Androgen excess and triggering factors as the cause of PCOS. In some patients (*) androgen excess is severe enough to result in PCOS even in the absence of triggering environmental factors. At the other extreme (†), a very mild defect in androgen secretion is amplified by the coexistence of abdominal adiposity, obesity and/or insulin resistance. Between the two extremes, there is a spectrum in the severity of the primary defect in androgen secretion, explaining the heterogeneity of PCOS patients with regards to the pres- ence of obesity and metabolic comorbidities. However, all patients share a primary defect in androgen secretion. (reproduced from Escobar Morreale and San Millán, Trend Endocrinol Met, 18, 266-272 (2007), with permission of Elsevier BV).
