Telomeres are DNA fragments whose length is very long at birth and then becomes shorter and is regarded as a sign of aging  After analyzing data over the years, the researchers found that the average telomere length of women who had at least one child was 4 2% shorter than that of infertile women  This percentage is equivalent to 11 years of cell aging, outpacing the effects of smoking and obesity on cell aging
As a result, it has been suggested that having children will speed up the aging of women
