The protocol was designed to address the hypothesis that oral testosterone enanthate plus
dutasteride can suppress the secretion of LH and FSH after four weeks of administration. In
addition, we will compare the gonadotropin suppression mediated by a dose of testosterone
enanthate (400 mg twice daily) that would be expected to maintain the serum testosterone in
the normal range throughout the day, with the same dose (800 mg once daily) administered once
daily. This larger once-daily dose is expected to result in a higher peak and lower trough by
the end of the dosing interval
