Now please note: this is not a joke.
I understand that Testosterone is responsible for the darkening of the skin of the male sex organs during puberty. However, before Christmas, I began to take hot baths. I then did some research and figured it was not a good idea. Now it could be just a coincidence (or maybe even just from switching from regular showers to regular baths that I find myself having the opportunity to navel-gaze!) I notice that some skin on my penis has gone lighter than the rest of the skin on the penis, and that the scrotum is paler than I remember it. Now that is not very objective, is it, yet I was wondering is there any link between T levels and the pigmentation of the male sex organs in adulthood, as in, if a man suffered a decrease in T, might his sex organs respond by becoming paler than they were before? Is there any science to back up such a notion?
