Two types of testicular tumor were evident in cyprinid fishes collected from Lake Ontario. Both types of tumors appeared to be of Sertoli cell origin. One contained predominantly Sertoli cells with little or no lipid content and germinal cells in only small numbers. The second contained large numbers of spermatogonia together with Sertoli cells that contained large amounts of lipid and smooth endoplasmic reticulum. Small, apparently inactive Leydig cells were present in both types of tumors and also in testes of fish not bearing gonadal tumors.
在从安大略湖采集的鲤科鱼类中发现了两种类型的睾丸肿瘤。这两种肿瘤似乎都起源于支持细胞。一种主要含有支持细胞，脂质含量很少或没有，生殖细胞数量也很少。另一种含有大量精原细胞以及含有大量脂质和滑面内质网的支持细胞。两种类型的肿瘤以及未患性腺肿瘤的鱼类睾丸中都存在小的、明显无活性的间质细胞。
