A progressive sperm quality decline, and a decline in male fertility, have been reported in recent decades. Several studies have reported a strict relationship between obesity and male reproductive dysfunction. Among the many mechanisms by which obesity impairs male gonadal function, sirtuins (SIRTs) have an emerging role. SIRTs are highly conserved nicotinamide adenine dinucleotide (NAD+)-dependent deacetylases that play a role in gene regulation, metabolism, aging, and cancer. SIRTs regulate the energy balance, the lipid balance, glucose metabolism, and adipogenesis, but current evidence also indicates a role for SIRTs in male reproduction. However, the majority of the studies have been conducted in animal models and very few have been conducted with humans. This review shows that SIRTs play an important role among the molecular mechanisms by which obesity interferes with male fertility. This highlights the need to deepen this relationship. It will be of particular interest to evaluate whether synthetic and\/or natural compounds capable of modifying the activity of SIRTs may also be useful for the treatment of obesity and its effects on gonadal function. Although few studies have explored the role of SIRT activators in obesity-induced male infertility, some molecules, such as resveratrol, appear to be effective in modulating SIRT activity, as well as counteracting the negative effects of obesity on male fertility. The search for strategies to improve male reproductive function in overweight\/obese patients is a challenge and understanding the role of SIRTs and their activators may open new interesting scenarios in the coming years.<\/jats:p>","DOI":"10.3390\/ijms23020973","type":"journal-article","created":{"date-parts":[[2022,1,16]],"date-time":"2022-01-16T20:44:00Z","timestamp":1642365840000},"page":"973","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["Obesity and Male Reproduction: Do Sirtuins Play a Role?"],"prefix":"10.3390","volume":"23","author":[{"given":"Federica","family":"Barbagallo","sequence":"first","affiliation":[{"name":"Department of Clinical and Experimental Medicine, University of Catania, 95123 Catania, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7113-2372","authenticated-orcid":false,"given":"Sandro","family":"La Vignera","sequence":"additional","affiliation":[{"name":"Department of Clinical and Experimental Medicine, University of Catania, 95123 Catania, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4599-8487","authenticated-orcid":false,"given":"Rossella","family":"Cannarella","sequence":"additional","affiliation":[{"name":"Department of Clinical and Experimental Medicine, University of Catania, 95123 Catania, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2341-0996","authenticated-orcid":false,"given":"Laura M.","family":"Mongio\u00ec","sequence":"additional","affiliation":[{"name":"Department of Clinical and Experimental Medicine, University of Catania, 95123 Catania, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vincenzo","family":"Garofalo","sequence":"additional","affiliation":[{"name":"Department of Clinical and Experimental Medicine, University of Catania, 95123 Catania, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Claudia","family":"Leanza","sequence":"additional","affiliation":[{"name":"Department of Clinical and Experimental Medicine, University of Catania, 95123 Catania, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marta","family":"Marino","sequence":"additional","affiliation":[{"name":"Department of Clinical and Experimental Medicine, University of Catania, 95123 Catania, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6950-335X","authenticated-orcid":false,"given":"Aldo E.","family":"Calogero","sequence":"additional","affiliation":[{"name":"Department of Clinical and Experimental Medicine, University of Catania, 95123 Catania, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5217-9343","authenticated-orcid":false,"given":"Rosita A.","family":"Condorelli","sequence":"additional","affiliation":[{"name":"Department of Clinical and Experimental Medicine, University of Catania, 95123 Catania, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,1,16]]},"reference":[{"key":"ref_1","unstructured":"World Health Organization (2021, November 30).
