Notes:
An elongate crystalloid inclusion has been noted in the cytoplasmic droplet of cauda epididymal bovine spermatozoa. The crystalloid appears to be composed of an aggregate of parallel 10 nm diameter filamentous elements that are associated laterally with one another. It has a regular cross-banding pattern that repeats at 13-15-nm intervals. A purified fraction of detached droplets was prepared by centrifugation of sperm suspensions onto Percoll gradients. The detached droplets also exhibited the crystalline inclusion. The origin and possible functions of this structure are discussed.
