A scanning electron microscopic study of the rete testis of the guinea pig.
Scanning electron microscopic (SEM) observations of the structure of the rete testis (RT) of guinea pigs preceded by and complemented with stereomicroscopy and light-microscopic studies showed that the RT of this species is predominantly cavitary. An axial and labyrinth-like morphological pattern was also observed in the RT complex, with partially interconnected chambers and epithelium-lined channels accompanying a connective axis observed in the middle portion of the cranial end of the testis. Characteristics of the chordaeretis and bullaeretis were also visualized in the guinea pig RT and the results are discussed in terms of the morphological patterns observed in the RT of other mammals and of man.
