The mean \u0392-carotene levels in follicular fluid [0.182 \u00b1 (SEM) 0.04 nmol\/ml] and plasma (0.37 \u00b1 0.34 mmol\/ml) of smokers (n = 5) were significantly (p &lt; 0.025 and p &lt; 0.001, respectively) lower compared with the mean levels in follicular fluid (0.58 \u00b1 0.10 nmol\/ml) and plasma (1.11 \u00b1 0.09 mmol\/ml) in nonsmokers (n = 11). The follicular fluid and plasma retinol and \u0391-tocopherol levels were comparable among the non-smokers and smokers. These findings direct attention to a possible role of the antioxidant \u0392-carotene, per se, as a biological marker in ovarian oocyte follicular maturation and function.<\/jats:p>","DOI":"10.1159\/000292374","type":"journal-article","created":{"date-parts":[[2010,3,2]],"date-time":"2010-03-02T02:53:55Z","timestamp":1267498435000},"page":"43-46","source":"Crossref","is-referenced-by-count":13,"title":["Effects of Smoking on the Levels of Antioxidant Beta Carotene, Alpha Tocopherol and Retinol in Human Ovarian Follicular Fluid"],"prefix":"10.1159","author":[{"given":"Prabhudas R.","family":"Palan","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brian L.","family":"Cohen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David H.","family":"Barad","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seymour L.","family":"Romney","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2010,3,1]]},"container-title":["Gynecologic and Obstetric Investigation"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000292374","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T06:09:54Z","timestamp":1777615794000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000292374"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010,3,1]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000292374","archive":["Portico"],"relation":{},"ISSN":["0378-7346","1423-002X"],"issn-type":[{"value":"0378-7346","type":"print"},{"value":"1423-002X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2010,3,1]]}}}
