- Primary Outcome Measures
Name Time Method Change From Baseline in Blood Luteinizing Hormone (LH) Level at Week 48 Baseline (Day 0) to Week 48 A blood sample was collected at Baseline and Week 48 for the assessment of the hormone parameter LH measured in milli-International Units per milliliter (mIU/mL). A positive change from Baseline indicates improvement.
Change From Baseline in Blood Dihydrotestosterone (DHT) Level at Week 48 Baseline (Day 0) to Week 48 A blood sample was collected at Baseline and Week 48 for the assessment of the hormone parameter DHT. A positive change from Baseline indicates improvement.
Change From Baseline in Body Strength (Leg Press Weight) at Week 48 Baseline (Day 0) to Week 48 Body strength was assessed from maximum chest and leg press weight achieved, using an inclined plane leg press and vertical chest press. A positive change from Baseline indicates improvement.
Change From Baseline in Lean Body Mass (LBM) at Week 48 Baseline (Day 0) to Week 48 LBM was assessed using dual-energy X-ray absorptiometry (DXA). A positive change from Baseline indicates improvement.
Change From Baseline in Body Strength (Chest Press Weight) at Week 48 Baseline (Day 0) to Week 48 Body strength was assessed from maximum chest and leg press weight achieved, using an inclined plane leg press and vertical chest press. A positive change from Baseline indicates improvement.
Change From Baseline in Blood Estradiol (E2) Level at Week 48 Baseline (Day 0) to Week 48 A blood sample was collected at Baseline and Week 48 for the assessment of the hormone parameter E2. A positive change from Baseline indicates improvement.
Change From Baseline in Ratio of Testosterone: Estradiol (T:E2) at Week 48 Baseline (Day 0) to Week 48 The T:E2 ratio was calculated as the value of T/value of E2 using the same units. A positive change from Baseline indicates improvement.

Change From Baseline in Blood Quantose-Insulin Resistance (IR) Score at Week 48 Baseline (Day 0) to Week 48 Quantose-IR is a laboratory-developed test that assesses insulin resistance. Quantose-IR score is based on a linear regression algorithm utilizing the quantitative measures (natural log transformed) of alpha-hydroxybutyrate, oleate, linoleoylglycerophosphocholine and insulin and was designed to estimate the natural log of insulin-induced glucose infusion rate normalized by whole body mass. The algorithm score is converted to the Quantose-IR score within a range of 1-120 by an arithmetic calculation where higher scores denote greater insulin resistance. A negative change from Baseline indicates improvement.
Change From Baseline in Ratio of Dihydrotestosterone: Testosterone (DHT:T) at Week 48 Baseline (Day 0) to Week 48 The DHT:T ratio was calculated as the value of DHT/value of T using the same units. A negative change from Baseline indicates improvement.
Change From Baseline in Homeostatic Model of Assessment - Insulin Resistance (HOMA-IR) at Week 48 Baseline (Day 0) to Week 48 The HOMA-IR is the product of the blood Glucose and Insulin levels, divided by a constant. HOMA-IR is expressed as the following: HOMA-IR = fasting serum insulin (μU/mL) × fasting plasma glucose (mmol/L)/22.5. A negative change from Baseline indicates improvement.
Change From Baseline in Body Mass Index (BMI) at Week 48 Baseline (Day 0) to Week 48 BMI is calculated as weight (kg)/height(cm\^2). A negative change from Baseline indicates improvement.
Change From Baseline in Weight at Week 48 Baseline (Day 0) to Week 48 A negative change from Baseline indicates improvement.
