Abstract: In the course of an investigation of the response of spermatozoa in the epididymis of rabbits to the effects of artificial crytorchidism, it was noted that in the controls (that is, 12 normal epididymides on which no operative interference had been undertaken) a remarkable number of immotile decapitated spermatozoa was present in samples withdrawn from regions of the tubule proximal to the cauda epididymidis. Spermatozoa of this kind have been previously referred to as disintegrated spermatozoa´1,2 and presumably indicate a process of degeneration. In the present work the morphology of spermatozoa was examined in saline-diluted squash preparations under the phase-contrast microscope and in whole specimens. Quantitative estimates of particular characteristics were made from smears after staining with aqueous nigrosin eosin differential stain3 in order that an estimate of the proportion of dead (eosinophilic) spermatozoa also might be made. In view of this finding, spermatozoa from epididymides of some other species, namely the bull (6 specimens), the goat (2 specimens), the dog (4 specimens) and the cat (3 specimens) were also examined. |
