Testicular microlithiasis on scrotal ultrasound in 4850 young men from the general population: associations with semen quality

Testicular microlithiasis (TM) is sometimes found on scrotal ultrasound. The prevalence seems higher in populations of men with testicular dysfunction, and TM may be a risk factor for testicular germ cell neoplasia in situ in men with additional risk factors. The association between TM and testicular function is controversial, especially in incidentally found TM.
