Effect of testosterone cypionate on postexercise ST segment depression.
A r and omised double blind study was carried out with 50 men who had ST segment depression of 0.1 mV or more after a modified two-step exercise test . Rate and duration of exercise were the same for the last of each subject 's several pretreatment tests as for his tests after 4 and 8 weeks of treatment with placebo or testosterone cypionate , 200 mg , intramuscularly weekly . The sum of ST segment depression in leads II , V4 , V5 , and V6 taken immediately , and 2 , 4 , and 6 minutes after exercise did not change significantly after 4 or 8 weeks of placebo treatment , but did decrease by 32 per cent ( P less than 0.0001 ) and 51 per cent ( P less than 0.0001 ) after 4 and 8 weeks , respectively , of testosterone cypionate treatment . The mechanism by which testosterone cypionate treatment results in lessened postexercise ST segment depression is not established
