We visited the Jacksonville Zoo with our four children (ages 6-13) and had a very nice time. The zoo is small enough to enjoy in a partial day which we prefer as we'd rather not leave exhausted. We also took advantage of our reciprocal membership (from our home zoo) and received discounted admission.
A hydrocele is a collection of fluid surrounding the testicle. It is located within the outer layer of the testicle called the tunica vaginalis. Hydroceles can also develop due to inflammation or injury within the scrotum. These sometimes resolve over a few months but many remain and require medical attention.
A hydrocele can reach quite a large size (500 ml of fluid) without causing any pain. In some cases a man with a hydrocele may feel that he has to pass urine frequently, or urinating may be uncomfortable.
