尿道是性传播病原体进入的主要场所。然而，关于泌尿生殖系统形态学的文献很少，主要是尿道和性附腺导管。蒙古沙鼠是一种食虫、食草、单配偶的啮齿类动物，具有夜行习性;自20世纪60年代以来，它一直被成功地用作实验动物。本研究对长爪沙鼠尿道的结构和超微结构及其与副性腺导管的关系进行了系统的观察和研究，为进一步了解长爪沙鼠的生殖生物学和相关的实验研究提供资料。利用光学和扫描电子显微镜的常规技术。附性腺的尿道和导管与白化病大鼠和小鼠相似。但内尿道各附属性腺的引流方式存在差异。精囊的导管，输精管，将其内容物独立地排入开口于尿道的壶腹管。前列腺、尿道腺和尿道球腺的导管将其内容物独立地排入尿道。
The urethra is the main place of entry for sexually transmitted pathogens. However, there is little literature on the morphology of the urogenital system, principally the urethra and ducts of the sex accessory glands. The Mongolian gerbil is an insectivorous, herbivorous and monogamous rodent with nocturnal habits; it has been used successfully as a laboratory animal since the 1960s. Therefore, the objective of the present paper was to describe the structure and ultrastructure of the urethra and its relations to the ducts of the accessory sex glands of the Mongolian gerbil (Meriones unguiculatus), contributing to the understanding of the reproductive biology of the rodent and aiming to provide data for future experimental studies. Conventional techniques of light and scanning electron microscopy were utilized. The urethra and ducts of the accessory sex glands are similar to those of the albino rat and the mouse. However, there is variation in drainage type among accessory sex glands for the inner urethra. The ducts of the seminal vesicle, the ductus deferens, drain their contents independently into the ampullary duct that opens in the urethra. The ducts of the prostate, coagulating and bulbourethral glands drain their contents independently into the urethra.
