To be sure that the effect of Common Sage is NOT due to an inhibition of the effect of the LHRH analogue, the related hormones (testosterone, FSH, LH, free testosterone and SHBG) will be tested at three fixed moments: day of study enrollment, 1 month after study enrollment and at the end of the study. In order to check the level of hemoglobin and cholesterol, every 2 weeks a blood count will be performed. It has been shown that LHRH analogues can induce anemia and hypercholesterolemia. The investigators want to measure a possible effect of Common Sage on both.
