Résumé
Traditional medicine provides strong guidance for scientific experiments involving plant products used by the Brazilian people. The species "cipó-cravo" (Tynnanthus fasciculatus) is a plant commonly used either to combat indigestion and stomachaches, or as a general stimulant and aphrodisiac. In this study, the effects of "cipó-cravo" infusion were investigated within the testicular parenchyma of adult Wistar rats. Rats were divided into 3 groups: a control (distilled water) and two treated groups, which received the plant infusion (100 and 200mg/animal/day). The 200mg dose promoted a significant increase of the testicular parenchyma weight and of the volume and total length of the seminiferous tubules, as well as in total daily sperm production and sperm production per gram of testis.
