Some people have compared saving someone's life by donating marrow to giving birth, since it creates, or rather extends, a life. One difference is that after bringing a child into the world, it may be ten or twenty years before that child plays a productive part in the world, whereas mature adults given new life through marrow donation can very quickly resume their roles in society.
有人將捐髓救人與生產相提並論，同樣是再造生命、延續生命；不同的是，生下一個孩子，得經過一、二十年孩子才能在社會上發揮功能；捐髓使一個人獲得重生，他可以很快的回到崗位上發揮功能。
