Many hydroceles resolve without treatment. Surgery for hydrocele (hydrocelectomy) usually has excellent results, but recurrence of the condition can occur.
Because the condition develops before birth, hydroceles cannot be prevented in newborn infants. However, proper prenatal care can help prevent premature births and reduce the risk for hydroceles in baby boys.
Adult males can take steps to protect the genital area from injury—for example, wearing a protective athletic cup and following safety rules when playing sports.
Healthy lifestyle choices, such as exercising and eating right, and avoiding sexually transmitted infections (STDs) are also recommended to help prevent hydrocele.
