Study: Lack of Sex Interest Successfully Treated by Light
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. Still, it is too early to recommend light therapy for men with low testosterone or low sexual interest. More research is needed, the scientists noted.
However if this treatment can be shown to work in a larger study, then light therapy may offer a way forward. It's a small study, so for the moment, we need to treat it with appropriate caution.
The findings were presented in September at a meeting of the European College of Neuropychopharmacology (ECNP) in Vienna.
