It is unknown if occupational exposure to Vat textile dyes among premenopausal dyers altershormonal levels.\r\nObjectives: We aimed at determining the probable effects of occupational exposure to Vat dyes on reproductive hormones offemale textile dyers in the follicular and luteal phases while relating this to age categories and duration of exposure.\r\nMethods: Thirty-three premenopausal Vat textile dyers at \u201cItoku\u201d, Abeokuta, Nigeria, among a population of about 80 femaledyers were age and sex-matched with 55 non-exposed (control) female participants. Using semi-structured questionnaires, socio-demographic, occupational details and the LMP of participants were obtained. Serum samples were collected in follicularand luteal phases and assayed for female sex hormones using Enzyme Immunoassay. Mann-Whitney U and Z- statistic were usedfor comparison of the two groups. P-value &lt; 0.05 was considered to be significant.\r\nResults: In the follicular phase, the result showed a lower mean FSH ranking (in age category \u226420 years) and higher (p&lt;0.05)Estradiol ranking (in age category 31-40 years) in the exposed than the unexposed. Mean ranks of Progesterone and Estradiol inthe luteal phase (age category 31-40 years) were higher (p&lt;0.05) in the exposed, while Estradiol (age category \u226541years) rankedlower (p&lt;0.05). Prolactin demonstrated a significant inverse relationship with the duration of exposure.\r\nConclusion: Occupational exposure to Vat dye among female dyers in Abeokuta is associated with some sex hormone disruptionwhich appears to be age and duration of exposure-related.\r\nKeywords: Follicular phase; luteal phase; dye workers; sex hormone; premenopausal.<\/jats:p>","DOI":"10.4314\/ahs.v24i1.17","type":"journal-article","created":{"date-parts":[[2024,5,17]],"date-time":"2024-05-17T11:38:27Z","timestamp":1715945907000},"page":"135-144","source":"Crossref","is-referenced-by-count":4,"title":["Effect of occupational exposure to vat-textile dyes on follicular and luteal hormones in female dye workers in Abeokuta, Nigeria"],"prefix":"10.4314","volume":"24","author":[{"given":"Oluwatosin","family":"O Soyinka","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akinwunmi","family":"F Akinsanya","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Festus","family":"A Odeyemi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adebayo","family":"A Amballi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Oritogun","family":"K Sunday","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Omobola","family":"A Ogundahunsi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2895","published-online":{"date-parts":[[2024,4,1]]},"container-title":["African Health Sciences"],"original-title":[],"link":[{"URL":"https:\/\/www.ajol.info\/index.php\/ahs\/article\/download\/267844\/252751","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.ajol.info\/index.php\/ahs\/article\/download\/267844\/252751","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,5,17]],"date-time":"2024-05-17T11:38:56Z","timestamp":1715945936000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ajol.info\/index.php\/ahs\/article\/view\/267844"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,4,1]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2024,4,1]]}},"URL":"https:\/\/doi.org\/10.4314\/ahs.v24i1.17","relation":{},"ISSN":["1729-0503","1680-6905"],"issn-type":[{"value":"1729-0503","type":"electronic"},{"value":"1680-6905","type":"print"}],"subject":[],"published":{"date-parts":[[2024,4,1]]}}}
