Its weightusually ranges from five to six drams, or twenty to twenty-four grams. Its sur-face is formed by a smooth, white investment of dense fibrous tissue—the tunicaalbuginea. The hilum of the testicle is at the posterior border of that organ, and is theplace where the blood vessels, nerves, lymphatics, and seminiferous tubules leaveor enter the testicle.
