How oestrogen makes women live longer.

Oestrogen is the main female sex hormone. It regulates the reproductive cycle and is responsible for many developmental characteristics. It plays a critical role in a woman’s life. Telomeres do too though. They are present in both men and women and are the long repetitive ends of each chromosome. Those ends are similar to bumpers on a car. They are there to protect the important stuff but don’t do much else. The problem is that with every cell division those telomeres shorten until the valuable DNA is exposed and damaged. At that point we start to see signs of ageing like age related diseases.

The longer the telomeres of a person, the longer he or she will live…. For the most part at least… It is a bit more complicated than that and for more info you should check our other article here: Born by middle aged parents you may have a chance to live longer

Women apparently tend to have longer telomeres. They also have oestrogen that activates telomerase. Telomerase is an enzyme that lengthens telomeres. This enzyme tends to also be upregulated. If you add the fact that women tend to deal better than men with ROS (reactive oxygen species) and have “antioxidant” mechanisms, you start to realize why they live longer.

This is probably part of the reason why. Scientists have many more theories and evolution will probably help us find why while genetics will help us find how women live longer. We are the point where we have a few data and we try to understand it. More research will be necessary since all those results i mentioned while true are only present in some studies. Other studies disagree and it’s hard for anyone to give a definite answer. Telomeres while very important, they are probably regulated by more mechanisms and are only part of the longevity equation.

Although it is interesting to investigate such topics. I have linked my sources below for you to read if you are interested. And for more science and tech news make sure to follow Qul Mind.
