The relaxation response also seems to increase the available level of serotonin, which is a chemical in the body that positively affects emotions and thoughts.

The most common cause of scrotal itch is skin lesions such as psoriasis and eczema, when people can scratch so intensely that they make the skin bleed. But these conditions are of course visible and you say there is no rash, so we must think again.
What causes cysts on the scrotal skin? Q. I am 33 years old. For the past 6-7 years, I have cyst-like growths (around four in number) on the skin of the testicles. I read somewhere that this is harmless, so I ignored them till now (as there is no pain). But now one of them has grown a little bigger (around the size of a pea).
