title: Would Phoenix Dactyflera Pollen (palm seed) be considered as a treatment agent against Males' infertility? A systematic review.
abstract: BACKGROUND
  Oxidative stress is a key factor involved in male infertility, which is due to an unnatural increase in environmental free radicals. In the majority of cases, this has a negative effect on a male's ability to impregnate a female. Currently, it is believed that spermatozoa can be protected against the damages induced by oxidative stress by saturating sperm with antioxidants. The antioxidant role of phoenix dactylifera pollen is capable of collecting the reactive oxygen and neutralizing it in and out of body cells. The present research provides a review of the antioxidant roles of phoenix dactylifera pollen on male infertility.
  
  
  METHODS
  This research is based on English-Language studies and articles found by comprehensively reviewing electronic databases, websites, books, and academic articles over the last 10 years.
  
  
  RESULTS
  The phenolic compounds of phoenix dactylifera pollen, due to the existing polyphenols, are strong chelators of heavy metals. Therefore, they are effective in eliminating environmental hydroxyl radicals. Moreover, these plants have high capacities of eliminating hydroxyl free radicals, picrylhydrazyl, diphenyl and phoenix dactylifera pollen and also inhibiting glutathione-S-transferase (GST).
  
  
  CONCLUSIONS
  Currently, the use of herbal antioxidants to neutralize reactive oxygen species (ROS) and reduce the negative effects of oxidative stress on body cells and tissues has attracted researchers' attention. Various substances, such as flavonoids and catechins, perform their antioxidant role by increasing the concentration of glutathione peroxidase. The final product of this process is an increase in the number of motile sperm, which can have significant effects on fertility.
