Objective: The aim of the present study was to investigate the diagnostic value of strain elastography (SE) of testicular tissues in infertile population. We also evaluated the correlation between SE results with semen parameters and hormone profiles of the patients. Material and methods:A total of 61 patients and 122 testes were evaluated. Patients who were evaluated in an andrology outpatient clinic with the diagnosis of infertility and referred to radiology department for investigation of reproductive organs between June 2015 and January 2016 were included. Patients were divided into two groups according to semen analyses results as normal (Group 1) and abnormal (Group 2). Hormone profiles, semen analyses, B-mode, coloured Doppler ultrasonography and sonoelastography examinations were performed for each patient. Measurements of testicular volumes, resistive indices (RI) in intraparenchymal arteries, strain, strain ratio (SR) and presence of varicocele were recorded.Results: Mean age of participants was 33.7±6.3 years. Mean testicular volumes (Group 1, 19.41±4.8 mL, and Group 2, 17.64±3.62 mL) were significantly different between groups (p= 0.023). Mean SRs were also different between Groups 1 and 2 (0.12±0.08 vs. 0.22±0.18, p<0.001). Testicular volumes were directly proportional with SRs in Group 1. Strain values had inverse relationship with sperm concentration and total motile sperm counts in Group 2 (p= 0.01). SRs were found to be positively correlated with RI and sperm morphology in Group 2 (p<0.05). Although FSH values showed significant difference among groups, any correlation between FSH and elastographic parameters could not be displayed. Conclusion:Strain elastography results were found to be significantly different in patients with abnormal sperm counts. This technique may provide promising results, however, further large scale studies may help to clarify the value of this imaging modality in the assessment of male infertility.

“…Varicocele can be easily shown with standard ultrasonographic examinations and can be confirmed by color Doppler ultrasound (CDU), which provides a noninvasive assessment of testicular arterial and venous structures [1]. The problem with the varicocele is not in the diagnosis, which is quite easy, but with further management.…”

“…Because varicocele is a vascular DOI: 10.1159/000500027 event, there have been many studies focused on vascular structures to provide information about pathophysiology and effects of varicocele on testis parenchyma [1]. As a noninvasive method color/spectral Doppler ultrasound analysis was tried to provide valuable information to assess the hemodynamic changes and testicular microcirculation status in cases of clinical varicocele.…”

Aim: The aim of the study was an assessment of the effects of varicocele on testis parenchyma and microcirculation with the use of the dynamic tissue perfusion measurements. Methods: Color Doppler sonographic dynamic testis parenchyma perfusion measurements were performed with PixelFlux software in 30 children with left testis varicocele. The right testes without varicocele comprised the control group. Results: Testicular parenchymal perfusion in testes with varicocele was reduced when compared to the control testes. The differences were found in all measured perfusion parameters. Statistical significance was found in the case of mean velocity and resistance index parameters. According to the grade of varicocele, the perfusion was the most reduced in patients with grade III of varicocele. Conclusion: Testicular parenchymal perfusion decreases in patients with varicocele, mostly in higher grades of varicocele. In case of validation, the method can be used in determining the damage of the testis with varicocele and the need for surgery.

“…Ultrasonography (US) is currently the most established and widely used modality for the study of varicoceles, with 97% sensitivity and 94% specificity in the diagnosis of clinical varicocele and 83%-95% sensitivity in the diagnosis of subclinical varicocele[5,12,13,33,36,37]. The classic US features of a varicocele is that of “multiple, anechoic, serpiginous, tubular structures” near the superior and lateral aspects of the testis.…”

“…However, in subsequent studies, CDUS proved to be sensitive in assessing alterations in intratesticular circulation in testes with clinical varicocele[37,49,54-56]. A significant decrease in testicular arterial blood flow and an increase in RI and PSV in testes with clinical varicocele were reported[37,49,54-56].…”

Varicocele is characterized by an abnormal dilatation and retrograde blood flow in the spermatic veins. Varicocele is the leading correctable cause of male infertility. Although it is highly prevalent in infertile men, it is also observed in individuals with normal fertility. Determining which men are negatively affected by varicocele would enable clinicians to better select those men who will benefit from treatment. To assess the functional status of the testes in men with varicocele, color Doppler sonographic parameters were evaluated. Testicular arterial blood flow was significantly reduced in men with varicocele, reflecting an impairment of spermatogenesis. An improvement in the testicular blood supply was found after varicocelectomy on spectral Doppler analysis. Testicular contrast harmonic imaging and elastography might improve our knowledge about the influence of varicocele on intratesticular microcirculation and tissue stiffness, respectively, providing possible information on the early damage of testicular structure by varicocele. Magnetic resonance imaging (MRI), with measurement of apparent diffusion coefficient has been used to assess the degree of testicular dysfunction and to evaluate the effectiveness of varicocele repair. Large prospective studies are needed to validate the possible role of functional sonography and MRI in the assessment of early defects of spermatogenesis in testes with varicocele.
