Is it very serious if red spots appear on the testicles?

Patient's question:

The baby is 8 months old, a male baby. At 3 months, red spots appeared on the scrotum, and now there are several patches.

Doctor's answer:

Possible: Diaper rash
This condition refers to localized dermatitis occurring in the diaper area. However, it is not solely caused by diapers; the main reason is prolonged exposure of the skin in the diaper area to urine and fecal matter, combined with the wetness of diapers and the lack of breathability of the diaper material. It may also be caused by irritation from residual soap or cleaning agents on the diaper, as well as the delicate nature of the infant's skin.
Treatment:
1. Change diapers frequently, clean the local skin promptly, and use diapers or disposable diapers with strong water absorption to keep the area dry.
2. Apply zinc oxide ointment externally, or use calamine lotion externally.
