Anti-androgenic activity of Leptadenia hastata (Pers.) Decne: competitive effect of the aqueous extracts of the plant and the testosterone propionate on castrated immature rats. The anti-androgenic activity and the evaluation of competitiveness between the extracts of Leptadenia hastata and the testosterone propionate (TP) were studied on Wistar immature castrated rats. The first group received only 0.04; 0.4; 4; 40; 400 and 1,000 µg.kg-1 of TP and the second group received simultaneously these different doses of TP and 200 mg.kg-1 of L. hastata. The various treatments showed a significant increase (p < 0.05) of the weight of androgeno-dependent organs and the level of plasmatic testosterone. At low dosis of TP, the dosis of 200 mg.kg-1 of L. hastata inhibited TP effects, whereas at high doses of TP L. hastata extracts potentiated TP effects. In conclusion, the anti-androgenic effect of the extract of L. hastata is expressed when the TP amounts are weak.
