Abdominal testes of adult, naturally unilaterally cryptorchid boars were subjected to continuous artificial cooling for 5, 15, 25, or 45 days. This treatment initiated development of the spermatogenic epithelium. After a cooling period of 45 days there was complete differentiation in many seminiferous tubules. The results indicate that the spermatogenic arrest in abdominally located testes is not due to an inborn defect in the testis, but is caused by the maintenance of the testis at the abdominal temperature.
对成年自然单侧隐睾公猪的腹腔内睾丸进行持续人工降温处理，持续时间分别为5天、15天、25天或45天。这种处理引发了生精上皮的发育。在45天的降温期后，许多生精小管出现了完全分化。结果表明，腹腔内睾丸的生精停滞并非由于睾丸先天性缺陷，而是由于睾丸维持在腹腔温度所致。
