This study observed two distinct phenotypes among North Indian women with PCOS: obese hyperinsulinaemic dysglycemic women from Delhi and lean hyperandrogenic women from Srinagar, despite being in the same region.

In this study, researchers observed that hyperandrogenic PCOS patients exhibited distinct miRNA and TGFβ signaling gene expression patterns in granulosa cells, suggesting these factors may play a role in PCOS pathogenesis.

This study proposes reclassifying PCOS into two distinct phenotypes based on androgen levels and suggests androgen supplementation may overcome IVF resistance in one group with advancing age.

This consensus paper reviews current challenges and recommendations for diagnosing and treating polycystic ovary syndrome, highlighting the utility of the Rotterdam criteria for adults and different criteria for teenagers without requiring polycystic ovaries.

In this study, researchers identified a novel genetic variant in the NR3C1 gene in a mother and her son that predicts a truncated protein, leading to glucocorticoid resistance syndrome with mild hyperandrogenic features, although no clear genotype-phenotype correlation has been established.

This study found that in patients with nonclassical 21-hydroxylase deficiency, genotypes do not reliably predict the severity of hyperandrogenic symptoms, suggesting other genetic factors may influence the phenotype.

This study found that in a sample of female adolescents in Shiraz, the most common PCOS phenotype was hyperandrogenic with polycystic ovary syndrome, warranting further investigation due to associated risks.

This review discusses the challenges in measuring testosterone for assessing androgen excess in women and emphasizes the importance of quality control in laboratory methods, but it reports no new clinical results.

This study reports that NIH PCOS is linked to more severe metabolic issues, including higher obesity and insulin resistance, compared to non-NIH PCOS phenotypes.

This review discusses definitions of polycystic ovary syndrome and reports no new clinical results; the authors support using modified 1990 NIH criteria and acknowledge ongoing evolution as research advances.

This review discusses the complex correlation between cellular senescence and PCOS, emphasizing senescence markers, mechanisms, and potential anti-senescence therapies, but reports no new clinical results.

This study reports that women with polycystic ovary syndrome, especially those with a hyperandrogenic pattern, are at a higher risk for cardiovascular disease compared to other PCOS patients, likely due to related metabolic comorbidities.

This case report describes a 15-year-old girl with severe hyperandrogenaemia linked to both an ovarian androgen-secreting tumor and HAIR-AN syndrome, highlighting the complexity of diagnosing polycystic ovarian syndrome.

This study found that young indigenous South Asian women with polycystic ovary syndrome are more likely to be centrally obese and have metabolic syndrome, particularly with increasing age, higher BMI, and acanthosis nigricans.

This study found that late adolescent and young women with clinical hyperandrogenism, including PCOS, experienced higher psychological distress and impaired well-being compared to their healthy peers.

This study found that a basal 17-hydroxyprogesterone level is effective for screening nonclassic adrenal hyperplasia in women, with a 4 ng/mL cutoff providing high specificity and positive predictive value.

The study found that women with hyperandrogenic PCOS have higher levels of AKT1 and AKT2 proteins in their cells, which may lead to cell dysfunction.

This study concluded that neither basal nor ACTH-stimulated 17-OHP concentrations effectively indicate carrier status for 21-hydroxylase deficiency among Slovenian hyperandrogenic women, recommending molecular analysis of the CYP21 gene for reliable screening.

This study found that in women with PCOS, suppressive therapy using spironolactone plus oral contraceptives improved hirsutism more effectively than either treatment alone, with initial scores predicting success.

Finasteride helps induce ovulation in nonresponder PCOS women.

This review discusses the age-related diagnostic challenges and comorbidities of polycystic ovarian syndrome and provides no new clinical findings; the authors emphasize the role of obesity in insulin resistance among affected women.

This study found that women with polycystic ovary syndrome phenotypes A and B had the highest prevalence of metabolic syndrome, and that the visceral adiposity index may help predict metabolic risk.

This study found that Myoinositol and D-chiro inositol treatment improved fertility outcomes in women with PCOS, particularly in Phenotypes A and D, but larger studies are needed to confirm these results.

This study found that parents identified with cryptic NCCAH through genetic testing are mostly asymptomatic but may experience temporary female infertility and require glucocorticoid stress coverage in specific circumstances.

This study found that insulin resistance was significantly associated with PCOS among infertile women with central obesity, highlighting differences in insulin and phenotype severity.

This study found no significant differences in metabolic characteristics between different phenotypes of PCOS or between women with PCOS and healthy controls among reproductive-aged Iranian women.

The researchers reported that among Mediterranean Sicilian women with PCOS, Phenotype B exhibited the most severe metabolic abnormalities, notably obesity and altered glucose metabolism, whereas Phenotype D showed no such issues.

This review analyzes the reported prevalence of polycystic ovary syndrome (PCOS) based on different diagnostic criteria but does not provide new clinical results.

This article is a discussion piece that examines the clinical symptoms of hyperandrogenic women with COVID-19, without reporting new research findings.

Different types of polycystic ovary syndrome show varying levels of insulin resistance, with the 'PHO' type being the most insulin resistant.
