Abstract To investigate the application value of virtual touch quantification (VTQ) technique for evaluating infertility of man with varicocele. Methods: 120 infertile men with varicocele were selected in study group from November 2016 to November 2019, and the normal men with normal ultrasound and semen who wanted physical examination were selected in control group during the same time. The sperm concentration and motility, testicular volume, and transverse shear wave velocity (SWV) of men in the two groups were measured. The correlation of SWV value with semen quality and testicular volume was analyzed. Results: The sperm concentration and motility of men in the study group were significant lower than those of men in the control group. The volume of left testis of men in the study group was significant smaller than that of their right testis and the men in the control group (P＜0.05). The sperm concentratio of men with worse varicocele was significant less, their motility of sperm was significant lower, and their left testicular volume was significant smaller (P＜0.05). The SWV value of left testis of the men in the study group was significant lower than that of men in the control group (P＜0.05). SWV value was positively correlated with the sperm concentration, motility and testicular volume (P＜0.05). Conclusion: The testicular SWV measured by VTQ may be an indirect index for evaluating the volume and tissue hardness of testicular, and semen quality of infertility men with varicocele.
