title: [Periodicity of spermatozoa movement].
abstract: A method of Laser Doppler Spectrometry is used to study the periodicity of bulls' spermatozoa motion. The period of their motion is divisible by 24 turns of spermatozoa heads. The interrelation of the observed periodicity with the ultrastructure of bulls' gametes tails is suggested.
