Recruitment & Eligibility

Status: ot Recruiting

Sex: Not specified

Target Recruitment: 520

Inclusion Criteria

1. Male patients aged at least 40 years old
2. An early morning total testosterone level less than or equal to 11 nmol/L or calculated free testosterone levels less than or equal to 255 pmol/L, at least two separate timepoints, (between 08.00 - 10.00), at least one week apart.
3. At least two symptoms of hypogonadism (e.g. decreased libido, erectile function, lean body mass or muscle mass; decrease in bone mineral density resulting in osteoporosis; depression, irritability and diminution of mental acuity; fatigue; and vasomotor symptoms, such as hot flushes)
4. Metabolic syndrome as defined by the International Diabetes Federation (IDF):
Central obesity (defined as a waist circumference greater than or equal to 94 cm for Europid men, with ethnicity specific values for other groups) and any two of the following four factors:
(a) raised TG level: greater than or equal to 150 mg/dL (greater than or equal to 1.7 mmol/L), or specific treatment for this lipid abnormality
(b) reduced HDL cholesterol: less than 40 mg/dL (less than 1.03 mmol/L in males, or specific treatment for this lipid abnormality
(c) raised blood pressure: systolic BP greater than or equal to 130 mmHg or diastolic BP greater than or equal to 85 mmHg, or treatment of previously diagnosed hypertension
(d) raised fasting plasma glucose (FPG) greater than or equal to 100 mg/dL (greater than or equal to 5.6 mmol/L), or previously diagnosed type 2 diabetes mellitus. If above 100 mg/dL or 5.6 mmol/L, an oral glucose tolerance test (OGTT) is strongly recommended but is not necessary to define presence of the syndrome.
and/or type 2 diabetes mellitus as defined by:
fasting plasma glucose (FPG) greater than or equal to 126 mg/dL (greater than or equal to 7.0 mmol/L) on two occasions or random glucose greater than or equal to 200 mg/dL (greater than or equal to 11.1 mmol/L) and classic symptoms of type 2 diabetes mellitus (polyuria, polydipsia, polyphagia, with / without weight loss) or previously diagnosed type 2 diabetes mellitus.
