Summary

This is a randomized, open-label trial examining two doses of clomiphene citrate in men with low serum testosterone concentrations (total testosterone (TT) < 300 ng/dl).

Description

This is a randomized, open-label trial examining two doses of clomiphene citrate in men with low serum testosterone concentrations (total testosterone (TT) < 300 ng/dl). The investigators will perform a pharmacokinetic analysis of serum hormone concentrations (TT, LH, FSH, estradiol) after medication administration. Researchers hypothesize that testosterone levels will increase in both groups and this may allow to dose clomiphene citrate so that patients do not need to take the medication daily.
