Surprising Biological Differences between Men & Women

relationships-love-couple-hug

Everyone knows that men and women differ from each other. Many of these differences stem from the biology of people (of course, we are not talking about the most obvious features).

1. Genetic protection

Most of the babies that are born with birth defects are men. If a woman demonstrates the gene defect, she will still have another copy of the X chromosome.

2. The diameter of veins

Men’s veins are usually larger.

3. Autism is a male disease

Men are 4 times more likely to be autistic than women.

4. Different foreheads

Women tend to have higher foreheads. Men’s foreheads are more sloping as a rule.

5. Fat deposits

In men, fat accumulates between the body organs. In women, it forms a ring around the stomach. That is why liposuction is performed much easier in women.

6. The length of eyelashes

This may be unexpected, but men usually have longer lashes.

7. The length of fingers

The index finger of a woman’s hand is usually longer than the ring finger. In men, it is vice versa.

8. Mitochondrial diseases

Only women can pass mitochondrial diseases to their offspring.

9. Stutterers

Men are from 3 to 10 times more likely to stutter.

10. Hearing loss

Although both sexes lose their hearing equally often, men tend to stop hearing high-pitched sounds, while women fail to hear low sounds.

11. Color perception

Women are significantly better at distinguishing the shades of different colors than men.

12. Blood circulation

The blood flow is distributed more evenly in the male body. In women, it is centered around the major organs and the pelvic area.

13. The performance of liver

There are about 1,000 genes associated with liver, which are different in men and women. That is why both sexes “digest” alcohol and drugs at different speeds.

14. The shape of the face

Women tend to have a wider face than men.

15. The shape of the skull

The external occipital protuberance (a lump on the back of the skull) is bigger in men than in women.

16. Jaws

The jawbone is heavier in men than in women.

17. IQ

Some studies have shown that men have a greater standard IQ deviation. Media have distributed this information at once, explaining why there are more mentally disturbed people, people with disabilities, as well as geniuses among men.

18. Breathing

Women tend to get most of their energy from aerobic respiration, while men rely on anaerobic respiration.

19. The form of eye sockets

The upper edge of the eye socket in women is much sharper than that of men.

20. Vision

Women have a more developed peripheral vision than men, while men tend to have better cursory vision. It is believed that this feature has evolutionary origin (hunters vs. collectors).

21. Cardiac symptoms

During heart attacks, men experience “classic” symptoms, such as chest pain and pain in the jaw. Symptoms in women can be quite various.

22. The composition of blood

Female blood contains more water and about 20% less erythrocytes.

23. Mental activity features

Although female brain is better suited for many other tasks, male brain is better focused on exploring the surrounding area.

24. Diseases

Women tend to more easily develop the diseases of the musculoskeletal system, especially during pregnancy.

25. Death causes

Men die more often than women of almost all diseases, while women die of breast cancer, the female reproductive system disorders and benign tumors.
