Why does my 4-year-old son have an erection?

Patient's question:

Patient gender: Female
Patient age: 24
Hello; Erections in children are also a normal phenomenon, so there is no need to be too anxious. If there are also symptoms such as foreskin itching, it is recommended to undergo circumcision as soon as possible.

If there are also symptoms such as foreskin itching, it is recommended to undergo circumcision as soon as possible. I believe everyone knows that prostatitis can cause significant harm to men, so it is important to seek treatment as soon as possible. In daily life, attention should be paid to dietary issues, with a focus on a light diet and avoiding foods. Additionally, it is recommended to follow up regularly when necessary.
