An AE is defined as any untoward medical occurrence in a patient or clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. AEs related to sexual function are defined as: altered (decreased) libido, impotence, and ejaculation disorders.

An AE is defined as any untoward medical occurrence in a participant temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An AE can therefore be any unfavorable and unintended sign(including an abnormal laboratory finding), symptom, or disease(new or exacerbated) temporally associated with the use of a medicinal product. A SAE is defined as any untoward medical occurrence that, at any dose, results in death, is life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, a congenital anomaly/birth defect, important medical events that jeopardize the participants or may require medical or surgical intervention to prevent one of the other outcomes listed in the above definition, drug-induced liver injury, breast cancer in male participants, prostate cancer, spontaneous abortion in female partner of male participants

An AE is considered drug-related if the relationship variable indicates so, or if the variable value is missing. Any AE with a start date on or after the treatment start date and on or before the last dose of treatment is considered on-treatment (treatment-emergent). This includes an AE with a missing onset date. Any AE which occurred, in the investigator's judgement and is possibly related to suicidality, is defined as possible suicidality-related adverse event (PSRAE). Suicidality was assessed by using the columbia-suicide severity rating scale (C-SSRS) as determined by the investigator. The C-SSRS captures occurrence, severity, and frequency of suicide-related thoughts and behaviors.

A qualitative breast examination was performed at Baseline (Week 0), at the Week 26 Visit and at the Week 52 Visit (and at the early withdrawal visit, if applicable). Participants were assessed for presence (reported as yes) and absence (reported as no) of palpable breast tissue (PBT) or nipple tenderness (NT) and/or clinically significant (CS) PBT or NT at Baseline (BL), at each scheduled Post-BL assessment. Change from BL in breast examination results included the number of participants with change from 'no (N)' at BL to 'yes (Y)' at any Post-BL assessment for the presence of PBT or NT, and the number of participants with change from N at BL in CS to Y at any Post-BL assessment in CS for PBT and for NT. BL value of an assessment is defined as the latest assessment on or before the BL date (latest non-missing value of either the treatment start date or the randomization date).

Blood samples were collected for the measurement of prostate-specific antigen at Baseline, Week 26 and Week 52 visits and the early withdrawal visit where applicable. Change from Baseline in the prostate-specific antigen value is summarized for each post-Baseline assessment as well as for the final assessment (the last post-Baseline value in the study \[final value\]).

Blood samples for the assessment of the indicated laboratory parameters were taken at the Baseline, Week 26 and Week 52 visits and the early withdrawal visit where applicable. The laboratory parameters included ALP, ALT, AST, total bilirubin, total protein, sodium, potassium, albumin, glucose, creatinine, urea/BUN, hemoglobin, hematocrit, red blood cell (RBC) count, platelet count, white blood cell (WBC) count, and prostate-specific antigen (PSA). A laboratory value (LV) that is within the normal range is considered normal. A LV that is above the upper limit of the normal range is considered high abnormal. A LV that is below the lower limit of the normal range is considered low abnormal. Number of participants with any LV shifts from BL at any time post-BL are presented for, normal at BL to abnormal; normal at BL to high; normal at BL to low; normal or low at BL to high; normal or high at BL to low.

The C-SSRS captures occurrence, severity, and frequency of suicide-related thoughts and behaviors. The number of participants answering yes/no responses to questions about suicidal ideation (Question \[Que\] 1 and Que 2) at Baseline and post-Baseline (since last visit) and suicidal behaviors (Que 6 - Que 10) at post-Baseline (since last visit) are presented. Questions included the presence (yes) or absence (no) of the following: Que 1 - a wish to be dead; Que 2 - nonspecific (NS) active suicidal thoughts; Que 6 - preparatory acts or behavior; Que 7 - aborted attempt; Que 8 - interrupted attempt (int. att.); Que 9 - non-fatal actual suicide attempt; Que 10 - completed suicide and non-suicidal self-injurious behavior. Final assessment (FA) is the last post-Baseline measurement during the study.

Percent change from baseline was calculated as the prostate volume at Month 6 minus the volume at baseline, divided by the prostate volume at baseline and multiplied by 100. Prostate volume was measured by transrectal ultrasound.

The Macrophotographic hair count method marks a 1-inch diameter circular area at the anterior leading edge of the vertex thinning area and then photographed. The photographs are enlarged and converted into dot maps and the dot maps are converted into total hair counts by means of personal computer-based scanners and imaging software.

Study biopsies consisted of 10 biopsy samples (cores) in a pre-defined pattern. Biopsies were read at the central pathology laboratory (CPL, which processed the majority, 94%, of biopsies). Biopsy cases that were positive for prostate cancer or precancerous lesions (high-grade prostatic intraepithelial neoplasia\[HGPIN\] or typical small acinar proliferation \[ASAP\]) and prostate surgeries were reviewed by the lead pathologist.

Study biopsies (biop.) consisted of 10 biop. samples (cores) in a pre-defined pattern and were read at the central pathology laboratory. Biop. cases that were positive for prostate cancer or precancerous lesions (HGPIN or ASAP) and prostate surgeries were reviewed by the lead pathologist. Participants included in the risk sets at Years 1-2 and Years 3-4 included those with a positive biop. at Years 1-2 or a biop. after Months 18-24, and those with a positive biop. at Years 3-4 or a biop. after Month 42, respectively. Overall included participants with a positive biop. or biop. after Month 42.
