<unk>  on ultrasound<unk>  is an unusual condition diagnosed on<unk>  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.<unk>  is not associated with risk of<unk>  cancer in asymptomatic individuals with no risk factors for<unk>  germ cell tumor. However, a large meta-analysis has shown that in individuals with associated risk factors for<unk>  germ cell tumor, the increase in risk of concurrent diagnosis of<unk>  germ cell tumor, or<unk>  carcinoma-in-situ upon biopsy is approximately eight to ten-fold. There is extensive controversy over whether<unk>  in individuals with<unk>  germ cell tumor, or risk factors for such, should undergo<unk>  biopsy to exclude the presence of<unk>  carcinoma-in-situ, also known as intratubular germ cell neoplasia of unclassified type. Additionally, whether the presence of<unk>  should influence decision for adjuvant chemotherapy or surveillance in individuals with<unk>  germ cell tumor remains unclear. A recent review in Nature Reviews Urology has comprehensively evaluated these topics.
