Summary Minor changes in procedure of preparing and mixing egg yolk media were found to have a marked effect on the settling of egg yolk and semen plasma solids. The visible settling of egg yolk and semen plasma solids during the storage or shipping of a diluted specimen of bull semen apparently has no influence on the duration of motility or survival of the spermatozoa. The sedimentation rate of the spermatozoa in most of the common semen-diluting media is very rapid under storage conditions. Apparently, at storage temperatures, the minute spermatozoa are behaving as inert particles, since the sedimentation rates of live and of dead cells were almost identical. In view of the rapid sedimentation rate of spermatozoa during storage, a diluted semen specimen should be thoroughly mixed prior to evaluation by the usual techniques or to utilization for artificial insemination. The evidence presented indicates that the rapid sedimentation of the spermatozoa during storage does not affect spermatozoan survival. |
