Methods: In the present retrospective study, women with PCOS having normal fasting insulin sensitivity (n = 88) were compared with women with PCOS showing impaired insulin sensitivity (n = 46) using the HPCOS (Hungarian Polycystic ovarian syndrome) database. Results: The impaired insulin sensitivity group has significantly higher body mass index (BMI) and HOMA index than the normal fasting insulin sensitivity group (BMI (kg\/m2): 22.0 vs. 28.1, p &lt; 0.0001, HOMA index: 0.96 vs. 2.38, p &lt; 0.0001). The sex hormone binding globulin (SHBG) level was significantly lower, and the free androgen index proved itself significantly higher in the impaired insulin sensitivity group (p &lt; 0.05). Linear regression analysis showed a negative association of BMI with SHBG levels in both groups, while BMI had a positive correlation with insulin concentrations in both groups. However, the SHBG levels were negatively associated with insulin concentrations in the impaired insulin sensitivity group, but this inverse association could not be observed in the normal fasting insulin sensitivity group. Conclusions: The inverse linear correlation of SHBG with HOMA index and serum insulin level is not evident in all PCO syndrome phenotypes, thus SHBG has limited applicability for characterizing carbohydrate metabolism and serum insulin sensitivity.<\/jats:p>","DOI":"10.3390\/jcm13030838","type":"journal-article","created":{"date-parts":[[2024,2,1]],"date-time":"2024-02-01T09:43:22Z","timestamp":1706780602000},"page":"838","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["SHBG Levels Do Not Correlate with Insulin Levels in PCOS with Appropriate Fasting Insulin Sensitivity"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-0560-9053","authenticated-orcid":false,"given":"L\u00e1szl\u00f3","family":"T\u0171\u0171","sequence":"first","affiliation":[{"name":"EndoCare Institute, Endocrinology Center, 1095 Budapest, Hungary"},{"name":"School of PhD Studies, Semmelweis University, 1085 Budapest, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Katalin","family":"Nas","sequence":"additional","affiliation":[{"name":"EndoCare Institute, Endocrinology Center, 1095 Budapest, Hungary"},{"name":"School of PhD Studies, Semmelweis University, 1085 Budapest, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2832-0626","authenticated-orcid":false,"given":"Marianna","family":"T\u00f6r\u00f6k","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Semmelweis University, 1082 Budapest, Hungary"},{"name":"Workgroup of Research Management, Doctoral School, Semmelweis University, 1085 Budapest, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Szabolcs","family":"V\u00e1rb\u00edr\u00f3","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Semmelweis University, 1082 Budapest, Hungary"},{"name":"Workgroup of Research Management, Doctoral School, Semmelweis University, 1085 Budapest, Hungary"},{"name":"Department of Obstetrics and Gynecology, University of Szeged, 6725 Szeged, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,2,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"261","DOI":"10.4103\/jhrs.JHRS_95_18","article-title":"The Prevalence of Polycystic Ovary Syndrome: A Brief Systematic Review","volume":"13","author":"Deswal","year":"2020","journal-title":"J.
