Testicular doppler resistive index parameter as predictor test for male infertility

الملخص EN

Aim : to assess the role of color Doppler ultrasonography (CDUS) resistive index (RI) parameter as a predictor test for spermatogenesis and infertility. Patients and Methods : This is a prospective study done on 80 patients,40 individuals with normal sperm counts, the other 40 individuals with abnormal pathologic sperm counts, those individuals examined by CDUS, RI were calculated on both sides using two parenchymal arteries at upper &lower pole of testes the data were analyzed statistically by SPSS software using t-test at level of significance P < 0.05. Results : Individuals with normal sperm counts had mean (SD) RI = 0.566(0.0342), those with abnormal pathological sperm counts had mean (SD) RI = 0.673(0.093).

Statistical analysis show significant difference between the two groups P = 0.002 Conclusion : These results suggest that CDUS RI parameter can be used as a simple, safe, rapid and noninvasive predictor test for spermatogenesis and infertility.
