Objective To evaluate the clinical efficacy of electrophysiological appropriate technology in patients with idiopathic asthenozoospermia accompanied by high sperm DNA fragmentation index (DFI > 15%). Methods A retrospective analysis was conducted on 92 patients with asthenozoospermia accompanied by elevated DFI who attended the Reproductive Medicine Center of the Sixth Affiliated Hospital of Sun Yat-sen University between March 2021 and February 2026 and completed one course of standardized electrophysiological appropriate technology treatment. Before and after treatment, all patients underwent visualized precise electrodiagnosis, routine semen analysis and DFI assessment, and pregnancy outcomes of their partners were followed up. Results After treatment, scrotal temperature decreased significantly compared with that before treatment (32.58 [32.00,34.12] ℃ vs 32.04 [31.07,33.48] ℃, P<0.01), whereas no statistically significant differences were observed at other sites (P>0.05). The percentage of progressive motility (PR) increased significantly after treatment (14.00% [8.00%,25.00%] vs 24.00% [12.00%,35.75%], P<0.01), while semen volume and sperm concentration showed no statistically significant differences before and after treatment (P>0.05). The DFI after treatment decreased significantly compared with that before treatment ([47.33 ± 11.05] % vs [37.22 ± 14.90] %, P<0.01). Efficacy evaluation showed that the response rate for improvement in asthenozoospermia was 80.43%. The response rate for DFI improvement was 66.30%, and the combined response rate (based on simultaneous evaluation of PR and DFI) was 63.04%. Conclusion Electrophysiological appropriate techniques can reduce local scrotal temperature in patients with idiopathic asthenozoospermia accompanied by elevated DFI, improve PR, and decrease DFI, suggesting that it may serve as an optional adjunctive intervention for this patient population.
