The data for all statistical analyses were stratified for Tanner stage for genital development (TSG) and pubic hair (TSP). Non-parametric tests were used to assess the difference between right and left TV, and the prevalence of a ...However, in patients referred for ultrasound for the investigation of conditions such as subfertility, cryptorchidism or a previous history of testicular cancer, which already increases the risk of testicular cancer, the presence of TM further increased the risk of testicular cancer with an estimated risk ratio of 8.5. 28 In another series of testicular …Testicular atrophy is a medical condition in which one or both testicles (or "testes") diminish in size and may be accompanied by reduced testicular function.

These vessels join together, pass through the inguinal canal, and form single testicular veins, which drain into the vena cava on the right and the left renal vein on the left side. High-frequency ultrasonography (US) with a linear-array transducer is the modality of choice for the initial evaluation of patients with acute scrotal pain after trauma. Testicular trauma is the third most common cause of acute scrotal pain. US is useful in the triage of patients for medical or surgical management because it reliably depicts tunica …Testis intermittently retracts out of the scrotum due to an active cremasteric reflex and appears at the external inguinal ring. It can be observed in up to 80 % of patients aged 6 months to 11 years. Absence of the testis occurs in 3–5 % of surgical explorations for cryptorchidism.remaining five cases the affected testis appeared normal.
