    Abstract:
    OBJECTIVE: To explore the relationship of insulin resistance (IR) and adipokines (leptin, adiponectin, RBP4) to anti-Mullerian hormone (AMH) levels in women without polycystic ovary syndrome (PCOS). DESIGN/PATIENTS/MEASUREMENTS: We recruited 120 healthy, reproductive age women without PCOS. An overnight fasting blood draw, anthropometric measurements, analyses of serum levels of AMH, adipokines (leptin, adiponectin and RBP4) and total testosterone, a homeostasis model assessment for insulin resistance (HOMA-IR) and a transvaginal ultrasound scan were performed between the third and fifth day of their spontaneous menstrual cycles. RESULTS: Higher HOMA-IR levels were associated with lower levels of AMH. After adjustment for age, serum AMH levels negatively correlated with insulin, fasting glucose, HOMA-IR and RBP4. However, a positive correlation was identified between serum AMH and adiponectin. A final multiple stepwise linear regression demonstrated that HOMA-IR was independently associated with AMH. CONCLUSION: An independent relationship exists between HOMA-IR and AMH in women without PCOS, possibly due to the effect of abnormal insulin action on AMH secretion by granulosa cells.
