The aim of this study was to investigate the impacts of gradual low-flow reperfusion postconditioning (GLFRP) on testicular ischemia–reperfusion injury (IRI). A rabbit testicular ischemia model was established, and rabbits were divided into mild ischemia groups (the IRm, IPm1, IPm2, IPm3, and IPm4 groups) and moderate ischemia groups (the IRM, IPM1, IPM2, IPM3, and IPM4 groups). The IRm and IRM groups underwent direct reperfusion. The IPm1 and IPM1 groups, and the IPm3 and IPM3 groups, received 45 and 30 s maintained low-flow reperfusion. The IPm2 and IPM2 groups, and the IPm4 and IPM4 groups, were subjected to 45 and 30 s gradual low-flow reperfusion. The SOD and Johnsen’s score of testicular tissue on the surgical side 3 days after reperfusion were determined. The SOD activities in the IP3 and IP4 groups were higher than those in the IR, IP1, and IP2 groups (P

This work aims to investigate high-frequency ultrasound findings in epididymal malformations and their clinical significance. Eighty-five of 9,849 patients who had been examined using high-frequency ultrasound for infertility, varicocele, scrotal swelling, and so on had epididymal malformations. A retrospective analysis was conducted on the ultrasound findings of epididymal malformations in these 85 patients. There were a total of 117 malformed epididymides in 85 patients with epididymal malformations. The detection rate of epididymal malformations using high-frequency ultrasound was 0.86 % (85/9,849). High-frequency ultrasound can be used to diagnose epididymal malformation and seminiferous duct blockage.
