Hormone therapy with a strong lamp
Simply sitting in front of a strong lamp for an hour: endocrinologists from Los Angeles think this can help men raise their testosterone level. They have a few reservations, but their research is promising.
Testosterone
In the dark winter months, however, the melatonin level is higher than normal, and the testosterone level is lower in many animals.
Light makes melatonin disappear. Light activates the enzymes that break down melatonin. How melatonin [I] breaks down is sketched here below. The researchers examined the urine of their subjects and measured the concentration of the metabolite 6-sulfatoxymelatonin [V].

Just after a light therapy session [Onset] the researchers observed a sharp rise in 6-sulfatoxymelatonin [aMT6s] in the urine. Although there seems to be a strong relationship, the researchers are hesitant to conclude that light therapy raises the LH level as a result of melatonin breakdown.
The researchers did not measure whether light therapy also leads to a rise in testosterone. But they do think that, for some groups at least, light therapy may be a suitable form of hormone therapy.
