Summary
In this case-controlled, observational study, 24 subjects will participate in a 12-hour blood collection with a single blood draw at +24 hours. 12 men will have low testosterone levels (hypogonadism) and 12 men will have normal testosterone levels. Blood samples will be drawn every 2 hours and later analyzed for total testosterone and calculated free testosterone. The primary objective of this study is to assess the degree of diurnal variation in men with testosterone deficiency.
