The main reason for sweating under the testicles in men is that the testicular area is in close contact with the inner thighs, and friction can easily lead to sweating, breeding bacteria and other local infections. It is recommended to wear breathable, cotton underwear and keep the area clean and dry. Washing with warm water every morning and evening can achieve a preventive effect. If necessary, local erythromycin ointment or clotrimazole ointment can be selected for topical application. The normal course of the disease takes 1-2 weeks and does not require too much stress. During the treatment period, it is best to eat lightly and not to have intercourse, which can easily lead to cross-infection phenomenon.
