  • A primary hydrocele causes a painless enlargement in the scrotum on the affected side and is thought to be due to the defective absorption of fluid secreted between the two layers of the tunica vaginalis (investing membrane). (wikipedia.org)
  • A hydrocele feels like a small fluid-filled balloon inside the scrotum. (wikipedia.org)
  • However, as the fluid continues to accumulate and the scrotum further enlarges, more discomfort can be expected. (wikipedia.org)
  • Congenital hydrocele results when the processus vaginalis remains patent, allowing fluid from the peritoneum to accumulate in the scrotum. (wikipedia.org)
