The aim of the study was to measure the testicular artery blood flow parameters in infertile patients with varicocele as compared with normal fertile men. The study was carried out on 60 infertile patients with varicocele and 20 fertile patients with varicocele, also 20 fertile men with no varicocele were included as control group. All patients were subjected to history taking, general and local genital examination. Conventional semen analyses were performed twice in patient group. Hormonal profile was done to the infertile patient group. Scrotal color Doppler ultrasound measurements of vein diameter, testicular volume and testicular artery blood flow parameters were done for both patients and control groups. The results showed that evaluation of testicular artery blood flow shows that it is most high in infertile patients with varicocele regardless of the degree of vein diameter, becomes less higher in fertile patients with varicocele and is of least value in fertile patients with no varicocele.
