We evaluated the links between leptin and visfatin levels and fertilization rates in nonoverweight (NOW) women with PCOS (NOW-PCOS) from Apulia undergoing in vitro fertilization\/embryo transfer (IVF).<jats:italic>Materials and Methodology<\/jats:italic>. We recruited 16 NOW women with PCOS (NOW-PCOS) and 10 normally ovulating NOW women (control-NOW). All women underwent IVF. Androgens, 17-<jats:italic>\u03b2<\/jats:italic>-estradiol (17<jats:italic>\u03b2<\/jats:italic>-E<jats:sub>2<\/jats:sub>), and insulin levels were measured in plasma and\/or serum and leptin and visfatin levels were assayed in both serum and follicular fluid (FF-leptin, FF-visfatin).<jats:italic>Results<\/jats:italic>. In NOW-PCOS, both serum and FF-leptin were significantly lower than in control-NOW. In NOW-PCOS, significant correlations were found between BMI and serum leptin and insulinemia and FF-leptin. By contrast, in control-NOW, FF-leptin levels were not correlated with insulinemia. Serum visfatin levels were not significantly different in NOW-PCOS and control-NOW, but FF-visfatin levels were 1.6-fold higher, although not significantly, in NOW-PCOS than in control-NOW.<jats:italic>Conclusions<\/jats:italic>. Both serum leptin levels and FF-leptin are BMI- and insulin-related in Southern Italian NOW-PCOS from Apulia. In line with other reports showing that FF-leptin levels are predictive of fertilization rates, lower than normal FF-leptin levels in NOW-PCOS may explain their lower fertilization rate and this may be related to the level of insulin and\/or insulin resistance.<\/jats:p>","DOI":"10.1155\/2014\/980429","type":"journal-article","created":{"date-parts":[[2014,5,4]],"date-time":"2014-05-04T21:10:04Z","timestamp":1399237804000},"page":"1-7","source":"Crossref","is-referenced-by-count":13,"title":["Association between Follicular Fluid Leptin and Serum Insulin Levels in Nonoverweight Women with Polycystic Ovary Syndrome"],"prefix":"10.1155","volume":"2014","author":[{"given":"G.","family":"Garruti","sequence":"first","affiliation":[{"name":"Section of Internal Medicine, Endocrinology, Andrology and Metabolic Diseases, Department of Emergency and Organ Transplantation, University of Bari Aldo Moro, Piazza G.
