Seminal plasma (SP) is the biological fluid derived from the male accessory sex gland which carries spermatozoa passing throughout the male and female reproductive tract during ejaculation. It contains a complicated set of heterogeneous molecular structures, including proteins, cell-free nucleic acid (DNA, microRNA and LncRNA), and small-molecule metabolites as well as inorganic chemicals (ions). For a long time, the substantial significance of seminal plasma factors\u2019 functions has been underestimated, which is restricted to spermatozoa transport and protection. Notably, significant advancements have been made in dissecting seminal plasma components, revealing new insights into multiple aspects of sperm function, as well as fertilization and pregnancy outcomes in recent years. In this review, we summarize the state-of-art discoveries regarding SP compositions and their implications in male fertility, particularly describing the novel understanding of seminal plasma components and related modifications using \u201comics\u201d approaches and mainly focusing on proteome and RNA-seq data in the latest decade. Meanwhile, we highlighted the proposed mechanism of the regulation of SP molecules on immunomodulation in the female reproductive tract. Moreover, we also discussed the proteins investigated as non-invasive diagnosis biomarkers for male infertility in the clinic.<\/jats:p>","DOI":"10.3390\/ijms21228499","type":"journal-article","created":{"date-parts":[[2020,11,12]],"date-time":"2020-11-12T10:00:32Z","timestamp":1605175232000},"page":"8499","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":49,"title":["The Vehicle Determines the Destination: The Significance of Seminal Plasma Factors for Male Fertility"],"prefix":"10.3390","volume":"21","author":[{"given":"Fengli","family":"Wang","sequence":"first","affiliation":[{"name":"Institute Reproductive Health, Tongji Medical College, Huazhong University of Science and Technology, Wuhan 430030, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weina","family":"Yang","sequence":"additional","affiliation":[{"name":"Institute Reproductive Health, Tongji Medical College, Huazhong University of Science and Technology, Wuhan 430030, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sijin","family":"Ouyang","sequence":"additional","affiliation":[{"name":"Institute Reproductive Health, Tongji Medical College, Huazhong University of Science and Technology, Wuhan 430030, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuiqiao","family":"Yuan","sequence":"additional","affiliation":[{"name":"Institute Reproductive Health, Tongji Medical College, Huazhong University of Science and Technology, Wuhan 430030, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,11,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"575","DOI":"10.1093\/humupd\/dmr015","article-title":"Defining infertility\u2014A systematic review of prevalence studies","volume":"17","author":"Gurunath","year":"2011","journal-title":"Hum.
