Hydrocele, a type of swelling in the scrotum, causes no pain or harm. It is very common in newborn babies and they can recover before 1 year old by themselves.


Inflammation or injury within the scrotum may cause hydrocele for men. Infection, including a sexually transmitted infection, could also lead to hydrocele in men.

In most cases, it doesn't need any treatment because it isn't painful or harmful. However, if there is severe situation, make sure to contact the doctor for a thorough examination.


The symptoms of hydrocele include:

  • A painless swelling of one or both testicles
  • Pain (It may increase if the inflammation is severe.)

It is common if patients find that the swollen area is smaller in the morning and larger later in the day. It is also the symptom of hydrocele for adult men.

Often, a hydrocele is not dangerous and doesn't influence fertility, but we still need to be careful because it may cause serious complications including:

  • Infection or tumor
  • Inguinal hernia

Hydrocele and its complications shouldn't be ignored. If you have the symptoms above, make sure to make an appointment with your doctor.
