Which condition is typically characterized by excessive fluid buildup in the scrotum?

The condition characterized by excessive fluid buildup in the scrotum is hydrocele. A hydrocele occurs when fluid accumulates in the thin sheath surrounding a testicle, leading to swelling in the scrotum. This condition is often painless and may be noticed as a bulge or increase in size of the scrotum. Hydroceles are common in newborns and often resolve on their own; however, they can also occur in older males due to various factors such as injury, inflammation, or infection.

Other conditions mentioned in the options have different characteristics and implications. Cryptorchidism refers to undescended testicles, testicular torsion involves the twisting of the spermatic cord affecting blood flow, and a scrotal hernia is when tissue protrudes through a weak spot in the muscles of the scrotum, none of which primarily involve fluid accumulation.
