Women begin to age earlier than men | capital Cities

The study shows that signs of aging appear earlier in women’s organs, but develop more slowly than men’s

In an effort to understand how aging works and find ways to slow it down, researchers around the world are looking into the nitty-gritty of how the human body works. One of the latest news on the subject was released this week: Danish and Spanish scientists have discovered that women start showing the first signs of aging much earlier, around 19, but that time passes more gradually for them.

As for men, changes appear around the age of forty, but they are developing rapidly. The study was published in preprint, meaning it has not yet been peer-reviewed by the scientific community.

Between 1970 and 2018, 33 million biopsy reports from 4.9 million people were analyzed for cell markers to check organ aging. Experts believe that the big difference between the sexes is menopause.

Physiology professor Manuel Tina Semper, of the University of Córdoba, Spain, explains in an interview with New Scientist. Among men, the decline in androgen levels is gradual, leading to completely different consequences, according to experts.

However, the scientists caution that the scan has a major limitation: All participants sought medical attention and were referred for a biopsy before the data could be analyzed. It is known that men, traditionally, tended to seek a doctor only when symptoms were already advanced, unlike women. Thus, the results may have been affected by a sample of older men.

Each member ages in its own time

The same study shows that not all body tissues age at the same time, confirming the findings of a Spanish survey published in the scientific journal Proceedings of the Real Society B.

Scientists have discovered that cells make many copies of themselves throughout life. In the process, information is lost. Just imagine a paper that has been copied many times – the ink tends to get weaker and weaker and eventually it becomes difficult to read what is written.

With the loss of information, the chromosomes become smaller, which reduces the telomeres (the cap of the chromosome, like the hard part of a shoelace, which limits its size). One of the signs of biological aging is precisely the shortening of telomeres, that is, the more tissues are copied, the faster they age.
