Effects of catuaba cristal？ on the testis of wistar rats

the aim of this study was to evaluate the possible beneficial effects of catuaba cristal？ (cc), an alcoholic drink made from wine and erythroxylum catuaba ar. cam on testis. wistar rats either received cc solution (n=8) or water (n=9). results showed significant body weight reduction within the cc group, although, no weight changes were observed for liver, kidney, testis, epididymis, seminal vesicle and prostate. the volumetric proportion and volume of interstitial tissue and lymphatic space were reduced in the treated group. in the cc group, although the nuclear volume of leydig cells (lc) decreased, the number of lc per testis increased. these results suggested that cc had no beneficial effect on spermatogenesis of wistar rats.
