Reproductive System, Male

Epididymis

Narrative

Accessory sex organs in the male reproductive system, in addition to the prostate, include the seminal vesicles, preputial glands, ductus deferens, and penis. These tissues can exhibit direct and indirect (often hormonal) pleotrophic pathologic responses. A change in one reproductive tissue is often accompanied by changes in other reproductive tissues. The majority of the male reproductive tissues are paired, allowing identification of unilateral versus bilateral responses. Artifacts are rare.
