The role of date palm pollen grains extract in fertility improving

Abstract

         The impact of the ethanol extract of date palm pollen grains (DPP) was examined in the fertility enhancement of female rats exposed to oxidative stress by sodium nitrite. forty female mature rats assessing 150- 200 g were grouped into five groups. First group were received distilled water save as control group, The second group was administered 100 mg/kg of crude DPP extract, third group received 100 mg/kg of crude DPP extract combined with 100 mg/kg body weight of sodium nitrite, forth group received 100mg/kg B.W of sodium nitrite, while fifth group was drenched 100mg/kg B.W of sodium nitrite for 28 days then 100mg/kg of crude DPP extract for another 14 days. Then we added the same number of mature male rats to determination the ability of DPP extract for fertility enhancement.  the Animals were kept until the parturition occurred then determination the pregnancy index, fertility index, and viability index. The DPP extract caused clear changes in percentage of the parameters of pregnancy, viability and fertility indexes compared to the groups exposed to sodium nitrite, and also following the treatment of animals with DPP extract after exposure to sodium nitrite showed improvement of fertility and pregnancy indexes. The best enhancement activity of DPP extract was clarified in the result of long term treatment (fourth group). Conclusions: The study showed the ability of palm pollen grain extract to improve fertility and protective effects and treatments the harmful effects of sodium nitrite.
