Objective: To estimate the effects of the water extract of dates palm (phoenix dactylifera) (DWE) on sperm quality parameters, testosterone level and serum antioxidants activities of New Zealand rabbits under heat stress. Methods: A total of 30 bucks of New Zealand White rabbits were randomly divided into three equal groups as follows: Group 1 was treated as control group and fed on balanced commercial ration. Groups 2 and 3 were treated with 10 and 20 mL of dates extract substituting water in the early morning before watering and fed on balanced commercial ration. This schedule was performed daily for 5 days/week, for an experimental period of 5 weeks. Fertility parameters such as reaction time, potential of hydrogen ion (pH), mass motility, individual progressive motility %, percentage of live sperm and abnormal sperm (%) were measured. Blood serum testosterone level, serum glutathione reduced, nitric oxide, ascorbic acid and malondialdehyde were also determined. Results: The daily oral administration of 10 mL DWE significantly increased the pH, the mass motility and individual progressive motility % compared to the control group. Although, the consumption of 20 mL DWE significantly (P<0.0001) increased the live sperm% and decreased the abnormal sperm % compared to the other two treatments. The administration of date extracts (10 and 20 mL) had significantly (P<0.0001) decreased nitric oxide and glutathione reduced levels compared to the control. On the other hand, it increased significantly the lipid peroxidation, ascorbic acid and testosterone level compared to the control. Conclusions:The aqueous extract of date palm (10-20 mL) could enhance the rabbit bucks fertility and its health performance.

Background: Dopamine has been known to facilitate male sexual function. Methods: The effect of aqueous extract (140 mg/kg) of phoenix dactylifera date palm pollen on sexual behavior and determining of dopamine transmission in the nucleus accumbens was studied in male rats using in vivo microdialysis. Results: Releasing of dopamine increased significantly in the nucleus accumbens when a receptive female was introduced behind a screen (p 0.001). During copulation, dopamine increased markedly in control and treated rats. phoenix dactylifera Date Palm Pollen enhanced the orientation of males towards females by increasing mounting and ano-genital investigatory behavior. Improving of sexual behavior and dopamine release was higher in treated rats in comparison with control (p 0.001). Conclusion: These results indicate a neurochemical basis for interaction between dopaminergic agents and male sexual behavior. Therefore, phoenix dactylifera Date Palm Pollen seems to act as a dopamine agonist and to cure male infertility. It can be used as an aphrodisiac that leads to further increases in dopamine release.

Our overall knowledge of the medicinal uses of plants suggests that natural compounds could be useful in the treatment of cutaneous fungal infections in tropical regions. Furthermore, the possibilities of treatment using plant extracts may be even broader than is already known when one considers plants that have not been extensively studied in this context, such as the regional species phoenix dactylifera and Ziziphus spina-christi. This study compared the antimicrobial activity of phoenix dactylifera and Ziziphus spina-christi extracts in terms of their biochemical and molecular effects on Candida albicans (ATCC CA 10231). These effects included altered levels of intracellular sterols, changes in the permeability of the cell membrane, and changes in the TEF1: QRTTEF1, CaERG1: ERG1, CdERG12: CdERG1, and ERG25: ERG25 genes. Scanning electron microscopy (SEM) was used to identify morphological characteristics, and energy-dispersive X-ray spectroscopy (EDAX) analyses were conducted. In treated samples, the SEM and EDAX analyses showed cell cavities and shrinkage of the cell wall, and the number of cells was reduced to only a few abnormal cells as compared with that in the untreated samples. Yttrium was detected in the cells treated with Z. spina-christi, and high levels of osmium were detected in the cells treated with P. dactylifera. Compared with control cells, cells exposed to the concentration 150 μl/ml of Z. spina-christi extract had an average sterol concentration that was nearly 3 times higher, while the concentration was 5.5 times higher for cells treated with the 150 μl/ml of P. dactylifera extract. The ethanol extracts affected the permeability of C. albicans cell membrane. Gene sequencing showed gaps and mismatches in the ERG1, ERG12, and ERG25 genes after treatment with P. dactylifera and Z. spina-christi extracts compared with that in the controls. The results were highly significant (p ≤ 0.01). We conclude that the ethanol extracts of P. dactylifera and Z

phoenix, a very beautiful and popular image in China,like dragon, is an imagined and legendary animal existing only in people's mind. It is such an important component of Chinese culture that we can see a sort of phenomenon called phoenix phenomenon comes into being in Chinese culture, which deserves efforts to elaborate and whose origin is worth probing. As the totem worshipped by the ancient Chu people, phoenix also displays the basic features of Chinese culture: integratedness and inclusiveness.

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 phytochemic
