Everyone knows that there are significant differences between male and female organisms, which are also observed in psychology.
No wonder there is an expression: “A man from Mars, a woman from Venus”, which in a metaphorical sense suggests that the difference between the sexes is so significant that men and women can be considered immigrants from different planets.
In addition to the obvious differences between the sexes, there are those that we never thought about. In our article, you can find 10 little-known facts about the biological differences between men and women.
10. Gene protection
New Zealand scientists have found that female genes are much stronger than male genes, and they affect life expectancy. Ladies are able to live longer than gentlemen thanks to good indicators of gene immunity.
Defects in the field of genetics that a mother has are not passed on to daughters, but to sons. Researchers noted in their work that the fairer sex in the body is immune to various gene mutations and defects, so serious diseases are transmitted through the male line in the genus.
Also, scientific studies have proved that men need to marry, not be polygamous, as this will allow them to reduce the risk of stroke and heart disease.
9. Autism - a male disease
Many people wonder why boys are more likely to be born with autism than girls. Scientists give two answers to this question.
First, men have one X chromosome. It is likely that this fact makes them more vulnerable to birth defects, since damaged genes do not have protection that can cover or repair them.
The second rationale is called anatomical. Researchers believe that there are differences between the models of “internal communications” in the brain between men and women.
The brain of the stronger sex has stronger local connections within the hemispheres, but its external connections between the hemispheres are weaker.
8. Fat deposits
In the male body, the visceral type of fat predominates, it is deposited deep in the body, between organs, mainly in the intestinal region.
As a result, a man has a “pregnant tummy”. This type of body fat is quite complex, it is difficult to get rid of it.
In the female body, fat is deposited immediately under the skin, getting rid of it is much easier, it also harms the internal organs less.
Problems such as excessive sweating, shortness of breath, pain in the heart area in overweight women are less likely than in gentlemen.
7. Color perception
In life, situations often occur when men and women argue about the perception of a particular color. Some members of the stronger sex seriously believe that ladies simply know more names for colors than they do. But this is not so.
Researchers found that the male and female bodies actually perceive colors differently. The reason for this is that 20 percent of the information comes from the outside world and it depends on the structure of the eyes. Processing 80 percent depends on the activity of the nervous system and other characteristics of the body.
Different methods of processing information regarding color are affected by the level of male hormone testosterone, since the higher it is, the more difficult the connection between nerve endings.
6. Eyelash length
Many representatives of the fair sex note that their second half-men have eyelashes much thicker and longer than their own. What is the reason for this, not everyone knows.
The thing is again in the male hormone - testosterone, it is he who makes the hairs stronger, more elastic and longer. In addition, men do not use makeup, allowing eyelashes to remain in a natural state.
Women regularly paint their eyelids with shadows, apply mascara, cosmetic products to the cilia, even if the most expensive does not improve the health of hairs, they need to be given rest.
5. Causes of death
Scientists have found that men have more causes for death.
They are able to die from any type of disease, except those that are characteristic of the female body, that is, breast cancer, various ailments of the reproductive female reproductive system, including those that cause the development of tumors.
4. Blood Composition
Men and women have not only different blood composition, but also its volume and density. Also, representatives of the stronger sex in the blood have more red blood cells, which allow them to easily cope with physical exertion, the hormone testosterone, which gives men endurance.
In female blood there is more hormone - serotonin, which creates a good mood for ladies, gives joy and reverie.
3. IQ level
It is believed that in men the level of intelligence is higher than in women. This hypothesis is quite common in society today.
The development of intelligence is influenced by the structure of the brain, hormones, parenting, genes, level of education.
Some scientists suggest that a man’s brain weighs about 100-150 grams more than a woman’s brain, which determines the speed of information processing.
Representatives of the stronger sex cope with some tasks faster.
2. Face shape
Having looked at the shape of a person’s face, most of us immediately correctly guesses his gender, despite the hairstyle. We can do this, since the face shape in men and women has differences.
For example, in the fair sex, the forehead has a rounded shape, clear contours, in men, the forehead is higher and wider.
Also, in men and women, the hairline, the base of the nose bridge (in men is larger), the thickness of the lips, the structure of the chin are different.
1. Finger Length
In most men, the ring finger is longer than the index finger, and in women, on the contrary, or they have the same length. Scientists have found that the difference in the proportions of the ring finger and index finger is determined by the ratio of male and female hormones (androgens and estrogens).
Studies of mouse embryos have helped to clarify this feature. Scientists observed them during the development period from 13 to 17 days, if at that time the amount of female hormone in the body of the mouse mouse prevailed, then the fingers of her cub developed according to the female type, if the male hormone, then the fingers developed according to the male type.
