For ages, a lot of folks believed that masturbation could make you go blind, become mentally ill, or kill the neighborhood kittens.

年来，很人都认为手淫会让你失明、患精神病或杀死邻居家的小猫。

One study found that in males, components of the immune system are activated during masturbation, increasing the number of white blood cells in the bloodstream.

一研究发现，在男性中，免疫系统的组成部分在手淫期间被激活， 从而增加中白细胞的数量。
