Brief Summary
AIMS To study the effects of the decrease in iron tissue depots after scheduled bloodletting on insulin sensitivity, carbohydrate metabolism, classic and non-classic cardiovascular risk factors in patients with functional hyperandrogenism (polycystic ovary syndrome \& idiopathic hyperandrogenism) on standard treatment with combined oral contraceptives (COC) according to usual clinical practice. METHODOLOGY Open label, controlled, parallel, prospective study of 12 months of duration, with 2 randomized arms of follow-up: i) Intervention Group: Patients with functional hyperandrogenism on standard COC treatment randomly allocated to perform scheduled phlebotomies from the third month of treatment to the end of the study (3 times with a 3-month interval between them). ii) Control Group: Patients with functional hyperandrogenism on standard COC treatment randomly allocated to follow-up without bloodletting. The whole group of patients will undergo a comprehensive anthropometric and hormonal assessment, evaluation of classic cardiovascular risk factors (insulin sensitivity and carbohydrate metabolism after a standard oral glucose test- 75 g), lipid profile, ambulatory and office blood pressure monitoring, proinflammatory profile, oxidative stress status, autonomic function assessment, and iron-related metabolism parameters at baseline, after 3-month COC treatment and after reduction of iron tissue depots plus OC in the Intervention Group of patients, and throughout follow-up under treatment with COC in the Control Group of patients. If a significant relationship between circulating hepcidin levels and elevated ferritin concentrations is observed, a study of the potential influence of mutations/polymorphic variants of hepcidin gene on ferritin values will be performed as well.

Study Arms (2)
Intervention
EXPERIMENTALPremenopausal women with functional hyperandrogenism under combined oral contraceptive pill qd as usual clinical practice who will undergo a scheduled standard phlebotomy every 3 months from month 3 to 12 of follow-up.
Control
ACTIVE COMPARATORPremenopausal women with functional hyperandrogenism under standard combined oral contraceptive pill qd as usual clinical practice.
Interventions
Scheduled standard phlebotomy every three months from month 3 to 12 of follow-up.
35 mcg ethinylestradiol qd for 21 days per month as usual clinical practice.
2 mg cyproterone acetate qd for 21 days per month as usual clinical practice.
