Although manual testing using microscope examination and computer-assisted semen analysis are standard methods of measuring sperm count and motility, these methods are limited by being laboratory based. To investigate the usefulness of a novel semen analysis device using a smartphone camera. This prospective multicenter randomized parallel design trial enrolled 200 men aged \u226519 years of age between August and December 2018. Each subject was advised to use the Smart Sperm Test for OVIEW-M at home after 5 days of abstinence. The accuracy of the OVIEW-M test relative to the in-hospital test was determined. A questionnaire was administered to assess subject likelihood of using the OVIEW-M. Measurements using standard methods and the OVIEW-M showed similar sperm counts and similar motile sperm counts. Correlation analysis showed significant correlations between sperm count and sperm motility when measured by OVIEW-M tests (r = 0.893, p &lt; 0.01) and standard microscope examination (r = 0.883, p &lt; 0.01). Of the subjects who responded to questionnaires, 43% regarded the results of the OVIEW-M tests as reliable and 18% as unreliable. Semen analysis with the smartphone-based application and accessories yielded results not inferior to those of laboratory tests. Men who visit the hospital for evaluation of infertility can easily perform OVIEW-M semen tests at home.<\/jats:p>","DOI":"10.1371\/journal.pone.0269894","type":"journal-article","created":{"date-parts":[[2022,6,16]],"date-time":"2022-06-16T17:38:11Z","timestamp":1655401091000},"page":"e0269894","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":6,"title":["Ability and accuracy of the smartphone-based O`VIEW-M\u00ae sperm test: Useful tool in the era of Covid-19"],"prefix":"10.1371","volume":"17","author":[{"given":"Kyu Shik","family":"Kim","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ji Hoon","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ji Hyoung","family":"Roh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daegwan","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hyang Mi","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6080-7493","authenticated-orcid":true,"given":"Jung Ki","family":"Jo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2022,6,16]]},"reference":[{"key":"pone.0269894.ref001","doi-asserted-by":"crossref","first-page":"e1001356","DOI":"10.1371\/journal.pmed.1001356","article-title":"National, regional, and global trends in infertility prevalence since 1990: a systematic analysis of 277 health surveys","volume":"9","author":"MN Mascarenhas","year":"2012","journal-title":"PLoS Med"},{"key":"pone.0269894.ref002","doi-asserted-by":"crossref","first-page":"707","DOI":"10.1038\/nrurol.2017.175","article-title":"Microfluidics for sperm analysis and selection","volume":"14","author":"R.
