s left amygdala or the part of the brain that is associated with internal functions gets activated. When men experience pain, the right amygdala is activated.

16. Women Are Chronic Worriers

via

Women worry more than men. There is no single reason for this, but hormone differences and environmental factors play a part. On the bright side, worrying gives women an advantage when it comes to foreseeing and handling problems.

17. Men Don’t Ignore Women, But Their Brain Does

via

During male fetal development, there are a lot of biological changes. The testosterone impacts the formation of the auditory system and causes the brain to block out unwanted noise and repeated sounds. When a person repeats themselves several times, the male brain registers it as an “unwanted repetitious acoustic stimuli.” Women do not have this ability.

18. Better Spatial Sense

via

Men have a better understanding of space than women. That is why they are able to park better or store more efficiently than women. The science behind this is that a man’s parietal regions are thinner than a woman’s. This makes it easier for them to visualize rotating 3D objects.

19. Finger Length Is Responsible For The Secretion Of Hormones

via

What? Now, that is a mind-boggling fact. The hormones testosterone and estrogen control the genes that determine finger length. More testosterone is generally equated with a longer ring finger, while estrogen is associated with a longer index finger.

20. Conflict And Competition

via

Have you seen a couple’s fight? Have you noticed how the men react emotionally when compared to a woman? Here’s the reason behind it. Men get a positive chemical boost from conflict and competition, while conflict elicits negative chemical reactions in women, creating fear, stress, and sadness. This ties back to nature, where the females of certain species rely on social ties for survival.

21. Who’s Better At Colour Detection?

via

So who do you think sees color better? Of course, it is the women who are more sensitive to colors. Women are better able to detect shade variations in colors than men. Some scientists believe that sex hormones are behind the differences, as male sex hormones can change the development of the visual cortex. Women have been food gatherers all their lives, so this could be a possible reason for their color sensitivity.

22. Processing Emotion

via

Men and women tend to react differently to emotions. In adult men and women, the brain activity associated with negative emotion moves from the primitive area of the brain into the cerebral cortex where language and reasoning centers are located, but this only happens in girls. Women express emotion better than men, who rarely like to talk about it.

23. Neurological Disorders

via

Male brains have more mass and hence, the chance of having mental flaws increases. More men than women suffer from neurological disorders like dyslexia and autism. Studies have found that this is a matter of genetics. Male brains are more prone to genetic flaws, while women require more extreme genetic mutations to develop the same conditions.

24. Consonants and Vowels

via

Men and women react to sounds in different ways. Men can listen to infrasonic sounds better whereas women can process ultrasonic sounds in a better way. As men and women age, men tend to have more difficulty hearing high-pitched sounds (consonants), while women struggle with low-pitch sounds (vowels).

25. The 1000 Gene Difference In The Livers Of Men And Women

via

Wondered why ladies have a worse hangover than men? Here’s the answer. Women have a harder time metabolizing alcohol because they have less of a liver enzyme that breaks it down. There is a difference of 1000 genes in male and female livers. These extra genes help men process alcohol faster. This means women get drunk more easily than men.

26. The Effect Of Getting No Sleep On Men And Women

via

A research conducted by Duke University revealed that men can handle sleep deprivation better than the women do. If women don’t get the sleep they need, they tend to suffer both mentally and physically. They are at higher risk of developing heart disease, depression, or blood clots, while men suffer fewer consequences. So, sleep all you can, women!

27. Aggression Styles – Physical vs Verbal

via

The ways in which men and women express their anger is actually different. Men tend to express aggression physically, while women express it verbally. This is because a man’s aggression pathway is more directly linked to the brain areas for physical activity, and a woman’s is more closely linked to areas of verbal function.

28. Cold Feet

via

Have you wondered why your Mom, sister or wife have cold feet most of the time? It’s because of the body’s biochemical reactions. Blood flow in women is more concentrated around the lower extremities, while in men it’s spread more evenly. This is why women’s hands and feet get colder than men’s.

29. Water In The Blood

via

A woman’s blood is thinner than a man’s. A woman’s blood contains more water and 20% fewer red blood cells than a man’s. That is the reason why women have less probability of getting a heart attack than men. That is also the reason why women tend to urinate a lot more than men.

30. Women Are Not As Sad As You Think

via

The hormone that produces breast milk in women, Prolactin, also produces tears. Women naturally have more of that hormone than men. So, their bodies also produce tears more easily than men. Some women have higher levels of the hormone, which makes them cry at the smallest stimulation. But that does not mean that they are in grief.

