In a normal adult, there should be no odor in the perineal area. If there is an odor, it is likely to be a bacterial infection or a fungal infection. Because the inner thighs and scrotum are in close contact with the skin, and it is easy to cause moisture and sweating, these are the favorite parts for bacteria and fungi to grow. If you don’t pay attention to your personal hygiene, it will easily lead to infection and odor. It is recommended that you pay attention to your personal hygiene, wash your perineal area 2-3 times a day, wipe it clean with a dry towel, wear cotton breathable underwear, and observe to see if you can get better, and if necessary, you can choose to use erythromycin ointment, or miconazole nitrate ointment, clotrimazole ointment, etc. for external use. The effect is relatively good. Generally, the normal course of the disease takes two weeks.
