Note: if available, another testosterone analysis performed during the period covered by the treatment with this formulation will also be collected to confirm that castration status was maintained in the participant; Note: A noncastrated participant is defined as a participant who was not receiving any testosterone-blocking treatment at the time of the first injection with the 6-month triptorelin formulation but had history of previous ADT agents.
