Notulae seminologicae. 2. The 'short tail' and 'stump' defect in human spermatozoa.
In this note several cases of stunted tails involving the total sperm population in sterile humans are described. Half of the cases are classified as 'short tailed' spermatozoa, the other half as 'stump defect' previously described in bulls. Both defects are referred in details at electron microscopical level.
