Abstract
Abstract The endocannabinoid system is postulated to play an important role in the etiology of obesity, insulin resistance, fat distribution and metabolic disorders. Insulin resistance associated with abdominal obesity plays a leading role in the etiology of hyperandrogenism and other clinical features of the polycystic ovary syndrome (PCOS). A total of 174 women 16-38 years old, diagnosed with PCOS according to the Rotterdam criteria are recruited. Control group consisted of 125 healthy women 18-45 years old. Medical history, physical examination, anthropometric parameters and metabolic parameters were carried out. Six CNR1 gene polymorphisms were diagnosed. We observed a significantly three times higher risk of GG genotype in the polymorphism rs12720071 in women with PCOS versus the control group (p = 0.0344, OR = 3.01). A similar, significant 8-fold higher risk (p = 0.0176, OR = 8.81) was demonstrated for genotype CC polymorphism rs806368 associated with PCOS. We observed a 3.6-fold increased risk of hyperandrogenemia (free androgen index – FAI > 7) in patients with GG genotype in the rs12720071 polymorphism and AA genotype in the polymorphism rs1049353 (OR = 2.7). Our study may indicate a role of the endocannabinoid system in the occurrence of a specific hyperandrogenemia phenotype of PCOS.
