Testes and seminal vesicles of adult wild-type (WT) and FshrKO mice (left panels), and testicular histology of the same genotypes (right panels). No difference was observed in seminal vesicle sizes between the two genotypes, but the size of the FshrKO testes is about half that of the WT. Furthermore, while full spermatogenesis is visible in the histology of both testes, the tubular diameter is clearly narrower in the knockout testis.
