Testosterone has a circadian rhythm that causes the lowest level in the evening and levels to rise during sleep. If sleep is interrupted levels won’t rise as quickly. Low testosterone also decreases sodium reabsorption by the kidneys. Extra urination could be the result of the body trying to replace the sodium it is less effectively holding on to due to decreased sodium reabsorption. Testosterone is of course a more significant factor in males corresponding to the finding of higher prevalence in males.
