This study uncovers the persistence of 22 viruses in human semen, emphasizing the need for updated public health strategies and insights into fertility impacts.
By Vijay Kumar MalesuReviewed by Lily Ramsey, LLMDec 16 2024 A comprehensive review uncovers the persistence of 22 viruses in human semen post-infection, highlighting implications for disease transmission, fertility, and future research priorities.
Due to immune privilege, the male reproductive tract can serve as a viral reservoir, facilitating extended viral shedding despite systemic clearance. Searches were conducted across five databases- Public/Publisher MEDLINE , Excerpta Medica Database , Web of Science, Scopus, and the Program for Monitoring Emerging Diseases - covering disciplines relevant to the research questions.
The review employed a two-stage search strategy: stage one identified viruses detected in semen post-acute infection, while stage two explored evidence of sexual transmission. Titles, abstracts, and full texts were screened systematically using Rayyan software, with conflicts resolved by consensus. Deduplication and reference screening ensured comprehensive inclusion.
In stage 2, an additional 5,481 studies were identified, with 325 retained for full-text review. Through reference screening of review articles, 61 more articles were included. Ultimately, 373 studies met the eligibility criteria and were included in the analysis. For instance, in studies with systematic testing of participants, detection rates varied widely: 5-73% for Ebola virus disease, 33-100% for Zika virus, and 0-16% for coronavirus disease 2019 .
