Abstract

This study was conducted to determine the role of Phoenix dactyliferapollen grains suspension in improving reproductive efficiency of white male rats. In thisexperiment 40 adult male rats were divided randomly into five equal groups and by following oral administration:thefirst group was given Phoenixd.pollen grains suspension with concentration 18 mg/kg body weight daily, the second group was given 54 mg/kg, the third group was given 108 mg/kg and fourth group 216 mg/kg body weight, and thelast group which represented a control group administrated distilled water only, the administration continued for 40 consecutive days. The effect of Phoenixd. pollen grains in reproductive efficiency was evaluated depending on some parameters such as: weights of (testes, epididymes, seminal vesicle and prostate gland), Some testes parameters of epididymis sperms (sperms concentration, percentage of both sperms motility and viability and percentage of normal sperms).and measuring of some hormonal levels which affect on spermatogenesis like [Luteinizing hormone(LH), Follicle stimulating hormone(FSH) and Testosterone hormone(T)]. The results showed a significant increase (P<0.05) in genital organs weights especially in the third group compared with a control group .Also there wasa significant increase (P<0.05) in sperms concentration and motility in the second and third groups as compared with the control group, there was a significant increase in the percentage of sperms viability in the third group compared with a control group ,while there was significant decrease (P<0.05) in this groups in LH hormone level compared with control group incrementally down from the first group until the third group, while there was a significant increase (P<0.05) in FSH in second and thirdgroups and significant increase in testosterone levels in all treated groups compared with a control group.It's concluded that oral administration of Phoenixd.pollen grains suspension led to positive improvement in some sides of reproductive efficiency of white male rats (P
