Abstract
It has been reported that Eurycoma longifolia Jack commonly known as Tongkat Ali has gained notoreity as a symbol of man¡¯s ego and strength by the Malaysian men because it increases male virility and sexual prowess during sexual activities. As such, the effects of 200, 400 and 800 mg/kg of butanol, methanol, water and chloroform fractions of E. longifolia Jack were studied on the laevator am muscle in both uncastrated and testosterone-stimulated castrated intact male rats after dosing them for 12 consecutive weeks. Results showed that 800 mg/kg of butanol, methanol, water and chloroform fractions of E. longifolia Jack significantly increased (p<0.05) the leavator am muscle to 58.561.22, 58.23 0.31, 60.21 0.86 and 62.35 0.98 mg/100 g body weight, respectively, when compared with the control (untreated) in the uncastrated intact male rats and 49.23 0.82, 52.23 0.36, 50.21 0.66 and 52.35 0.58 mg/100 g body weight, respectivety, when compared to control (untreated) in the testosterone-stimulated castrated intact male rats. Hence the proandrogenic effect as shown by this study further supported the traditional use of this plant as an aphrodisiac
