Calorie restriction (CR) diets and glucagon-Like Peptide-1 (GLP-1) analogs are known to alter energy homeostasis with the potential to affect the expression of obesity-related genes (ORGs). We hypothesized that CR and GLP-1 administration can alter ORGs expression in spermatozoa and testes, as well as the sperm parameters implicated in male fertility. Materials and Methods: Six-week-old adult male Wistar rats (n = 16) were divided into three groups, submitted either to CR (n = 6, fed with 30% less chow diet than the control rats), GLP-1 administration (n = 5, 3.5 pmol\/min\/kg intraperitoneal) for 28 days, or used as controls (n = 5, fed ad libitum). Selected ORGs expression, namely the fat mass and obesity-associated (FTO), melanocortin-4 receptor (MC4R), glucosamine-6-phosphate deaminase 2 (GNPDA2), and transmembrane protein 18 (TMEM18) were evaluated in testes and spermatozoa by a quantitative polymerase chain reaction (qPCR). Results: CR resulted in lower body weight gain and insulin resistance, but a higher percentage of sperm head defects. GLP-1 administration, despite showing no influence on body weight or glucose homeostasis, resulted in a lower percentage of sperm head defects. CR and GLP-1 administration were associated with a higher expression of all ORGs in the testes. Under CR conditions, the genes FTO and TMEM18 expression in the testes and the MC4R and TMEM18 transcripts abundance in sperm were positively correlated with the spermatozoa oxidative status. The abundance of FTO and TMEM18 in the spermatozoa of rats under CR were positively correlated with sperm concentration, while the testes\u2019 TMEM18 expression was also positively correlated with sperm vitality and negatively correlated with insulin resistance. Testes GNPDA2 expression was negatively correlated with sperm head defects. Conclusions: CR and GLP-1 administration results in higher ORGs expression in testes, and these were correlated with several alterations in sperm fertility parameters.<\/jats:p>","DOI":"10.3390\/biomedicines10102609","type":"journal-article","created":{"date-parts":[[2022,10,17]],"date-time":"2022-10-17T21:11:51Z","timestamp":1666041111000},"page":"2609","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Obesity-Related Genes Expression in Testes and Sperm Parameters Respond to GLP-1 and Caloric Restriction"],"prefix":"10.3390","volume":"10","author":[{"given":"Ana S.","family":"Correia","sequence":"first","affiliation":[{"name":"LAQV-REQUIMTE and Department of Chemistry, Campus Universitario de Santiago, University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2363-5431","authenticated-orcid":false,"given":"Sara C.","family":"Pereira","sequence":"additional","affiliation":[{"name":"LAQV-REQUIMTE and Department of Chemistry, Campus Universitario de Santiago, University of Aveiro, 3810-193 Aveiro, Portugal"},{"name":"Endocrine and Metabolic Research, Unit for Multidisciplinary Research in Biomedicine, Department of Anatomy, School of Medicine and Biomedical Sciences (ICBAS), University of Porto, 4050-313 Porto, Portugal"},{"name":"Laboratory for Integrative and Translational Research in Population Health (ITR), University of Porto, 4099-002 Porto, Portugal"},{"name":"Department of Pathology, Faculty of Medicine, University of Porto, 4200-319 Porto, Portugal"}]},{"given":"Tiago","family":"Morais","sequence":"additional","affiliation":[{"name":"Endocrine and Metabolic Research, Unit for Multidisciplinary Research in Biomedicine, Department of Anatomy, School of Medicine and Biomedical Sciences (ICBAS), University of Porto, 4050-313 Porto, Portugal"}]},{"given":"Ana D.","family":"Martins","sequence":"additional","affiliation":[{"name":"LAQV-REQUIMTE and Department of Chemistry, Campus Universitario de Santiago, University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0662-1831","authenticated-orcid":false,"given":"Mariana P.","family":"Monteiro","sequence":"additional","affiliation":[{"name":"Endocrine and Metabolic Research, Unit for Multidisciplinary Research in Biomedicine, Department of Anatomy, School of Medicine and Biomedical Sciences (ICBAS), University of Porto, 4050-313 Porto, Portugal"},{"name":"Laboratory for Integrative and Translational Research in Population Health (ITR), University of Porto, 4099-002 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7635-783X","authenticated-orcid":false,"given":"Marco G.","family":"Alves","sequence":"additional","affiliation":[{"name":"Endocrine and Metabolic Research, Unit for Multidisciplinary Research in Biomedicine, Department of Anatomy, School of Medicine and Biomedical Sciences (ICBAS), University of Porto, 4050-313 Porto, Portugal"},{"name":"Laboratory for Integrative and Translational Research in Population Health (ITR), University of Porto, 4099-002 Porto, Portugal"},{"name":"Biotechnology of Animal and Human Reproduction (TechnoSperm), Institute of Food and Agricultural Technology, University of Girona, ES-17003 Girona, Spain"},{"name":"Unit of Cell Biology, Department of Biology, Faculty of Sciences, University of Girona, ES-17003 Girona, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4989-5699","authenticated-orcid":false,"given":"Pedro F.","family":"Oliveira","sequence":"additional","affiliation":[{"name":"LAQV-REQUIMTE and Department of Chemistry, Campus Universitario de Santiago, University of Aveiro, 3810-193 Aveiro, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"963","DOI":"10.1177\/153537020122601102","article-title":"Peripheral Signals Conveying Metabolic Information to the Brain: Short-Term and Long-Term Regulation of Food Intake and Energy Homeostasis","volume":"226","author":"Havel","year":"2001","journal-title":"Exp.
