The Functional Anatomy of the Spermatozoon is the 23rd volume of the series Wenner-Gren Center International Symposium Series, documenting the proceedings of the Second International Symposium on Comparative Spermatology, held in August 1973. This volume mainly focuses on the understanding of the early events at fertilization and the preliminaries of this biological process. This text specifically tackles the sperm at fertilization of lower animals and mammals, sperm motility and diversity, and spermatogenesis. This book concludes with discussions on capacitation and maturation of mammalian spermatozoa. This compendium will be valuable to morphologists, physiologists, immunologists, and biochemists, as well as to academicians interested in the study of functional anatomy of the spermatozoon.
