Well I want eternal youth? So many children now!

Scientists from Simon Fraser University in Canada through the study found that the number of children or aging can affect the female body, research published in the international journal PLoS ONE.

Article, the researchers found, can give birth to more children surviving female body contains long telomeres, telomeres protect the ends of the ends of the DNA, but also an indicator of body cell aging, longer telomeres for At the same time it is also essential for cell replication and the body is directly related to longevity.

In this paper, the researchers on two adjacent local rural communities in Guatemala 75 women carried out relevant research, investigated the association of participants and the number of children born between telomere length, the researchers through the saliva samples and the chamber within wipes analysis, separated by 13 years in the two time points in telomere length were measured participants, this study is the first analysis of the number of direct relevance children between telomere shortening and body.

In this paper, a speculation denied before, namely that the more the number of children women would accelerate biological aging trajectory Nepomnaschy researchers said, but we found that telomere shortening rate of children in female organism more slowly This may depend on the dramatic increase in women during pregnancy produced due to estrogen, and estrogen can be used as a potential antioxidant to protect cells from telomere shortening.

The researchers also explained that participants in the social environment may also affect their fertility association between effectiveness and the aging process, the researchers tracked in the article are from the group of women with a natural fertility, that fertility more mother often received from relatives and friends more social support, a lot of support will increase female body's energy metabolism, thus can maintain the body's tissues, and thus slow down the aging body; of course researchers also hope that through the latter part of a large number of studies are needed to elucidate the molecular mechanisms behind this phenomenon.
