Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Two subjects were deemed ineligible for the study. One subject was lost to follow up before being assigned to Group 1 or Group 2.

Reporting Groups
  Description
Group 1 (FSH) Patients in Group 1 will receive subcutaneous FSH injections daily, titrated to achieve a FSH level of 4-8 IU/L, for 4 months. Patients will then receive GnRH therapy for 18 months. GnRH will be administered via a portable infusion pump at 2-hour intervals to stimulate endogenous LH secretion.
Group 2 (GnRH) Patients in Group 2 will receive GnRH therapy for 18 months. GnRH will be administered via a portable infusion pump at 2-hour intervals to stimulate endogenous LH secretion. Patients in Group 2 will not receive prior FSH administration.
