Relationship in morning total testosterone concentration to average total testosterone concentration for the enclomiphene citrate 25 mg group. An example of the relationship between a morning total testosterone value and the average total testosterone value over a 24-h period is given. Subjects were all men with AIHH who had been treated for 6 weeks with enclomiphene citrate and the pharmacodynamics of their total testosterone was determined (pharmacodynamic study part 2); thus, they were assessed for total testosterone every hour for 24 h and the mean hourly total testosterone was determined. TT, total testosterone.
