Primary Endpoints
Corrected Area Under The Serum Concentration-time Profile From Time 0 to The Last Quantifiable Concentration (AUClast) of Total Testosterone (Part 1).
At -1, -0.5, -0.25, 0 hours predose and at 1, 8, 24, 36, 48, 72, 96, 120, 144, 168, 240, 336 and 480 hours postdose.

The AUClast of total testosterone in Part 1 of the study was observed directly from data. The baseline endogenous testosterone level was the mean of the 4 predose PK samples, an average baseline correction of endogenous total testosterone levels was calculated.

Corrected AUC From Tme 0 Extrapolated to Infinite Time (AUCinf) of Total Testosterone (Part 1).
At -1, -0.5, -0.25, 0 hours predose and at 1, 8, 24, 36, 48, 72, 96, 120, 144, 168, 240, 336 and 480 hours postdose.

The AUCinf of total testosterone in Part 1 of the study was observed directly from data. The baseline endogenous testosterone level was the mean of the 4 predose PK samples, an average baseline correction of endogenous total testosterone levels was calculated.

Corrected Maximum Observed Concentration (Cmax) of Total Testosterone (Part 1).
At -1, -0.5, -0.25, 0 hours predose and at 1, 8, 24, 36, 48, 72, 96, 120, 144, 168, 240, 336 and 480 hours postdose.

The Cmax of total testosterone in Part 1 of the study was observed directly from data. The baseline endogenous testosterone level was the mean of the 4 predose PK samples, an average baseline correction of endogenous total testosterone levels was calculated.

Corrected AUClast of Total Testosterone (Part 2).
At -1, -0.5, -0.25, 0 hours predose and at 1, 8, 24, 36, 48, 72, 96, 120, 144, 168, 240, 336 and 480 hours postdose.

The AUClast of total testosterone in Part 2 of the study was observed directly from data. The baseline endogenous testosterone level was the mean of the 4 predose PK samples, an average baseline correction of endogenous total testosterone levels was calculated.

Corrected AUCinf of Total Testosterone (Part 2).
At -1, -0.5, -0.25, 0 hours predose and at 1, 8, 24, 36, 48, 72, 96, 120, 144, 168, 240, 336 and 480 hours postdose.

The AUCinf of total testosterone in Part 2 of the study was observed directly from data. The baseline endogenous testosterone level was the mean of the 4 predose PK samples, an average baseline correction of endogenous total testosterone levels was calculated.

Corrected Cmax of Total Testosterone (Part 2)
At -1, -0.5, -0.25, 0 hours predose and at 1, 8, 24, 36, 48, 72, 96, 120, 144, 168, 240, 336 and 480 hours postdose.

The Cmax of total testosterone in Part 2 of the study was observed directly from data. The baseline endogenous testosterone level was the mean of the 4 predose PK samples, an average baseline correction of endogenous total testosterone levels was calculated.
