This is one of these good, old studies from the 30ies.
They applied light to different body parts of depressed individuals and measured androsterone output afterwards.
The light contained UV- and infrared light, similarly to sunlight:
"...the spectrum of this lamp consists of 52% infrared, 20% luminous and 28% ultraviolet rays."
Irradiating the chest increased androsterone output by about 120%:
"After 5 irradiations of the chest, the hormone output was raised to 155 i.u. per liter, that
is, an increase of 120%."
Irradiating the testicles yielded a 200% increase:
"The next series of irradiation was applied solely to the genital region and its immediate vicinity, the remainder of the body being carefully protected from all rays. After 5 irradiations during 6 days, the androsterone excretion
was raised from 70 to 205 i.u., nearly 200%"
In both applications the maximum level was reached after about 5 days, no further increase was observed. But after cessation the androsterone legel returned to baseline in a few days.
What I find very interesting is that even once weekly application had similar results, although the peak was reached only after 12 applications:
"A case in which irradiations were applied twice weekly at first and later only once weekly did
not show the peak after 5 irradiations, but rather a continuous rise during the whole period of treatment which reached the number of 12 irradiations."
