Patient's question:

Here is the English translation of the provided text, with the line breaks preserved as instructed:
Used in the shower, rinsing the scrotum, anus, waist, and neck with hot water—is this equivalent to a certain massage and heat application? Is it okay to rinse each area for 5 minutes? Will it bring dampness or other harm to the body?

Doctor's answer:

All parts can be rinsed with hot water, except the scrotum for men, which should not be rinsed with hot water for long periods.
Medical advice: The scrotum contains the testicles, which produce sperm. The temperature of the testicles is lower than the normal body temperature. If the temperature is too high, it can affect male fertility. For example, men born with undescended testicles (where the testicles do not descend into the scrotum after birth) are considered to have infertility issues.
