This study found that approximately 75% of women with PCOS exhibited hyperandrogenemia, with free testosterone being the most frequently elevated marker.

In this study, PCOS was the most common cause of hirsutism among Turkish women, but about 17% had idiopathic hyperandrogenemia with no clear cause identified.

This review summarizes the influence of gene polymorphisms on genetic predisposition to polycystic ovary syndrome, but reports no new experimental or clinical results.

This study found that calculated parameters like free testosterone and bioavailable testosterone were higher in women with hirsutism and PCOS compared to controls, suggesting these might better assess hyperandrogenemia than measured hormone values.

This study found a high prevalence of hyperandrogenemia in women with PCOS, with distinct biochemical differences according to BMI and presence of hyperandrogenemia.

This study established a normative free androgen index range of 0.7-6.4 and identified a cut-off value of 6.1 for reproductive-age women in southern China, highlighting hyperandrogenic women's increased metabolic disorder risks.

This study determined that the upper normal cut-off levels for free testosterone, dehydroepiandrosterone sulfate, and total testosterone among reproductive-age women in China are 26 pmol/L, 4.92 μmol/L, and 2.39 nmol/L, respectively.

This study found that obesity in PCOS women with biochemical hyperandrogenemia lowers androstenedione levels and increases the testosterone to androstenedione ratio, but this was not observed in women with clinical hyperandrogenemia or in controls.

This review discusses the evaluation of hyperandrogenemia in women and hypogonadism in men across different life stages and presents biomarkers used for diagnosing male hypogonadism, reporting no new clinical results.

This study suggests that androstendione and DHEA are useful indicators for diagnosing hyperandrogenemia in hirsute women, while DHEAS was not found to be helpful.

Blood AMH levels are higher in women with PCOS than in those with other similar conditions.

This review describes two cases of young women with primary amenorrhea and hyperandrogenemia, suggesting that adrenal tumors should be considered in patients with significantly elevated circulating testosterone levels.

This study suggests a relationship between insulin resistance and androgenetic alopecia in women, independent of hyperandrogenemia.

This study found that in PCOS women, polycystic ovarian morphology is linked to more severe hormonal imbalances and insulin resistance, especially in those who are overweight or obese.

This case report details a postmenopausal woman with increased libido, hirsutism, and spontaneous orgasms, noting elevated testosterone levels and enlarged ovaries.

This case report describes an obese young adolescent girl with PCOS who presented with high testosterone levels and severe hyperinsulinemia, successfully treated with continuous combined oral contraceptives.

In this study, researchers found that a specific genetic variant in the INSR gene is linked to severe insulin resistance and hyperandrogenemia in type A insulin resistance syndrome, suggesting the benefit of exon sequencing for accurate diagnosis and treatment.

In this study, among women with polycystic ovary syndrome, free testosterone was most frequently elevated, highlighting its importance in biochemical assessment and suggesting the need for age-related interpretation of DHEAS levels.

In this case study, authors reported that a 43-year-old female patient initially showed persistently high testosterone levels due to immunoassay interference, later verified as normal using liquid chromatography-tandem mass spectrometry (LC-MS/MS), highlighting the need to consider assay artifacts in diagnosing hyperandrogenism without clinical signs.

This study found that total testosterone, DHEA-S, and free androgen index may help distinguish menstrual irregularities from increased risk of polycystic ovary syndrome in adolescents.

This study explored the clinical and biochemical hyperandrogenic status in adolescents with irregular menses to identify significant indicators of potential metabolic problems linked to PCOS.

This case series detailed three postmenopausal women with ovarian steroid cell tumors, highlighting that such tumors may present asymptomatically or with virilization, and found surgery effectively normalized androgen levels, with distinctive imaging features aiding diagnosis.

This study found that CYP21A2 gene mutations are the most common cause of non-classic congenital adrenal hyperplasia, while CYP11B1 mutations are rare and may partially impair enzyme activity.

This study found that pregnancies with gestational diabetes in a Midwestern U.S. cohort demonstrated elevated androgen levels compared to healthy controls, suggesting a common relationship between impaired glucose tolerance and hyperandrogenemia across diverse ethnic backgrounds.

This review discusses the relationship between hyperandrogenism and insulin resistance in PCOS, focusing on insulin dynamics, molecular mechanisms, genetic studies, and potential long-term treatments, but presents no new clinical results.

This study found that women with idiopathic hyperandrogenemia had higher urinary Bisphenol A levels compared to healthy controls, suggesting a potential role of this chemical in the condition.

In this case study, laparoscopic bilateral salpingo-oophorectomy was associated with reduced androgen levels and partial reversal of male-pattern hair loss in a postmenopausal woman with ovarian hyperandrogenism.

In this study, treating prolactinoma with cabergoline normalized prolactin levels and affected some androgen-related parameters, but did not significantly improve hirsutism in affected women.
