Abstract

The general form of the sperm head has been studied by ultra-violet and phase-contrast microscopy in ten species of mammal; the nature of the acrosome and the perforatorium are discussed. The acrosome varies greatly in size and shape between species. It is a relatively unstable structure and degenerative changes leading to its complete removal from the sperm head after the death of the cell occur spontaneously and can be induced experimentally. The perforatorium was demonstrated in five species of rodent and its universal existence in mammalian spermatozoa is postulated.
