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.

We evaluated the efficacy of the tamoxifen treatment in 37 patients with pubertal gynecomastia. All had distinct, easily palpable breast swellings with a diameter of over three cm. Pain, tenderness, and swelling associated with gynecomastia were reported by six patients. Eight of the patients were obese. One patient also suffered from varicocele. Pain and size reduction was seen in all patients with tamoxifen treatment. No long-term side effects of tamoxifen were observed. The dose of tamoxifen was increased in three patients due to poor response. Two of the treatment group had recurrence problem at follow-up. We did not need to refer any patient to surgery. Tamoxifen treatment is relatively non-toxic, may be beneficial and we think it should be considered for pubertal gynecomastia.