31. Women Are Born Multitaskers – Really?

via

People think that men are better at multitasking, but in reality, it is actually the opposite. The accumulated data for researches so far suggests that men and women are equally matched when it comes to their multitasking abilities, and as they age, they lose that ability at equal rates. But women fare a tad better because the loss is not that steep as it is in men.

32. Women Are More Linguistically Inclined

via

Women have larger frontal and temporal areas of the cortex, which are thought to influence language skills. These parts of the brain mature about 6 years earlier in girls than in boys. So, it is easier for them to master languages. It comes as no surprise that they can even communicate through their eyes.

33. Women Have A Neater Hand

via

Girls develop fine motor skills earlier than boys do, which lends scientific validity to the stereotype that women have neater handwriting than men. Men and women also grip writing implements differently, which also affects motor skills when writing.

34. Women Have An Incredible Shrinking Brain

via

The female brain is more flexible than the male brain, and during pregnancy, women experience a major restructuring of the brain. Stress circuits are suppressed, the cortex increases in size, and the rest of the brain experiences shrinkage. No brain cells are lost in the transition, but new networks form and pathways change until the brain returns to normal around six months after delivery.

35. Brain Usage – Both Sides vs One Side

via

All of us know that men and women use brains in different ways. When it comes to responding to emotional experiences, men only use one side of the brain while women use both sides. Women also retain a stronger memory for emotional events than men.

36. Men Are Better At Sniffing Out Adultery

via

A study published in the Journal of Human Nature found that men are better at reading subtle clues about their partner’s infidelity. Studies have also revealed that men are more bothered by sexual infidelity, while women are upset by emotional infidelity. Men are also more likely than women to falsely suspect cheating.

37. The Big Sniffer

via

Men have noses that are around 10% larger than women. The masculine predisposition to elephant-style snouts is a reality. This can be related to their larger muscle mass. It simply requires more oxygen for men to maintain muscle tissue growth and maintenance. A bigger requirement for oxygen intake means a need for bigger nostrils.

38. Bigger Hearts

via

No! Is that true? Yes, of course, it is! Men literally have bigger hearts than women. They have a volume that is around 70% more than that of a woman’s. A female heart is about 2/3 the size of a man’s and beats fewer times per minute.

39. Women Have Looser Ligaments

via

The muscular structure in a woman’s body is way different than a man’s. Women have looser ligaments than men, which gives them a greater range of movement, and makes it easier to do things like the splits. The downside to this greater flexibility is that women are at greater risk of joint injuries. So, all the ladies out there – take care of your bodies.

40. Women Are Thin-Skinned

via

That is the reason why women have a softer and more tender skin when compared to men. Women have thinner skin than men and are thus more prone to develop lines and wrinkles as they lose collagen from aging. Men also have a higher collagen density, which makes them look younger longer.

41. Women Have A Longer Lifespan

via

Women have an average life expectancy that is 5.3 years longer than men, largely due to better immunity, reduced risk for blood disease, and lower risk-taking. So, if you say that men live dangerous lives, then you are not wrong. Moreover, men tend to smoke a lot, which can affect their life expectancy as well.

42. Men Have A Tunnel Vision

via

Men use 7 times more gray matter for activity than women. The gray matter areas of the brain are the information and action-processing areas, which can create a kind of tunnel vision in men when they are doing something. So, if you thought that men had razor-sharp focus, you now know the reason for it.

43. Response To Unfriendly Faces Is Different

via

During puberty, a lot of biological and biochemical changes occur in a boy’s and girl’s bodies. There is a hormone called vasopressin, which works with testosterone in males to influence a boy’s perception of faces. In one study, girls who were given a dose of vasopressin were more likely to rate a neutral face as friendly, while boys rated neutral faces as unfriendly or hostile.

44. Both Sexes React Differently To An Orgasm

via

Both sexes release oxytocin during orgasm. Oxytocin is also known as the “cuddle chemical”. It makes people want to bond. However, men have higher testosterone levels which not only can dull the effects of oxytocin but also can encourage seeking out the next high. Researchers have pointed out that men don’t always want to sleep. In fact, after having an orgasm, they often want to eat, drink, or smoke, seeking out the next reward.

45. Overall, Both Sexes Have Equal Intelligence

via

Overall, men and women have an equal level of intelligence. While Men have physically larger brains than women, size does not directly correlate with intelligence. What’s learned by experience or study helps forge neuronal connections, which in turn determines intelligence.
