The sex difference in lifespan is likely to be linked to secondary sexual characteristics. It is linked to the traits that are controlled by sex hormones — something that is established in puberty. In males, one of the main determinants of secondary sexual characteristics is testicular hormones: testosterone and dihydrotestosterone. And there is a hypothesis that testosterone is what is driving the shorter lifespan in men.
