Swollen scrotum. Is it dangerous? Any home remedy? Effect on sexual life.

See answer. There are many causes of scrotal swelling (medical conditions, infections, anatomical abnormalities, tumors, etc) and it is important to know the cause of your swelling. In a young male, hydrocele (fluid around testicle) would be a common, generally non-painful swelling. Testicular cancer and varicocele would be other causes of relatively non-painful swelling. Epididymitis causes painful swelling.
