title: [Abnormalities in the acrosome structure of drake spermatozoa].
abstract: Changes in the acrosome structure of drake spermatozoon were studied electron--microscopically. There were changes in the position of the acrosomal spine in the nucleus, the presence of two spines. The acrosome cap was observed to bear shape changes; other structure and vacuoles were present in the cap. Pronounced changes on acrosomal cap and acrosomal spine were observed in spermatozoa having nuclei with considerable shape deformations.
