| 1 | Effect of Lepidium meyenii (maca) roots on spermatogenesis of male rats显示文摘Aim: To determine the effect of oral administration of an aqueous extract from the roots of Lepidium meyenii (maca)on spermatogenesis in adult male rats. 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). | Gustavo F.Gonzales Ana Ruiz Carla Gonzales León Villegas Amanda Cordova | 2001 | Asian Journal of Andrology2001，3，3： | 22 |
| 2 | Effect of two different extracts of red maca in male rats with testosterone-induced prostatic hyperplasia显示文摘瞄准:在更男的 ats 决定红 maca 的二篇不同摘录的效果。方法:Prostatic 增生与睾丸激素 enanthate (TE ) 在雄的老鼠被导致。Thestudy 包括了六个组:一个控制组(组 1 ),与 TE (组 2 )对待的一个组,与 TE 对待的二个组和红 maca 的水的摘录(组织 3 和 4 ),一个组对待红 maca (组 5 )的 withhydroalcoholic 摘录,一个组与 finasteride 对待( 0.1 mg , group6 )。在沸腾的时间的长度上的水的摘录依赖者的差别,是否为 2 个 or3 小时,为组, 3 和 4 被估计。红 maca 的摘录包含了 0.1 mg ofbenzylglucosinolate。此后,在红 maca 摘录的 benzylglucosinolates (0.02-0.08 mg ) 的不同剂量的剂量反应效果被估计。结果:前列腺重量在与红 maca 的水的摘录在沸腾的 2 和 3 个小时以后准备了的 freeze-dried 对待的老鼠是类似的。红 maca 的 Freeze-dried 水的摘录,红 maca 和 finasteride 的水疗院酒鬼摘录与职业人员静电干扰增生在老鼠减少了前列腺重量。没有差别在从水的摘录或红 maca 的水疗院酒鬼摘录获得的数据之间被观察。前列腺重量的剂量依赖者减小随红 macaextracts 的 benzylglucosinolates 的剂量的增加被观察。结论:现在的学习在 prostatichyperplasia 被 TE 在导致了的雄的老鼠给那个水疗院酒鬼或红 macacontaining 的水的摘录看了 benzylglucosinolate 罐头还原剂前列腺尺寸的 0.1 mg。 | Gustavo F.

| 3 | Effect of alcoholic extract of Lepidium meyenii (Maca) on testicular function in male rats显示文摘Aim: To evaluate the effect of the alcoholic extract of Lepidium meyenii (Maca) on the spermatogenesisin male rats. Methods: In Holtzman rats, Maca alcoholic extract (5 %) was given by oral route at doses of 48 mg/day or 96 mg/day for 7 days, 14 days and 21 days. Testicular function was assessed by measurements of lengths of different stages of seminiferous epithelia and by epididymal sperm count. Results: Ethanolic extract of Maca increased the length of stages IX-XI of seminiferous epithelium at treatment day 7, day 14 and day 21. Progression of spermatogenesis was evident only after day 21 when lengths of stages XII-XIV of seminiferous epithelium were increased; at day 7 and day 14, no important change in spermatogenesis was observed. Epididymal sperm count was increased with 48 mg/day at all times. With 96 mg/day an increase in sperm count was observed at day 7, but it was reduced at day 14 and day 21 of treatment. Serum testosterone levels were not affected. Conclusion: The alcoholic extract of Maca activates onset ant progression of spermatogenesis at 48 mg/day or 96 mg/day in rats. | Gustavo F.
