Summary. Electron microscope examination of rat testes 1, 3 and 7 days after ligation of the ductuli efferentes showed that the horseradish peroxidase tracer penetrated into the basal compartment of the seminiferous tubules, but the marker did not progress beyond the junctional complexes between Sertoli cells. These findings indicate that in spite of the severe morphological changes brought about by ligation, the tight junctions between the Sertoli cells maintain their capacity to act as the testis barrier.

Reproduction is committed to supporting researchers in demonstrating the impact of their articles published in the journal.

The two types of article metrics we measure are (i) more traditional full-text views and pdf downloads, and (ii) Altmetric data, which shows the wider impact of articles in a range of non-traditional sources, such as social media.
