原文：

A growing body of research suggests that the XX set of female sex chromosomes (which, along with other chromosomes, carry our DNA) may impact longevity, though it's not clear exactly how. For example, a 2018 study conducted by Dr. Dubal's lab looked at genetically manipulated mice with different combinations of sex chromosomes and reproductive organs. Those with two X chromosomes and ovaries lived longest, followed by mice with two X chromosomes and testes. Mice with XY chromosomes had shorter life spans.

越来越多研究表明，女性的性染色体XX（与其他染色体一起携带着DNA）可能对寿命有影响，但目前尚不清楚具体机制。例如，在2018年杜巴尔实验室的一项研究中，对具有不同性染色体和生殖器官组合的基因改造老鼠进行观察。拥有XX染色体和卵巢的老鼠寿命最长，其次是拥有XX染色体和睾丸的小鼠。拥有XY染色体的老鼠寿命则较短。
