A comprehensive search of the MEDLINE-PubMed database was conducted from inception to 28 April 2023, and a total of 67 eligible articles were selected. Data on 451 genes were extracted and analysed using a custom scoring system, revealing a strong association between altered seminal parameters and the expression of nine mRNA: <em>AKAP4, DDX4, PGK2, PIWIL1, PRM1, PRM2, TNP1, TNP2</em> and <em>PLCZ1</em>.
