While reactive oxygen species (ROS) are implicated in many important roles, from spermatogenesis to fertilization, epigenetic mechanisms which are transmissible to offspring have also recently been described. The present review is focused on the dual aspects of ROS, which are regulated by a delicate equilibrium with antioxidants due to the special frailty of spermatozoa, in continuum from physiological condition to OS. When the ROS production is excessive, OS ensues and is amplified by a chain of events leading to damage of lipids, proteins and DNA, ultimately causing infertility and\/or precocious pregnancy termination. After a description of positive ROS actions and of vulnerability of spermatozoa due to specific maturative and structural characteristics, we linger on the total antioxidant capacity (TAC) of seminal plasma, which is a measure of non-enzymatic non-proteic antioxidants, due to its importance as a biomarker of the redox status of semen; the therapeutic implications of these mechanism play a key role in the personalized approach to male infertility.<\/jats:p>","DOI":"10.3390\/ijms24054994","type":"journal-article","created":{"date-parts":[[2023,3,6]],"date-time":"2023-03-06T03:49:08Z","timestamp":1678074548000},"page":"4994","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["The Dual Role of Oxidants in Male (In)fertility: Every ROSe Has a Thorn"],"prefix":"10.3390","volume":"24","author":[{"given":"Antonio","family":"Mancini","sequence":"first","affiliation":[{"name":"Dipartimento di Medicina e Chirurgia Traslazionale, Universit\u00e0 Cattolica del Sacro Cuore, 00168 Rome, Italy"},{"name":"Fondazione Policlinico Universitario Agostino Gemelli IRCCS, 00168 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alessandro","family":"Oliva","sequence":"additional","affiliation":[{"name":"Dipartimento di Medicina e Chirurgia Traslazionale, Universit\u00e0 Cattolica del Sacro Cuore, 00168 Rome, Italy"},{"name":"Fondazione Policlinico Universitario Agostino Gemelli IRCCS, 00168 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Edoardo","family":"Vergani","sequence":"additional","affiliation":[{"name":"Dipartimento di Medicina e Chirurgia Traslazionale, Universit\u00e0 Cattolica del Sacro Cuore, 00168 Rome, Italy"},{"name":"Fondazione Policlinico Universitario Agostino Gemelli IRCCS, 00168 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roberto","family":"Festa","sequence":"additional","affiliation":[{"name":"Dipartimento di Medicina e Chirurgia Traslazionale, Universit\u00e0 Cattolica del Sacro Cuore, 00168 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2005-3746","authenticated-orcid":false,"given":"Andrea","family":"Silvestrini","sequence":"additional","affiliation":[{"name":"Fondazione Policlinico Universitario Agostino Gemelli IRCCS, 00168 Rome, Italy"},{"name":"Dipartimento di Scienze Biotecnologiche di Base, Cliniche Intensivologiche e Perioperatorie, Universit\u00e0 Cattolica del Sacro Cuore, 00168 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,3,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"183","DOI":"10.1095\/biolreprod41.1.183","article-title":"Generation of reactive oxygen species, lipid peroxidation and human sperm function","volume":"40","author":"Aitken","year":"1989","journal-title":"Biol.
