Can the scrotum contract after normal men urinate?

Scrotal contraction is not directly related to urination! The contraction and relaxation of the scrotum is to keep the testis at a constant temperature, which is beneficial to the production of sperm and improve the quality of sperm! If the testicular temperature is too high, the scrotum will relax, which is beneficial to heat dissipation; Testicular (external) temperature is too low, scrotum will shrink, which is beneficial to prevent heat loss! Therefore, when a person has a fever, the scrotum will generally relax; When you feel cold, the scrotum usually contracts! Note: the sexual function of the elderly declines, and the number of scrotal contractions will be less and less.
