The spotted paca is the second largest rodent in Brazil, where it is of great economic interest in impoverished regions in view of its prominence as a low-cost source of protein. Little is known about the morphology of the accessory genital glands of this species. Thus, we studied the position and morphology of the genitals in ten adult male spotted pacas. The animals were divided into two groups, five animals were used for fixing of samples in 10% aqueous formaldehyde for macroscopic studies and the other five animals were designated for microscopic analysis. These were arranged in pairs and had the vesicular, prostate, coagulating and bulbourethral glands identified, being structured as mucous glands, which lead into the pelvic urethra. It was concluded that the accessory genital glands found in the paca are the same as those found in most rodents, showing similar histological aspects.
斑点天竺鼠是巴西第二大啮齿动物，鉴于其作为低成本蛋白质来源的突出地位，在贫困地区具有重大经济意义。人们对该物种附属生殖腺的形态了解甚少。因此，我们研究了10只成年雄性斑点天竺鼠生殖器的位置和形态。这些动物被分为两组，5只用于在10%甲醛水溶液中固定样本以进行宏观研究，另外5只用于微观分析。这些腺体成对排列，可识别出泡状腺、前列腺、凝固腺和尿道球腺，它们结构上为黏液腺，通向盆腔尿道。得出的结论是，天竺鼠体内发现的附属生殖腺与大多数啮齿动物的相同，具有相似的组织学特征。
