OBJECTIVES: To assess the risk of azoospermia development and the value of sperm retrieval in post-pubertal testicular torsion (TT).
MATERIALS AND METHODS: This prospective study included patients with post-pubertal TT. Surgical exploration was urgently performed with either orchiopexy or orchiedectomy and contralateral orchiopexy. With the intention of cryopreservation, all cases underwent conventional testicular sperm extraction. Patients were followed-up after 1, 3, and 6 months with semen analysis and hormonal assay (FSH, LH and testosterone). Sperm retrieval rate (SRR), azoospermia rate and changes in hormonal profile were evaluated.
RESULTS: The study included 62 patients with a median (IQR) age of 19 (18-20.7) years and duration of testicular torsion of 32.5 (18.3-48) hours. Testicular salvage was successful in 20 (32.3%) while orchiedectomy was performed on 42 patients. The duration of torsion [OR, 95% CI = 0.75 (0.61-0.93), P = .008] was the independent predictor of testicular salvage. Successful SR was achieved in 58 patients (93.5%); (40 from the affected testis and 18 from the contralateral side). After 6 months, 21 patients (33.8%) developed azoospermia [19 (45.2%) in orchidectomy group and 2 (10%) in orchiopexy group, P = .006]. Abnormal contralateral testis was the independent predictor of azoospermia [OR, 95% CI = 92(8.4-101.5), P < .001]. Azoospermia patients showed a statistically significant increase in FSH and LH and decrease in testosterone level as compared to the non-azoospermia group (P < .001).
CONCLUSION: Azoospermia is not rare in post-pubertal TT patients; therefore, SR at time of intervention seems to be a good option for them to preserve their fertility potentials.
