“…These changes were also associated with improvements in sperm parameters. Similar to our study, they also declared that RI is a useful parameter for detecting changes in testicular microhemodynamics after varicocelectomy ( 24 ). A key point of our study was that RI decreased more in patients with improved semen indexes compared with other patients.…”

Background: Varicocele is one of the leading causes of infertility in men. Resistance index (RI) in testis is a parameter indicating parenchymal perfusion and microvascular functions. Increased RI in the testis of patients with varicocele might be a sign of impairments in microvascularization and a significant decrease in testicular perfusion. In the present study, RI in capsular and intraparenchymal testicular arteries was evaluated in patients with varicocele who underwent varicocelectomy. Methods: This prospective cohort study was performed in 2019-2020 in Guilan, Iran. Sixty-six patients were included. Semen analysis was also done before surgeries. Patients with at least one disorder in semen analysis entered the study. RI in testicular arteries was measured by an experienced radiologist before surgeries. Six months after varicocelectomy, all patients underwent the same semen analysis and ultrasound imaging. Data were analyzed using SPSS software. The tests for analysis included McNemar Test and Wilcoxon and p<0.005 was considered as the significance level. Results: According to the results, 42 patients (63.6%) had positive changes in sperm analysis after surgeries. Sperm analysis showed a significant increase in number, concentration, morphology, and motility of sperm after surgeries (p<0.001). Further measurements of capsular and intratesticular RI in all patients also indicated a significant decrease (p<0.001). Conclusion: Increased RI might be associated with impaired microperfusion in testis followed by impairments in semen. Moreover, mean capsular and intratesticular RI in patients decreased after surgeries and this decrease was significantly more in patients who had improvement in their semen parameters.

“…In publications of Akand et al [18] and Ener et al, [19] varicose vein ligation increases PSV and EDV, as well as reduces RI in the capsular and intra-testicular arteries. This should be seen as an indicator of improved blood microcirculation in the testis.…”

We aimed at verifying the usefulness of spectral Doppler ultrasonography in determining development of the testis after torsion in boys.The study involved 28 patients and 30 control cases divided into 3 developmental groups: pre-pubertal, early pubertal, and pubertal. It presented surgical management in testicular torsion (TT), volume, and echogenicity of testes, as well as peak-systolic velocity (PSV), end-diastolic velocity (EDV), and vascular resistance index (RI) in the capsular and intra-testicular arteries, regarding developmental groups, detorsed testes, uninvolved ones, and testes in the control group.Orchiectomy was performed in 13 boys with complete TT, in 11 lasting for over 24 hours, and in 2 lasting for 9 and 10 hours, respectively. Orchiectomy mainly involved patients aged up to 6 years, who at the time of the follow-up ultrasound belonged to the pre-pubertal group.There is no clear correlation between the type of testicular torsion, its duration, and the echogenicity of the testis. Testicular torsion has a negative effect on the volume of detorsed testis with compensatory hypertrophy of the uninvolved testis. The study represents a new approach to the issue of long-term gonadal blood supply abnormalities after treatment of testicular torsion in childhood.

“…It is the method of choice for assessing the vascularity of different organs, including the testes 5 . Doppler is widely used in human medicine to evaluate testicular artery blood flow and pathological conditions, which are associated with blood flow alternation 6 . Recently, it has been used for assessment of testicular blood flow in domestic species as camels 7 , stallions 8 , bulls 9 , rams 10 , dogs 11 and goats 12 .…”

To fully understand the histological, morphometrical and heamodynamic variations of different supratesticular artery regions, 20 mature and healthy Assaf rams were examined through ultrasound and morphological studies. The testicular artery images of the spermatic cord as shown by B-mode analysis indicated a tortuous pattern along its course toward the testis, although it tends to be less tortuous close to the inguinal ring. Doppler velocimetric values showed a progressive decline in flow velocity, in addition to pulsatility and vessel resistivity when entering the testis, where there were significant differences in the Doppler indices and velocities among the different regions. The peak systolic velocity, pulsatility index and resistive index were higher in the proximal supratesticular artery region, followed by middle and distal ones, while the end diastolic velocity was higher in the distal supratesticular region. The total arterial blood flow and total arterial blood flow rate reported a progressive and significant increase along the testicular cord until entering the testis. Histological examination revealed presence of vasa vasorum in the tunica adventitia, with their diameter is higher in the proximal supratesticular zone than middle and distal ones. Morphometrically, the thickness of the supratesticular artery wall showed a significant decline downward toward the testis; meanwhile, the outer arterial diameter and inner luminal diameter displayed a significant increase distally. The expression of alpha smooth muscle actin and vimentin was higher in the tunica media of the proximal supratesticular artery zone than in middle and distal ones.
