Study Endpoints

Primary Endpoints

Percentage of Participants With Suppression of Peak Stimulated Luteinizing Hormone (<4 mIU/mL) From Month 2 Through Month 6
Month 2 through 6

Percentage of participants with suppression of peak stimulated luteinizing hormone that was measured after a gonadotropin-releasing hormone agonist (GnRHa) stimulation test at Month (Mo) 2, 3, and 6. The analysis was performed according to a life table method. Subjects who withdrew without peak-stimulated luteinizing hormone \>= 4 mIU/mL were censored at their last measurement of peak-stimulated luteinizing hormone.
