While reduced testosterone (also called hypogonadism) can certainly be responsible for low energy and a depressed mood, it isn't the sole cause. In reality, approximately 60% of men diagnosed with low testosterone will have diabetes or metabolic syndrome. Low testosterone might also be associated with cancer, brain-related diseases, obstructive sleep apnea and other hormonal abnormalities. That's the reason why proper analysis by a licensed physician, such as screenings for pituitary tumors, prostate cancer along with other psychiatric conditions, is quite important.
