Date Palm (Phoenix dactylifera) as a Natural Test Booster and Ergogenic

A very recent study (Saddiq. 2010) published in the Journal of the International Society for Horticultural Science found that the seeds of Phoenix dactylifera can raise testosterone, norepenephrine (NE), dopamine (DA) and GABA levels and may counteract the negative effect of prednisolone administration in rats.

[...] the daily oral administration of pits of date palm caused the maximal increase in NE, DA and GABA content that was found in the brain stem after 2 weeks. The daily oral administration of methylprednisolone caused a decrease in NE, DA and GABA content found in the brain stem after 2 weeks. Moreover, the daily oral administration of pits of date palm and methylprednisolone caused an increase in NE content found in the brain stem after 2 weeks. The daily oral administration of pits of date palm and methylprednisolone caused a significant increase in testosterone level in serum blood of male albino rats.

While all this sounds promising, further studies would have to clarify whether it needs the cortisol-like effects of prednisone for the testosterone-boosting effect of the date seeds to take place or whether taking adequate amounts of pits of date palm would provoke similar (or even superior) increases in testosterone in rats and, most importantly, in men. Be that as it may, even the increase in neurotransmitters (NE, DA, GABA) certainly could provide real-world benefits for athletes, as well as people suffering from fatigue.
