Aging men's testosterone decline is largely due to the fact that older men sleep less well than younger men. At least that's the conclusion of researchers at the National University of Singapore who studied 531 Chinese men aged between 29 and 72. The researchers measured the amount of testosterone in the men's blood in the mornings, and asked the men about their sex lives and their sleep.
Clearly, sleep patterns, possibly leading to a sleep study, should be investigated during a man's initial workup for possible hypogonadism.

- These men were remarkably healthy, as the attached table shows, and there is a relationship between sleep and testosterone levels.
- Men who slept less than 4 hours in a 24-hour period had about 60 percent less TotalT and 55 percent less BioT than men who slept longer than 8 hours. Extrapolating this you arrive at the following estimate: one hour extra sleep may raise your testosterone level by 12-15 percent.
