Vasculature phenotype of testis and seminal vesicles in Cul4b^L337M mice. The overall (A) and penises (B) appearance of Cul4b^L337M and wild-type mice. C Vasculature of testis in wild-type and Cul4b^L337M mice (2 and 5 months of age). The black arrow points to the testicular artery in wild-type mice. D Appearance of seminal vesicle in wild-type and Cul4b^L337M mice (2 and 5 months of age). The seminal vesicles of wild-type mice are deeply invaginated; however, mutant mice lack this characteristic
