Study: Lack of Sex Interest Successfully Treated by Light
Light therapy might increase a man’s testosterone levels and, in turn, his sexual satisfaction, according to new research. Past research suggests that sexual interest can wax and wane with the passing of seasons.
A group of Italian scientists wondered whether light therapy may help. They worked with 38 men who were being treated for disorders related to sexual interest and desire. For two weeks, the men received light therapy for a half-hour each morning.
The scientists discovered that the men who received active light treatment saw their testosterone levels increase and their sexual satisfaction improve.
It was unclear why the therapy worked, but the researchers theorized that the light inhibited the pineal gland, thus increasing testosterone production and triggering other hormonal processes.
The findings were presented at a meeting of the European College of Neuropychopharmacology (ECNP) in Vienna.
