本文对NIG-III系大鼠11; Y易位的杂合子和纯合子以及X/X/dot-Y和X/dot-Y/dot-Y性染色体的睾丸进行了组织学检查。11; Y易位杂合子和可育男性的组织学特征与正常男性基本相似，但不育杂合子、纯合子和其它X/X/dot-Y和X/dot-Y/dot-Y男性的曲细精管普遍小于正常男性，生殖细胞变性透明。在这些睾丸中未观察到任何精子发生。不育雄性生殖细胞的退化方式因易位类型的不同而不同。
The present paper deals with the histological examination of the testis of the NIG-III strain rats with the 11; Y translocation in the heterozygous and the homozygous conditions, and those with the X/X/dot-Y and the X/dot-Y/dot-Y sex chromosomes. The histological feature of the 11; Y translocation heterozygous and fertile males is almost similar to that of the normal male, but in the sterile heterozygous males, homozygous males and the other X/X/dot-Y and the X/dot-Y/dot-Y males, the seminiferous tubules is generally smaller than that of the normal one, and the germ cells are always degenerated and hyalinized. Any spermatogenesis has not been observed in these testis. The mode of the degeneration of the germ cells in the sterile males differs by difference of the type in the translocation.
