抄録

The volume of spermatozoa was measured in some mammals. The distribution range of O spermatozoa extended from 10 to 50μ3, from 10 to 35μ3, from 1.25 to 6.75μ3, and from 5 to 45μ3 in mice, rats, guinea pigs, and swine, respectively. It was assumed that the value might be too small for guinea pigs. Monomorphic distribution was noted in O of swine and in all the cases of mouse, rat, and guinea pig. A peak of monomorphic curve was seen at about 20, 20, 2.5, and 14μ3 in mouse, rat, guinea pig, and swine, respectively. Dimorphic distribution was observed only in the W and S curve for swine. As compared with the O and W curve, the S curve shifted to the left in mouse and guinea pig. The S curve of swine was clearly dimorphic. Its two peaks were of the same height, except that the left peak was lower than right in the W curve. It is unknown whether or not the right and left peaks represent X-and Y-spermatozoa, respectively.
