Treatment: 26 weeks of either letrozole or placebo. All patients will start on 1 tablet per week, dose adjustments will be performed if serum testosterone or estradiol are outside the target range. All men will be prescribed a mildly hypocaloric diet.
Endpoints: BMI, body weight, waist circumference, body composition, exercise capacity, serum levels of several hormone markers, glucose tolerance, psychological characteristics.
All patients will be measured 6 times during the study.
