This document outlines the anatomy of a boar's reproductive system. It describes the location and function of the testis, seminal vesicles, cauda, epididymis, caput, ductus deferens, glans penis, bladder, Cowpers gland, sigmoid flexure, retractor penis muscle, scrotum, spermatic cord, external cremaster muscle, tunica layers, corpus epididymis, testicular artery, rete testis, seminiferous tubules, and Leydig cells. Diagrams are included to illustrate the structures and their relationships.
