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<0.000 1) 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<0.000 1) 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.
