In the hopping mouse, Notomys alexis, there are very small testes and relatively low numbers of spermatozoa in the extragonadal ducts. Large ventral prostates are present, but the seminal vesicles, coagulating glands, ampullaries, and dorsal prostates are all extremely small, although their histological structure and secretory activity is similar to that of the laboratory murids. Bulbourethrals are typical, but the preputials are very small and composed of sebaceous secretory units and an associated hair follicle. The possible functional significance of these findings is briefly discussed.
在长耳跳鼠（Notomys alexis）中，其睾丸非常小，性腺外管道中的精子数量相对较少。存在较大的腹侧前列腺，但精囊、凝固腺、壶腹腺和背侧前列腺都极小，尽管它们的组织结构和分泌活动与实验室小鼠相似。尿道球腺是典型的，但包皮非常小，由皮脂腺分泌单位和相关的毛囊组成。文中简要讨论了这些发现可能具有的功能意义。
