%X Cryptorchidism is a congenital abnormality resulting in increased rates of infertility and testicular cancer. We used cryptorchidism model mice that presented with the translocation of the left testis from the scrotum to the abdominal cavity. Mice underwent the surgical procedure of the left testis at day 0 and were sacrificed at days 3, 5, 7, 14, 21, and 28 post-operatively. The weight of the left cryptorchid testis decreased significantly at days 21 and 28. The morphological changes were observed after 5 days and showed detached spermatogenic cells and abnormal formation of acrosome at day 5, multinucleated giant cells at day 7, and atrophy of seminiferous tubules at days 21 and 28. The high abdominal temperature disrupted the normal expression of cell adhesion molecule-1, Nectin-2, and Nectin-3 which are essential for spermatogenesis. In addition, the pattern and alignment of acetylated tubulin in cryptorchid testes were also changed at days 5, 7, 14, 21, and 28. Ultrastructure of cryptorchid testes revealed giant cells that had been formed by spermatogonia, spermatocytes, and round and elongating spermatids. The study's findings reveal that cryptorchidism's duration is linked to abnormal changes in the testis, impacting protein marker expression in spermatogenic and Sertoli cells. These changes stem from the induction of high abdominal temperature.
