°data at 18 months of leuprorelin administration.

^∧data in peer-protocol population (n = 37 patients who had received all doses of triptorelin 11.25 and without no major protocol violation).

^§LH peak below 3.0 IU/L was documented at 15, 18, and 21 months of followup. At month 24, 1 patient showed a leak peak at 3.0 IU/L.

*20/28 (71%) required treatment injections at 6–10 weekly intervals.

°°data were confirmed in the 12–24 months of followup [20].

^∧∧using the lower cutoff value of 2.0 IU/L [18], the percentage of patients with optimal suppression did not change.
