The percentage of patients that do not reach testosterone castration levels below 50ng/dL is negligible. Setting the castration threshold on 20ng/dL is more reliable, as seen that more patients do not reach this threshold [16–18,29]. 1, 3M: depot formulation of respectively 1 or 3 months; L: leuprolide.

About 7% of patients receiving LHRH agonists will have a breakthrough response, if the castration level is set at 50ng/dL [21–23]. 3M: 3 month depot formulation; G: goserelin; L: leuprolide.

If the castration level is set at 50ng/dL, about 6% of patients will have an acute-on-chronic response [6,21,24]. 1, 3M: depot formulation of respectively 1 or 3 months; G: goserelin; L: leuprolide.

Median serum testosterone level remains below 20ng/dL for up to 6 months, after the administration of a 3-month depot LHRH agonist [26].
