Research into 1,153 elderly men at the University of Sweden discovered the individuals who had lost piece of their Y chromosome kicked the bucket generally speaking 5.5 years sooner than the individuals who had not.
Ladies live by and large 7.5 years longer than men in Europe and the explanations for this are not completely known.
Tumor Research said the study was “captivating”.
Researchers evaluated what number of platelets had age-related loss of the Y chromosome (LOY) through blood tests in the men, matured somewhere around 70 and 84.
Men with a “noteworthy sum” of misfortune kicked the bucket prior, said scientists. LOY was connected with general danger of death in 637 out of the gathering of men and danger of death because of non-blood related disease in 132 of the cases.
Scientists said the relationship in the middle of LOY and early passing was noteworthy when the results were balanced for age and other wellbeing conditions.
Ladies don’t have the Y chromosome, yet have two Xs.
The co creator of the study, Jan Dumanski from Uppsala University in Sweden, said: “Numerous individuals think the Y chromosome just contains qualities included in sex determination and sperm generation.
“Actually, these qualities have other paramount capacities, for example, conceivably assuming a part in avoiding tumors.”
The study said Y chromosome qualities were not communicated when LOY happened, significance its potential part in tumor anticipation could be lessened.
It said LOY in platelets was connected with numerous diverse growths, including those outside the blood framework.
Scientists said this could be on the grounds that Y chromosome qualities empowered platelets to help with immuno-reconnaissance, where the invulnerable framework recognized and murdered tumor cells to forestall growth.
The discovering means blood tests taking a gander at the state of the Y chromosome could help anticipate a man’s danger of malignancy, say the creators.
Head of wellbeing data at Cancer Research Dr Julie Sharp said: “This is a fascinating hypothesis however more research is required to create whether loss of the Y chromosome truly could be an indicator of malignancy danger.
“While a man’s danger of disease does increment with age, there are things all men can do to stack the chances to support them, for example, not smoking, keeping up a sound weight, consuming strongly and eliminating liquor.”
