Aphrodisiac evaluation in non‐copulator male rats after chronic administration of Eurycoma longifolia Jack*

The aphrodisiac effect of Eurycoma longifolia Jack (0.5 g/kg) was evaluated in noncopulator male rats using an electrical cage. Fractions of E. longifolia Jack decreased the hesitation time of noncopulator male rats, throughout the investigation period. Furthermore, it possessed a transient increase in the percentage of the male rats responding to the right choice, more than 50% of the male rats scored ‘right choice’ after 3 weeks post‐treatment and the effect became more prominent after 8 weeks post‐treatment (only 40–50% of the control male rats responded to the right choice) using the electrical copulation cage. Hence, this study lends further support to the use of the plant by indigenous populations as a traditional medicine for it’s aphrodisiac property.
