This chapter examines the novel structural features of the spermatozoon, their composition
and assembly, and the mechanisms regulating their function. The spermatozoon is a highly …

Publisher Summary This chapter discusses membrane heterogeneity in the mammalian
spermatozoon. Mammalian spermatozoa, after leaving the testis, are subjected to a …

Although it is generally understood that the testes recruited kidney ducts for reproductive
function during the evolution of vertebrates, little is understood of the biological significance …

Chinese hamster spermatozoa gain their ability to move when they descend from the testis
to the distal part of the caput epididymis, but it is not until they enter the corpus epididymis …

The spermatogenesis and spermatozoa of mammals are of fundamental interest to a wide
variety of academic and scientific disciplines; zoologists keep up interest in comparative …

The ultrastructure of fertilization has been studied in rabbit eggs recovered 11 to 15 hours
after natural mating. Many sperm passing between the granulosa cells had undergone the …

By use of cytochemistry in conjunction with automatic image analysis it was shown that ram
spermatozoa carried a low level of negative charge on, or shortly after, entering the …

Sperm quality in the caput, corpus, and cauda regions of the epididymis of healthy and
sexually mature Landrace boars was studied. Epididymal sperm characteristics were …

This introductory chapter offers a basic overview of male reproduction, specifically the
anatomy and physiology of the male reproductive system. Comprehension of normal …

The ultrastructure of 12 steps of spermatid development and the process of spermiation are
described for the Japanese quail in order to clarify the classification proposed for …
