Q | what is a hydrocele?
A | A hydrocele is a collection of fluid in a sac in the scrotum next to the testis (testicle). A smooth protective lining surrounds the normal testis and this makes a small amount of 'lubricating' fluid to allow the testes to move freely. Excess fluid normally drains away into the veins in the scrotum. Occasionally, some fluid accumulates as a hydrocele. Hydroceles are normally painless although large hydroceles may cause discomfort because of their size. Walking or sexual activity may become uncomfortable if you have a very large hydrocele.
If the hydrocele causes no symptoms, one option is simply to leave it alone. If it becomes larger or troublesome, you can have the hydrocele operated on to drain the fluid and prevent a further build up of fluid in the future.
