Abstract

Abstract Objective: To determine whether 3-month GnRH analogue (GnRH-a) administration to hyperandrogenic anovulatory patients and healthy women affects glucose utilization or endogenous glucose production (EGP) in the postabsorptive state and during variable hyperglycemic–hyperinsulinemic infusions. Design: Prospective, nonrandomized study. Setting: Academic research environment. Patient(s): Twelve hyperandrogenic anovulatory patients and 11 healthy women matched by body mass index and waist to hip circumference ratio. Intervention(s): Variable hyperglycemic–hyperinsulinemic infusions replicated physiological increases in circulating glucose and insulin levels before and after 3-month GnRH-a administration. Main outcome measure(s): Glucose utilization and EGP. Result(s): In the postabsorptive state, plasma glucose and insulin levels, glucose utilization, and EGP were similar in hyperandrogenic patients and healthy women. During variable hyperglycemic–hyperinsulinemic infusions, glucose use increased and EGP decreased to similar degrees in both groups of women. Three-month GnRH-a administration to hyperandrogenic patients and healthy women did not affect plasma glucose and insulin levels, glucose utilization and EGP in the postabsorptive state, or glucose utilization and EGP during variable hyperglycemic–hyperinsulinemic infusions. Conclusion(s): Glucose use and EGP in the postabsorptive state and during variable hyperglycemic–hyperinsulinemic infusions are similar in hyperandrogenic anovulatory patients and healthy women of similar body fat distribution and are unaffected by 3-month GnRH-a administration.
