Cooling experiments of abdominal testes in adult, naturally cryptorchid pigs indicate that spermatogenic arrest in abdominal testes is not due to an inborn defect, but is caused solely by maintenance of the testis at abdominal temperature. It is postulated that failure of spermatogenic cells to differentiate after orchiopexy results from surgical trauma. Evaluation of the orchiopexy procedure revealed that simple manipulation of a normally descended testis may give rise to damage to the spermatogenic epithelium. Furthermore, it appeared that, in normally descended testes of naturally unilaterally cryptorchid pigs subjected to orchiopexy, the spermatogenic epithelium was poorly developed as compared with that of scrotal testes of unilaterally cryptorchid pigs that had not undergone a surgical procedure.
对成年自然隐睾猪的腹腔睾丸进行的降温实验表明，腹腔睾丸生精停滞并非由于先天性缺陷，而是完全由睾丸维持在腹腔温度所致。据推测，睾丸固定术后生精细胞分化失败是手术创伤造成的。对睾丸固定术的评估显示，对正常下降的睾丸进行简单操作可能会导致生精上皮受损。此外，在接受睾丸固定术的自然单侧隐睾猪的正常下降睾丸中，与生精上皮未接受手术的单侧隐睾猪的阴囊睾丸相比，其生精上皮发育不良。
