The Mammalian Spermatozoon
Don W. Fawcett
As we approach the three hundredth anniversary of the discovery of the spermatozoon (1677) it seems timely to review what we know of the structure of this fascinating cell. Perhaps no better example could be found of the slow beginnings of biological science and of the rapid recent acceleration in the tempo of discovery resulting from advances in instrumentation.

1677 Discovery
Anton van Leeuwenhoek a Dutchman who developed the early compound microscope. In 1677 on examination of his own ejaculate and identified tiny “animalcules” he found wriggling inside.
Royal Society London 1677.
