Study Arms (2)

Naive patients - ARM 1

EXPERIMENTAL

TRT naïve subjects, Tanner Stage of 0, receiving Testosterone Nasal Gel \[Natesto\] - Single dose of 5.5 mg Natesto on Day 1 and a single dose of 11 mg Natesto on Day 2

Drug: Testosterone Nasal Gel [Natesto]

Non-naive patients - ARM 2

EXPERIMENTAL

TRT non-naïve subjects (have had prior testosterone treatment), Tanner Stage \>/= 3, receiving Testosterone Nasal Gel \[Natesto\] - Single dose of 11 mg Natesto on Day 1. On Day 2, 11 mg dose of Natesto in the morning and 11 mg dose of Natesto 12 hours later

Drug: Testosterone Nasal Gel [Natesto]

Interventions

nasal gel containing 4.5% w/w testosterone
