Abstract

To describe the macroscopic anatomy of the genital organs of the male pampas deer (Ozotoceros bezoarticus), organs from ten animals found dead in a captive breeding station were dissected. The unpigmented scrotum was located in the inguinal region near the body, and was covered by the thighs. In the investments of the testicles the dartos tunic was greatly developed. The cremaster muscle was located dorsocaudal to the testicle, and was divided caudally into three bundles of fibers. The right testicle was significantly heavier than the left, and there was a positive relationship between body weight and the weight of both testicles. The tail of the epididymis, ventrally located, had a caudal portion attached to the caudal extremity of the testicles by the proper ligament of the testicles, and a portion elongated free caudally located. The deferent duct was located caudomedially to the corresponding testicle. The accessory genital glands were the ampullary glands, vesicular glands, and a small pars disseminata of the prostate. The penis was fibroelastic, without sigmoid flexure, with a thick albuginea. The retractor penis muscle was very long, and ended in the distal part of the penis near the rudimentary glans. The general disposition of the male genital organs of the pampas deer were similar to that of other ruminants, with some differences, such as size and location of the testicles, the absence of the sigmoid flexure of the penis, and fewer accessory genital glands.
