Free serum testosterone level in male rats treated with tribulus alatus extracts

Abstract

Objective: The present study was undertaken to investigate the effect of Tribulus alatus extracts on free serum testosterone in male rats. Materials and Methods: Free serum testosterone level was measured in male rats treated with alcoholic extracts of the aerial part without fruits, fruits of Tribulus alatus and their fractions. Results: All tested extracts showed significant increase in the level of free serum testosterone when compared to that of corresponding control, p < 0.05. Statistical comparison of all groups revealed that the maximum level was found in groups treated with chloroformic and ethanolic fractions of fruits extract. Conclusion: Tribulus alatus extract appears to possess aphrodisiac activity due to its androgen increasing property.
