Methods: Male rats received an aqueous extract of the root (66.7 mg in one mL) twice a day for 14 consecutive days. Results: Treatment with Lepidium meyenii resulted in an increase in the weights of testis and epididymis but not the seminal vesicle weight. The length and frequency of stages IX-XIV seminiferous tubules, where mitosis occurred, were increased and stages Ⅰ-Ⅵ were reduced in rats treated with Lepidium meyenii. Conclusion: The Lepidium meyenii root invigorates spermatogenesis in male rats by acting on its initial stages (IX-XIV). 关 键 词：雄性老鼠 生殖系统 精子发生 透照法
