In order to study the effect of magnetic action on the rabbit tests, we fed the rabbit with magnetized water and embedded the small magnetic disc at "guanyuan point". Five months later, the total sperm number as well as the sperm number per 100 mg in epididymal tail of the experimental group significantly increased than those of the control group. The observation by light microscope and scanning electron microscope showed more increased spermatogone, spermatoblast and sperm in the experimental group than in the control. This study indicates that drinking magnetized water and embedding magnet disc at "guanyuan point" have a spermatogenic effect
