Human spermatozoa: unidirectional rotation of the tail as indicated by head-to-head agglutinates

Arch Androl. 1979 Mar;2(2):157-61. doi: 10.3109/01485017908987307.


Rotating head-to-head agglutinates of human spermatozoa were always observed to turn counter-clockwise. The phenomenon seems to suggest a unidirectional rotatory component in the tail movement that may be related to the substructure of the axoneme.
