研究概览
简要总结
The study is designed to answer the following questions:
- Is there any difference between the compositions of the HDL cholesterol subpopulations of patients with hypogonadism and the healthy controls.
- What is the effect of testosterone replacement therapy on the distributions of HDL subgroups.
- Is there any difference between the effects of the two different testosteron replacement regiments
详细描述
This study has two designs:
- The case control design to search for the difference between the HDL subgroups and the other metabolic parameters between the healthy subjects and the patients with hypogonadism
- The follow-up study to search for the effects of two different testosterone replacement regiments.

结局指标
主要结局
Changes in the HDL cholesterol levels and the HDL subgroups
时间窗: 6 months
The HDL subfractions were measured by polyethylene glycol (PEG) precipitation technique. Two different reagents were prepared in different PEG concentrations and pH values. The supernatant of the solution precipitated with reagent A contained total HDL cholesterol while the supernatant of the solution precipitated with reagent B, contained only the HDL3 subclass. The cholesterol was then quantified by enzymatic with CHOD-PAP reagent (Olympus Diagnostics GmbH, Hamburg, Germany). HDL2 cholesterol was measured by calculating the difference between total HDL and the HDL3 subclass.
