Light and electron microscopic studies on testicular development in swamp buffalo bulls (Bubalus bubalis)

The epithelium of seminiferous tubules of immature Malaysian swamp buffalo bulls from 6 months to 32 months of age was studied by light and transmission electron microscopy with a view to determining the structural features in the seminiferous tubules that could possibly contribute towards an except...
