Only the limited studies have been done on the effects of vibration exposure on reproductive indices, however vibration exposure has been indicated as being a hazardous agents with the potential of being able to directly affect the reproductive system. Considering the importance of infertility, the present study was conducted with the aim of investigating semen quality among taxi drivers in Tehran and determine the effect of exposure to WBV on sperm parameters. The study population consisted of 70 taxi drivers and 70 office employee who attended infertility clinics for diagnostic purposes in the past year. The participants had to meet the entry criteria of the study while also being willing to recruit. Data was collected in the form of demographic questionnaires and general health questionnaires as well as sperm analysis conducted in an infertility clinic according to standard laboratory guidelines. The 8-hour time-weighted average (TWA) exposure to of WBV in automobile was measured as per ISO 2631-1. The TWA exposure to WBV among the taxi drivers and office employees were 0.697\u2009\u00b1\u20090.13\u2009m\/s<jats:sup>2<\/jats:sup> and 0.068\u2009\u00b1\u20090.09\u2009m\/s<jats:sup>2<\/jats:sup> respectively (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.05). A statistically significant difference in total sperm count, progressive motility, non-progressive motility and total motility was observed between the taxi drivers and the office employees (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.05). According to the univariate analysis of variance, exposure to WBV had negative effect on sperm concentration, progressive motility and normal morphology (<jats:italic>P<\/jats:italic>\u2009&gt;\u20090.05); moreover exposure to WBV resulted in the larger effect size (B) on sperm parameters than the demographic variables (<jats:italic>P<\/jats:italic>\u2009&gt;\u20090.05). Being taxi drivers increase the chance of the decreased semen quality (<jats:italic>P<\/jats:italic>\u2009&gt;\u20090.05). It is difficult to draw definitive conclusions regarding the effects of WBV while intervening factors exist, such as psychological stressors, quality of sleep, background issues as well as environmental factors such as chemical pollutants (heavy metals) or ergonomic factors (body posture and working while sitting down).<\/jats:p>","DOI":"10.1186\/s12995-022-00357-z","type":"journal-article","created":{"date-parts":[[2022,8,3]],"date-time":"2022-08-03T07:04:02Z","timestamp":1659510242000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Assessment of semen quality of taxi drivers exposed to whole body vibration"],"prefix":"10.1186","volume":"17","author":[{"given":"Sirvan","family":"Zarei","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6607-6396","authenticated-orcid":false,"given":"Somayeh Farhang","family":"Dehghan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammad Hossein","family":"Vaziri","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammad Ali Sadighi","family":"Gilani","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Soheila Khodakarim","family":"Ardakani","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2022,8,3]]},"reference":[{"key":"357_CR1","doi-asserted-by":"publisher","unstructured":"Burgel BJ, Gillen M, White MC.
