Patient's question:

17 years old this year, left testicle 3.5mm, the doctor said to have surgery, I'm scared, want to take medicine

Doctor's answer:

Hello, it's hydrocele, right? Hydrocele of the testis often resolves spontaneously before the age of two, so treatment is not urgent. If it does not disappear after the age of two, then puncture and aspiration should be performed. Most of the time, it does not recur after aspiration.
