Abstract

Purpose: To determine whether testicular cryoablation caused histopathological orchiectomy, and to show its effects on serum total testosterone (t-testosterone) levels in rats.

Materials and Methods: A total of 12 Wistar albino male rats were used in this study. The animals were divided into two groups, as cryoablation (9 rats) and control (3 rats) groups. Bilateral cryoablation was performed in the cryoablation group. T-testosterone levels were measured in both groups before scrotal exploration. Bilateral or­chiectomy was performed in both groups 10 days after the cryoablation procedure. T-testosterone was measured immediately before orchiectomy. Mann-Whitney U test was used for intergroup comparisons.

Results: Baseline t-testosterone levels were 1.31 (0.78-2.45) ng/mL and 0.98 (0.91-2.05) ng/mL in the cryoab­lation and the control groups, respectively (P = .92). T-testosterone levels were 0.23 (0.07-1.12) ng/mL and 2.87 (0.63-3.06) ng/mL in the cryoablation and the control groups, respectively, in the blood samples obtained at the time of orchiectomy (P = .03). Histopathological examination of rat testes revealed varying degrees of paratestic­ular inflammation and necrosis in 13 of 18 testes in the cryoablation group. None of 6 testes showed necrosis in the control group.

Conclusion: Our study showed that histopathological orchiectomy could be obtained by cryoablation in rat testes.
