Polycystic ovary syndrome affects a striking 9-18% of Australian reproductive aged women and has been associated with a number of metabolic abnormalities.

Given the strong correlation between metabolic abnormalities and increased sympathetic activity, we hypothesise that reducing this activity using medication (moxonidine) can help improve the metabolic abnormalities, and therefore improve outcomes in polycystic ovary syndrome.

Further study details as provided by Baker IDI Heart and Diabetes Institute:

Primary Outcome Measures:
  • Microneurography [ Time Frame: 3 months ] [ Designated as safety issue: No ]
    Microneurography is a technique developed to measure the sympathetic activitiy directly from the peroneal nerve. Microneurography will be performed at baseline visit and at 3 months follow up visit.

Secondary Outcome Measures:
  • Blood biochemistry measurement [ Time Frame: 3 months ] [ Designated as safety issue: No ]
    To assess the metabolic function of the participants we will be drawing fasting blood samples for biochemical analysis. These test will be performed at baseline and 3 months follow up visit

  • Oral glucose tolerance test [ Time Frame: 3 months ] [ Designated as safety issue: No ]
    A standard 75g glucose tolerance test will be performed. Venous blood will be taken before and 2 hours after the glucose drink was given.
