This study aimed to evaluate the role of seminal isoprostane levels and sperm characteristics in the reproductive outcome and embryo quality of 49 infertile couples. Semen analysis was performed following WHO guidelines. Sperm chromatin maturity was detected using an aniline blue (AB) assay, and DNA integrity was assessed using the acridine orange (AO) test. Seminal F2-IsoP levels were quantified by gas chromatography\/negative ion chemical ionization tandem mass spectrometry (GC\/NICI\u2013MS\/MS) analysis. Correlations among variables and their impact on in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) outcome were investigated. F2-IsoP levels are positively correlated with double-stranded DNA sperm (p &lt; 0.001) and negatively correlated with mature sperm chromatin (p &lt; 0.001). Patients with positive outcomes had an increased percentage of sperm with double-stranded DNA, as did patients producing high-quality embryo, who showed higher F2-IsoP levels compared to those detected in the low-quality embryo group. An intriguing relationship between a mild increase in F2-IsoP levels, DNA integrity, and embryo quality seems to indicate that the non-enzymatic oxidation of arachidonic acid can be also a marker of metabolic activity in human semen.<\/jats:p>","DOI":"10.3390\/life11070675","type":"journal-article","created":{"date-parts":[[2021,7,12]],"date-time":"2021-07-12T00:23:36Z","timestamp":1626049416000},"page":"675","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Do Seminal Isoprostanes Have a Role in Assisted Reproduction Outcome?"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1587-0159","authenticated-orcid":false,"given":"Giulia","family":"Collodel","sequence":"first","affiliation":[{"name":"Department of Molecular and Developmental Medicine, University of Siena, 53100 Siena, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1571-9056","authenticated-orcid":false,"given":"Daria","family":"Noto","sequence":"additional","affiliation":[{"name":"Department of Molecular and Developmental Medicine, University of Siena, 53100 Siena, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0006-9414","authenticated-orcid":false,"given":"Cinzia","family":"Signorini","sequence":"additional","affiliation":[{"name":"Department of Molecular and Developmental Medicine, University of Siena, 53100 Siena, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laura","family":"Gambera","sequence":"additional","affiliation":[{"name":"Fertility Center, AGI Medica, 53100 Siena, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anita","family":"Stendardi","sequence":"additional","affiliation":[{"name":"Fertility Center, AGI Medica, 53100 Siena, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amra","family":"Mahmutbegovic","sequence":"additional","affiliation":[{"name":"Department of Molecular and Developmental Medicine, University of Siena, 53100 Siena, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0306-9308","authenticated-orcid":false,"given":"Lucia","family":"Micheli","sequence":"additional","affiliation":[{"name":"Department of Medicine, Surgery and Neurosciences, University of Siena, 53100 Siena, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8194-0613","authenticated-orcid":false,"given":"Andrea","family":"Menchiari","sequence":"additional","affiliation":[{"name":"Department of Business and Law, University of Siena, 53100 Siena, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9467-0501","authenticated-orcid":false,"given":"Elena","family":"Moretti","sequence":"additional","affiliation":[{"name":"Department of Molecular and Developmental Medicine, University of Siena, 53100 Siena, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,7,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1039","DOI":"10.1002\/mrd.22871","article-title":"Reactive oxygen species as mediators of sperm capacitation and pathological damage","volume":"84","author":"Aitken","year":"2017","journal-title":"Mol.
