Regarding the human population exposed to uranium, it is necessary to explore these effects on male reproduction in multigenerational studies. The sensitivity of mass spectrometry (MS)-based methods has already proved to be extremely useful in metabolite identification in rats exposed to low doses of uranium, but also in human sperm. We applied this method to rat sperm over three generations (F0, F1 and F2) with multigenerational uranium exposure. Our results show a significant content of uranium in generation F0, and a reduction in the pregnancy rate only in generation F1. Based on principal component analysis (PCA), we observed discriminant profiles between generations. The partial least squares discriminant analysis (PLS-DA) of the 48 annotated variables confirmed that parental exposure of generation F0 (during both the preconceptional and prenatal periods) can have metabolic effects on spermatozoa for the next two generations. Metabolomics applied to epididymal spermatozoa is a novel approach to detecting the multigenerational effects of uranium in an experimental model, but could be also recommended to identify potential biomarkers evaluating the impact of uranium on sperm in exposed infertile men.<\/jats:p>","DOI":"10.3390\/ijms23158349","type":"journal-article","created":{"date-parts":[[2022,7,28]],"date-time":"2022-07-28T20:49:28Z","timestamp":1659041368000},"page":"8349","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Multigenerational Exposure to Uranium Changes Sperm Metabolome in Rats"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1569-7547","authenticated-orcid":false,"given":"St\u00e9phane","family":"Grison","sequence":"first","affiliation":[{"name":"Institut de Radioprotection et de S\u00fbret\u00e9 Nucl\u00e9aire, PSE-SANTE, 92260 Fontenay-aux-Roses, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Audrey","family":"Legendre","sequence":"additional","affiliation":[{"name":"Institut de Radioprotection et de S\u00fbret\u00e9 Nucl\u00e9aire, PSE-SANTE, 92260 Fontenay-aux-Roses, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3219-0860","authenticated-orcid":false,"given":"Ljubica","family":"Svilar","sequence":"additional","affiliation":[{"name":"C2VN, CRIBIOM, Aix Marseille Universit\u00e9, 13007 Marseille, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christelle","family":"Elie","sequence":"additional","affiliation":[{"name":"Institut de Radioprotection et de S\u00fbret\u00e9 Nucl\u00e9aire, PSE-SANTE, 92260 Fontenay-aux-Roses, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dimitri","family":"Kereselidze","sequence":"additional","affiliation":[{"name":"Institut de Radioprotection et de S\u00fbret\u00e9 Nucl\u00e9aire, PSE-SANTE, 92260 Fontenay-aux-Roses, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C\u00e9line","family":"Gloaguen","sequence":"additional","affiliation":[{"name":"Institut de Radioprotection et de S\u00fbret\u00e9 Nucl\u00e9aire, PSE-SANTE, 92260 Fontenay-aux-Roses, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Philippe","family":"Lestaevel","sequence":"additional","affiliation":[{"name":"Institut de Radioprotection et de S\u00fbret\u00e9 Nucl\u00e9aire, PSE-SANTE, 92260 Fontenay-aux-Roses, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2870-0012","authenticated-orcid":false,"given":"Jean-Charles","family":"Martin","sequence":"additional","affiliation":[{"name":"C2VN, INRAE, INSERM, BIOMET, Aix Marseille Universit\u00e9, 13007 Marseille, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ma\u00e2mar","family":"Souidi","sequence":"additional","affiliation":[{"name":"Institut de Radioprotection et de S\u00fbret\u00e9 Nucl\u00e9aire, PSE-SANTE, 92260 Fontenay-aux-Roses, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,7,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"191","DOI":"10.4103\/0974-1208.170370","article-title":"Trends of male factor infertility, an important cause of infertility: A review of literature","volume":"8","author":"Kumar","year":"2015","journal-title":"J.
