Is the testosterone decline observed with aging related to changes associated with the sleep pattern of aging?
Yes, at least in part, it does. Aging is associated with less time in overall sleep and less time in SWS. In older men, LH pulses show lower amplitude but increased frequency
Not all the parameters have been considered and, therefore, could be confounders to the data associated with testosterone changes in aging. The sleep-related testosterone rise is still seen in older men, although the magnitude is less, and it is no longer associated with duration of the first NREM period.
