Sexual arousal in sexually sluggish old male rats after oral administration of Eurycoma longifolia.J Basic Clin Physiol Pharmacol. 2004. Ang HH, Lee K. School of Pharmaceutical Sciences, University Science Malaysia, Minden, Penang, Malaysia.
The objective of this study is to evaluate sexual arousal in sexually sluggish old male rats, 24 months old and retired breeders, receiving 200, 400, or 800 mg/kg of various fractions of tongkat ali, twice daily, for 10 days. Control rats received 3 ml/kg of normal saline. The aphrodisiac effect was monitored by the act of yawning and stretching because yawning, either alone or associated with stretching, is considered an ancestral vestige surviving throughout evolution that promotes sexual arousal. The results showed that 800 mg/kg of tongkat ali increased yawning by 50% and stretching by 16% in sexually sluggish old male rats, by 676-719% and 31-336%, respectively, in sexually active male rats, and by 22 to 44% and 75 to 100%, respectively, in middle aged, 9 months old and retired breeders. We conclude that the results of this study support the folk use of this plant as an aphrodisiac.
Eurycoma longifolia enhances sexual motivation in middle-aged male mice.
J Basic Clin Physiol Pharmacol. 2003.
Tongkat Ali was investigated for sexual motivation activity in adult, middle-aged male mice and in retired breeders. Each mouse received 500 mg/kg of one of 4 fractions of tongkat ali : chloroform, methanol, butanol, and water, whereas the mice in the control and yohimbine groups received 3 ml/kg of normal saline and 30 mg/kg of yohimbine daily respectively for 10 days. Our study showed that this potent herb continues to enhance sexual motivation in adult, middle-aged male mice and in retired breeders.

The effects of tongkat ali were studied on the sexual qualities of middle aged male rats after dosing them with 0.5 g/kg of various fractions of tongkat ali whilst the control group received 3 ml/kg of normal saline daily for 12 weeks. Results showed than tongkat ali enhanced the sexual qualities of the middle aged male rats by decreasing their hesitation time as compared to controls.

Effect of Eurycoma longifolia Jack on orientation activities in middle-aged male rats.
Fundam Clin Pharmacol. 2002.
Results showed that subjects treated with tongkat ali increased orientation activities towards the receptive females (anogenital sniffing, licking and mounting), increased genital grooming towards themselves and restricted movements to a particular area of the cage but decreased interest in the external environment (climbing, raring, exploration) as compared with the controls during the investigation period. In conclusion, this study gives further evidences that different fractions of tongkat ali modified the orientation activities of the middle-aged male rats.
