HAIR-AN syndrome is a subset of women with PCOS who present with hyperandrogenism, insulin resistance, acanthosis nigricans, and obesity in the absence of insulin receptor defect. [46] This syndrome is found in 1-3% of hyperandrogenic women. [47] HAIR-AN syndrome is characterized by high levels of post-glucose challenge insulin levels that may reach 300-500 µU/mL. [48]
