It is related to the heavy sweating and also rubbing of the inner thighs with the scrotum that is in the groin body area. That is the reason that is much common during the conditions of excessive heat and also the moisture. This typically leads to the rash on scrotum.

Because the temperature is very much hotter than normal, the skin sweats a lot in an attempt to cool itself off. But, due to the fact that it is very humid then the sweat doesn’t disappear from the skin and the epidermis becomes soaked, and the openings for the sweat glands clogs off.

This leads to a buildup of the sweat below the skin. Most often the heat rashes would appear in the covered areas: under the arms or even between the legs that is behind the scrotum. If a person has been squatting down for a period of time, then he can find it also behind the knees.

A cool shower will assist cool the body off. After taking a bath, thoroughly dry off and then let the skin dry itself off before getting dressed once more.

Other names that are given for the male genital dysesthesia are:

  • The burning scrotum syndrome
  • Peno-scroto-dynia or scrotodynia, in which there is no indicated redness.

The rash on scrotum then spreads a short way downwards of the inside part of both thighs.
