Ok, maybe it doesn’t exactly KILL — but new research in Japan suggests that spermies can shorten the lifespan: “female mice produced by using genetic material from two mothers but no father live significantly longer than mice with the normal mix of maternal and paternal genes. Their findings provide the first evidence that sperm genes may have a detrimental effect on lifespan in mammals“.
So in addition to being icky, sperm’s kinda harmful for your health. Wow, what implications does this hold for the future of human reproduction? Maybe by 2050 we’ll just do away with men altogether, and Amazonian ladies will be charged with procreating a new breed of bionic superhuman supermodels. Another good argument for having two moms.
