“…Therefore, in the last years there were efforts for the detection in the pathologic changes of UDTs using noninvasive imaging modalities. Some previous studies, using Doppler ultrasonography (US) or Superb Microvascular Imaging demonstrated decreased perfusion in UDTs which was compatible with known histologic findings [8,9]. In addition, US elastography is a simple noninvasive method for measuring tissue elasticity [10].…”

“…Additionally, abnormal anatomical locations for UDTs may increase the risk for malignant transformations that could develop into testicular cancer [7]. Decreased vascularity in UDTs has also been demonstrated by histology [8]. However, there are limited tools to evaluate these histopathologic changes during neonatal and early childhood growth in boys.…”

Testicular volume and elasticity changes in young children with undescended testes

Aims: To evaluate the differences and changes of testicular volume and elasticity in normal (NL) testes and undescended testes (UDTs) of children using shear wave elastography (SWE).Materials and methods: Testicular ultrasound images from children younger than 60 months old were retrospectively reviewed. Testicular volumes and elasticities were compared between the UDT group and NL group. In patients with unilateral UDT (uUDT), we also compared the values between uUDT and contralateral grossly normal (CGN) testis groups.Results: There were 25 UDTs including 4 bilateral in the UDT groupand 54 normal testes in the NL group. While testicular volume was significantly smaller in UDT (vs. NL) and uUDT (vs. CGN) groups, the elasticity was not different. Testicular volume was positively correlated with age in both NL (r=0.474) and CGN (r=0.729) groups (p<0.001), while there was no correlation in the UDT group. Testicular stiffness showed negative correlation with age in the NL group (r=-0.390, p=0.004) and positive correlation in the UDT group (r=0.426, p=0.034).Conclusions: Instead of increasing volume and decreasing stiffness of normal testes during development of the early 60 months, UDTsexhibited smaller volume and increasing stiffness. The CGN testes of uUDT patients showed increasing volume without stiffness change.

“…In 1997 Atilla [1] reported that the arterial impedance of undescended testes in adults may have predictive value and provide more accurate information about histology than the testicular volume. The latter is inversely correlated with the pulsatility index (PI) of the transmediastinal artery, which has higher resistances in azoospermic than in oligoasthenospermic and normospermic men [2].…”

“…This technique has also been employed in the diagnosis of testicular pathologies and to assess the male fertility. CF and PW Doppler are routinely applied to evaluate the andrology status (Middleton and Melson 1989;Dubinsky et al 1998;Schurich et al 2009) because they are among the simplest and most accurate methods for measuring blood flow, as they combine information concerning anatomy and dynamicflow parameters (Atilla et al 1997). …”

Annual variations in resistive index (RI) of testicular artery, volume measurements and testosterone levels in bucks

The gonads of animals with sexual seasonality should change their metabolic requests throughout the year. In this study, we registered the variations of testicular volumes and serum testosterone levels in three Sarda bucks (Capra Hircus) and characterized the blood flow in the testicular artery by Doppler Ultrasonography, in order to shed light onto the type of relation between these parameters. After a 12-month study we observed that testicular volumes and testosterone levels show a typical seasonal variation with a maximum volume of testicular parenchyma recorded in September (116.06±25.22 ml) while testosterone reached its peak in December (620.43±192.87 ng/ dl). Blood supply and resistivity seem to follow the changes in the parenchyma according to the functional activity, and the lowest resistivity values were observed in September (0.73± 0.02). An inverse U-shape best describes the relationship between testicular volume and testosterone levels (p<0.05). This is the first report showing the changes in the blood supply to the testicular parenchyma of the buck throughout the year.
