Summary
After cultivation of dissociated rat testicular tissues, H-Y antigen is detectable in the medium; this is not the case if nongonadal male tissues are incubated. Release of H-Y antigen by testis cells is inhibited by the addition of cycloheximide. All tissues still type H-Y positive after culture. It is assumed that the testis actively secretes H-Y antigen. This assumption is supported by the finding that the amount of H-Y antigen in the epididymal fluid increases with the age of the animals.
