This condition is considered to be of high importance in the contemporary world. Objectives: To systematically review the literature on the impact of oral zinc supplementation on male infertility and to assess whether its intake exerts a therapeutic effect, based on the evaluation of seminal parameters, according to manuals published by the WHO. Methodology: A systematic review was carried out by means of a search, in the English and Portuguese languages, for original articles in the Pubmed, Science Direct, Lilacs and Scielo scientific databases. Results: The intervention groups ranged from 18 to 77 individuals and the control groups ranged from 8 to 113 individuals. Regarding age, the average age of the participants in the studies was 31 years. The daily dose of zinc administered in the trials varied from 66mg to 500mg and its use time ranged from three to six months. In the end, 87.5% of the studies showed positive results on the sperm parameters evaluated after the intervention. Conclusion: The results were mainly attributed to the protective effect that the trace element provided, reducing the lipid peroxidation index of plasma membranes and improving DNA integrity, thus increasing the fertilization capacity. </p>}, number={1}, journal={Ïã¸ÛÁùºÏ²Ê¿ª½±½á¹û}, author={Jean F. de Lima and Natália V.
