Is temperature shock concept is pure hypothesis? NO, it is not.

I (author) have tested the effect of temperature shock several times and it really effect pee activity (feeling uncomfortable at prostate area) for several days. I  handled this temperature shock problem with local herb which has dieuretic benefit.

Now I do not want to try it anymore and it is better to use the cheapest way to prevent prostate problem which is only: WARM WATER (around body temperature at 37 degree celcius) for cleaning body and bathing.
