昆明种健康成年（4—5月）雄性小鼠17只，随机分为给药组10只和对照组7只。用五味子水煎剂为给药组小鼠灌胃30天，取睾丸作常规石蜡切片，组织学观察；并用体视学方法测量睾丸曲细精管直径。结果显示：五味子使睾丸重量增加了57．1％，使由细精管直径增加了41％，并且光镜下生精细胞的层数及精子的数量有所增加。以上结果提示五味子有促进精子发生的作用。
Eighteen healthy male Kunming male mice (April-May) were randomly divided into a drug-administered group and a control group. The mice in the administration group were given intragastric administration with Schisandra decoction for 30 days. The testes were subjected to routine paraffin sections and histological observations were made. The diameters of the seminiferous tubules of the testicles were measured by stereological methods. The results showed that: Schisandra increased testis weight by 57.1%, increased the diameter of the spermatic duct by 41%, and the number of spermatogenic cells and the number of spermatozoa increased under light microscope. The above results suggest that Schisandra has the effect of promoting spermatogenesis.
