context_page_description: Testicular microlithiasis is an unusual condition diagnosed on testicular ultrasound. It is found in between 1.5 to 5% of normal males, and may be found in up to 20% of individuals with subfertility. It is an asymptomatic, non-progressive disease.
  Testicular microlithiasis is not associated with risk of testicular cancer in asymptomatic individuals with no risk factors for testicular germ cell tumor. However, a large meta-analysis has shown that in individuals with associated risk factors for testicular germ cell tumor, the increase in risk of concurrent diagnosis of testicular germ cell tumor, or testicular carcinoma-in-situ upon biopsy is approximately eight to ten-fold.
  There is extensive controversy over whether testicular microlithiasis in individuals with testicular germ cell tumor, or risk factors for such, should undergo testicular biopsy to exclude the presence of testicular carcinoma-in-situ, also known as intratubular germ cell neoplasia of unclassified type. Additionally, whether the presence of testicular microlithiasis should influence decision for adjuvant chemotherapy or surveillance in individuals with testicular germ cell tumor remains unclear.

A recent review in Nature Reviews Urology has comprehensively evaluated these topics.
