Endocrine disruptors have been proposed in the etiology of
polycystic ovary syndrome (PCOS) as they have the potency to interfere with
hormone-sensitivity systems. The aim of this study was to evaluate the levels of
bisphenol A (BPA) and phtalates in adolescents with PCOS. Sixty-two girls with PCOS and 33 controls, age 12-18 years were enrolled in the study. The diagnosis of PCOS was made using modified Rotterdam criteria. Urinary BPA levels were measured using high-performance liquid chromatography. Di-(2-ethylhexyl)-phthalate (
DEHP), the most commonly used
phthalate and mono-(2-ethylhexyl)-phthalate (
MEHP), its main metabolite were measured by using high-performance liquid chromatography. Adolescents with PCOS had markedly increased BPA levels (15.89 μg/g
creatine ± 1.16) when compared with the control group (7.30 μg/g
creatine ± 1.38) (p = .016). In adolescents with PCOS, BPA was significantly correlated with polycystic morphology on ultrasound but not with
obesity androgen levels, or other metabolic parameters. Patients with PCOS (
DEHP: 0.40 ppm ± 0.24,
MEHP: 0.13 ppm ± 0.23) and controls (
DEHP: 0.49 ppm ± 0.27,
MEHP: 0.14 ppm ± 0.3) had similar serum phtalate concentrations (p = .7 and p = .3, respectively). Exposure to specific
endocrine disruptors such as BPA could modify neuroendocrine, reproductive, and metabolic regulation favoring PCOS development in adolescents.
