Introduction: 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).

Conclusion: 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.

The worldwide spread of COVID-19 as an emerging, rapidly evolving situation, and the dramatic need of urgent medicine or vaccine, has rapidly brought new hypotheses for pathophysiology and potential medicinal agents to the fore. It is crucial that the research community provide a way to publish this research in a timely manner.


To contribute to this important public health discussion, the Electronic Physician Journal is excited to announce a fast-track procedure to help researchers publish their articles on COVID-19 related subjects that fall under the broad definition of public health, internal medicine, and pharmacology. We are especially welcome to all hypotheses about the pathological basis of the COVID-19 infection and the possible characteristics of potential medicine and vaccine. Submit your manuscript here
