| 摘 要： | 通过对海狸鼠生殖器官的位置、形态、解剖结构特点的系统详细地观察及大小重量的测定,结果表明：海狸鼠生殖器官的构造与其它哺乳动物基本相似,雄性海狸鼠的精囊腺、前列腺、尿道球腺３种腺体均成对存在,但其中的精囊腺特别发达,腺体的自然长度为７０２ｃｍ±０．４７ｃｍ（ｎ＝１４）,重为５３３ｇ±０７９ｇ（ｎ＝８）;值得提出的是雌性海狸鼠的子宫为长筒状双子宫颈的双子宫类型,即两子宫各自独立地开口于阴道,没有尿生殖道。公母海狸鼠肛门腺均发达。

| Abstract: | The result showed that the structure of reproductive organ in Myocastor coypus was similar to that in other mammals.The vesicular gland,the prostate gland,and the bilbourethera gland of the males all existed in pairs.The vesicular gland was well developed,with a length of 7.02 cm±0.47 cm (n=14),and a weight of 5.33 g±0.79 g(n=8).It should be noted that uteri in the nutria were classified as the type of double uterus with the two uterine horns opening separately into the vagina. |
