Abstract:

Aim of study: Ancient literature alluded to the use of a number of plants/preparations as sex enhancer. One of such botanicals is Phoenix dactylifera in which the pollen grain has been acclaimed to be used as an aphrodisiac. However, the validity has not been scientifically tested. Dopamine is known to facilitate male sexual function. Therefore, the present study was undertaken to evaluate the effect of aqueous extract of Phoenix dactylifera pollen on the sexual behavior of male rats and to measure of serum Estradiol and Testostrone. Also, dopamine transmission in the nucleus accumbence (NAc) was studied in male rats using in vivo microdialysis. Methods and Materials: sixty male rats were randomized into 6 groups (A-F). Group A received 0.2 ml of Normal Saline mixed with Dimethyl Sulphate (DMSO), while groups B-F were injected same volume containing 35 mg/kg, 70 mg/kg, 105 mg/kg, 140 mg/kg and 350 mg/kg of DPP extract, respectively. Sexual behavioral parameters including mounting, intromission and ejaculation frequencies and latencies were recorded in male rats one hour after injection of extract by mating with a receptive female (1:1). The male serum testosterone and estradiol concentrations were also determined. Results: All doses stimulated male sexual behavior. Extract significantly increased mount, ejaculation, intromission frequencies and ejaculation latency in comparison to controlled ones (p < 0.001). Mount and intromission latencies significantly reduced (p < 0.001). Maximum effect was observed in dose 140 mg/kg. This extract was found to enhance Testestrone, Estradiol and the orientation of males toward female ones by increasing mounting and ano-genital investigatory behavior. Conclusions: Data from this study identified that the aqueous extract of Phoenix dactylifera pollen grain enhanced sexual behaviour in male rats. The improved sexual appetitive behaviour in male rats may be attributed, to the alkaloids, saponins, and or flavonoids since these phytochemicals has engorgement, androgen enhancing. Also, our findings support the traditional use of this plant as
