Effect Evaluation of Iraqi Date Palm Pollen on Sex Hormones Level of Male Local Rabbits

This study investigates the biochemical and histological effects of Iraqi date palm pollen (IDPP) (Phoenix dactylifera L. variety El-Ghannmi Ahmar) on the levels of sex hormones in the sera of adult male rabbits. Twenty eight adult male rabbits were used, divided into 4 groups (C, G1, G2 and G3).C is a control group, whileG1, G2 and G3 were orally treated with 30, 60 and 90 mg/kg/day of oily IDPP for 4 weeks, respectively. The results indicated that the level of Luteinizing hormone (LH) was significantly (p≤0.05) increased in G1 and G2, while there was no significant change in G3 as compared with C. The level of Follicular Stimulating hormone (FSH) was significantly (p≤0.05) increased in G2, as compared with C and not significant in G1 and G3.In addition, no significant change in prolactin levels, while the level of testosterone significantly (p≤0.05) improved in all groups. The effect of IDPP on testicular of treated male rabbits was studied histologically. The histological study indicated that IDPP increased the active spermatogenesis with significant rise in the number of mature sperms in G1, G2 and G3 as compared with C. It could be concluded that IDPP improved fertility by boost production of testosterone and increase the spermatogenesis at seminal tubules by increasing the primary and secondary spermatocytes.
