Although the male contribution to human fertilization has traditionally been restricted to sperm DNA, current evidence suggest that a relevant number of sperm transcripts and proteins are involved in acrosome reactions, sperm\u2012oocyte fusion and, once released into the oocyte, embryo growth and development. The aim of this review is to provide updated and comprehensive insight into the molecular biology of spermatogenesis, including evidence on spermatogenetic failure and underlining the role of the sperm-carried molecular factors involved in oocyte fertilization and embryo growth. This represents the first step in the identification of new possible diagnostic and, possibly, therapeutic markers in the field of apparently idiopathic male infertility.<\/jats:p>","DOI":"10.3390\/ijms21051728","type":"journal-article","created":{"date-parts":[[2020,3,3]],"date-time":"2020-03-03T13:06:23Z","timestamp":1583240783000},"page":"1728","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":114,"title":["Molecular Biology of Spermatogenesis: Novel Targets of Apparently Idiopathic Male Infertility"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4599-8487","authenticated-orcid":false,"given":"Rossella","family":"Cannarella","sequence":"first","affiliation":[{"name":"Department of Clinical and Experimental Medicine, University of Catania, 95123 Catania, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"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":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laura M.","family":"Mongio\u00ec","sequence":"additional","affiliation":[{"name":"Department of Clinical and Experimental Medicine, University of Catania, 95123 Catania, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"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":[{"vocabulary":"crossref","role":"author"}]},{"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":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,3,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"37","DOI":"10.1186\/s12958-015-0032-1","article-title":"A unique view on male infertility around the globe","volume":"13","author":"Agarwal","year":"2015","journal-title":"Reprod.
