Context: Bisphenol A (BPA) is an environmental endocrine disruptor that has been linked to many reproductive disorders in animal models and humans. One such disorder is polycystic ovary syndrome (PCOS), which has been correlated with increased BPA levels in adult women. However, little is known about the role of serum BPA in adolescents with PCOS and its correlation with the metabolic profile.

Objectives: To measure BPA levels in adolescent with PCOS as compared to a body mass index (BMI)-matched control group. To correlate serum BPA levels with disease severity, as measured by biochemical and radiologic features.

Design: A retrospective chart review of clinical, biochemical, and ultrasonographic data in adolescents with PCOS and controls. Serum BPA was measured and compared between groups and correlated with biochemical (testosterone, insulin resistance) and ovarian ultrasound findings.

Setting: Urban tertiary academic medical center.

Participants: Study groups included 15 overweight/obese adolescent females with PCOS (mean age 15.27 years, mean BMI 32.84) and 14 BMI-matched female controls (mean age 14.1 years, mean BMI 31).

Results: Biochemical data showed a mean free testosterone of 7.06 pg/mL and mean LH:FSH ratio of 1.93 in the PCOS group as compared to mean testosterone of 4.51 pg/mL and mean LH:FSH ratio of 1.12 in the control group (P=0.08 and 0.012, respectively). The index of insulin resistance (HOMA-IR) was 1.65 in the PCOS group and 1.82 in the control group (P=0.75). Serum BPA levels were 0.624 +/- 1.29 ng/mL in the PCOS group versus 0.28 +/- 0.11 ng/mL in controls (P=0.325). No correlation was found between serum BPA levels and biochemical and radiologic markers of PCOS severity. 

Conclusions: The results of this exploratory study pose many interesting questions about BPA exposure in adolescents. Although the results are not statistically significant, both adult studies and animal models have shown a strong correlation between serum BPA and severity of PCOS. The weaker relationship in adolescents may be explained in part by shorter duration of exposure to BPA in years. Further studies are warranted to clarify the correlation of PCOS and the endocrine disruptor BPA in a larger setting.
