The testicles first form in the abdomen of the male fetus. Just before birth, the testicles move down into the scrotum. As this happens, fluid from the abdomen may pass into the scrotum. This fluid collects in a small sac within the scrotum and appears as a small swelling or bulge there.
This bulge is called a hydrocele (non-communicating type). It's painless and causes no harm. In most cases the fluid is absorbed during the first 1 to 2 years of age. Sometimes it stays beyond 2 years of age and needs to be corrected with surgery.
A small hydrocele will not interfere in any way with normal activity. There are no special precautions that need to be taken. You can watch the area as you provide regular daily care. Call your child's healthcare provider right away if you notice any changes..
Follow up with your healthcare provider, or as advised. This is to be sure the hydrocele is shrinking as expected.
When to seek medical advice
Call your healthcare provider right away if any of these occur:
Pain, redness or tenderness in the hydrocele
A new bulge in the groin that appears just above the thigh crease or in the scrotum
Changes in size of the hydrocele. This can mean that is gets smaller, then larger, then smaller. This can also mean that it gets larger and stays larger.
