Why women can slower aging men? The study showed that estrogen protects cells from wear and tear.
It is well known that women live longer than men, and the answer to this phenomenon may be protective effect that the female hormone estrogen has on the chromosome. One of the best indicators of life expectancy is the length of telomeres – the end parts of chromosomes. The telomeres of women are longer than men, they longer retain this length. And now researchers from the University of California in San Francisco suggested that the female hormone estrogen enhances the activity of the enzyme that extends telomeres, thereby increasing life expectancy.
Magicforum recalls that on average, women live 5% longer than men all over the world, though the difference in life expectancy between the sexes varies from country to country. In Russia, this difference is more than 10 years, and in Scandinavia only one or two years. Experts believe that life expectancy is affected by external factors. For example, men are more likely to drink alcohol and smoke, because of which they face an increased risk of heart disease. One recent study showed that the difference between men and women in life expectancy may disappear by 2032 due to a reduction in the number of smokers and alcoholics.
And now a new study shows that these differences can be encoded in the genes of men and women. Our DNA is encoded on 23 pairs of chromosomes and telomeres. Without telomeres, the cells begin to age quickly and die, so their length is especially important. Reduce this length by such factors as stress, health problems and bad habits. Researchers from California have suggested that one of the factors that protects the length of telomeres, is the female hormone estrogen. (READ MORE)
