Human supercentenarians share at least one thing in common–over 95 percent are women. Scientists have long observed differences between the sexes when it comes to aging, but there is no clear explanation for why females live longer.

It’s known that estrogen has direct effects on stem cell populations in female mice, from increasing the number of blood stem cells (which is very helpful during pregnancy) to enhancing the regenerative capacity of brain stem cells at the height of estrus. Whether these changes have a direct impact on lifespan is what’s yet to be explored.

“It is likely that sex plays a role in defining both lifespan and healthspan, and the effects of sex may not be identical for these two variables,” the authors write. “As the search continues for ways to ameliorate the aging process and maintain the regenerative capacity of stem cells, let us not forget one of the most effective aging modifiers: sex.”
