The effect of freezing of boar semen on the morphology of spermatozoa



The effect of freezing of boar semen on the morphology of spermatozoa



Sel' skokhozyaistvennaya Biologiya 11(3): 426-429, 477



Microphotographs were made of Feulgen-stained boar spermatozoa which had been held at 30 deg or 0 deg C, or frozen to -196 deg. Nucleus and head areas were then measured by planimetry. Measurements are given in 3 tables and in histograms. The results indicated that contraction of the acrosome and nucleus occurred during freezing, although overall head size increased due to swelling of protoplasm.
