This is a good news for most of the females excluding the ones who love their husbands more than themselves. Women life expectancy is higher than men due to loss ‘Y’ chromosomes in Men. Compared with women, men have a shorter life expectancy. The US Centers for Disease Control and Prevention estimate that women live an average of 5 years longer than men. Now, a new study suggests this disparity may be down to a loss of the Y chromosome in blood cells, prompting men to have a shorter life span and higher mortality from cancer.
The researchers explain that the Y chromosome is only present in men, and that until now, the genes on this chromosome were mostly associated with sex determination and sperm production. After studying the group of men for many years, the researchers found that the most common genetic alteration was a loss of the Y chromosome (LOY) in a proportion of the white blood cells.
For the study, researchers analyzed the DNA in blood samples from a group of more than 1,600 elderly men. During the study, they discovered that the most common genetic alteration was a loss of the Y chromosome in a proportion of the White Blood Cells (WBCs). According to the researchers, the Y chromosome has genes that are manifested by tissues and body organs that play a vital role in understanding the composition of male genome and helps them in improving their survival skills.
The figures from worldlifeexpectancy.com as on 15 may 2014 suggests that Women in US would live for an average of 81.17 years. In Hawaii women life expectancy is highest at of 84.83 years and the women life expectancy for the women living in West Virginia is 78.09 years that is the lowest.
While most of the death are a result of cardiac arrest or problems related to heart it is followed by Cancer,Stroke,Lung problems,Accidents. While Parkinsons, Homicide and Hypertension are amongst the causes which are least responsible.
Women life expectancy is thus not surprising only in US. Compared with men, Women life expectancy is higher. The US Centers for Disease Control and Prevention estimate that women live an average of 5 years longer than men. Now, a new study suggests this disparity may be down to a loss of the Y chromosome in blood cells, prompting men to have a shorter life span and higher mortality from cancer.
