[Latin] One of the pair of glands contained in the scrotum, which secrete the semen. The t. is covered successively by a double-layered serous sac (tunica vaginalis) which was originally a part of the peritoneum; the tunica albuginea, composed of dense fibrous connective tissue; and the tunica vasculosa, composed of a network of vessels united by delicate connective tissue. The space within the tunica albuginea is divided into two large compartments by the mediastinum testis, derived from this tunic, and into many small compartments by septa derived from the mediastinum; and these compartments enclose the conical lobules of the t., each consisting of one or more convoluted tubes (seminiferous tubules) which unite to form 20 or 30 straight tubes (vasa recta). The vasa recta, after forming an anastomosing network (rete testis) in the mediastinum, terminate in 12 or 20 ducts (vasa efferentia) which leave the t. and on top of it constitute the epididymis; the globus major of the latter being formed of the convoluted ducts themselves, the globus minor of a single convoluted tube into which these ducts all empty. This duct is continued into the vas deferens. The t. is originally contained in the abdominal cavity, but descends into the scrotum during the latter part of fetal life (Descent of the t’s).

The sexual gland of the male.

Any structure furnishing spermatozoids. In man the testicles are two in number, ovoid, and are developed from the genital gland, which in the fetus is situated below the lower pole of the kidney. Near the end of intrauterine life they normally descend, guided and drawn by the gubernaculum testis, through the inguinal canal to the scrotum, where they are suspended by the spermatic cords, the left hanging somewhat the lower. In their descent they derive a series of investitures from the several layers of the abdominal wall. Each testicle consists of a number of secreting tubules, which produce spermatozoa, the secretion being gathered through the corpus Highmori and discharged through the vas deferens.
