Mammalian Testes: Structure and Functionone formation from its precursor, cholesterol, is termed steroidogenesis. In this chapter, we will discuss how the structure and form of the testis contributes to the processes of spermatogenesis and steroidogenesis.

The Sperm Acrosome: Formation and Contentsneeded to transform an ordinary looking round spermatid into a hydrodynamically shaped spermatozoon with a fully developed acrosome varies from species to species and ranges from six to eight steps in man to 19 steps in rats and rabbits.

Testicular and Epididymal Maturation of Mammalian Spermatozoaed in developing spermatids and maturing spermatozoa. Thus, spermatozoa present in the testis and proximal epididymis are immotile and immature (infertile), while spermatozoa that reach the distal epididymis are motile and mature (fertile). In this context, the maturation of spermatozoa is defined a

Present knowledge on the role of different factors mediating development of male accessory glands is based on key experiments performed by several investigators (1–5). In 1940, Jost demonstrated a ro

It has also been thought to aid in the movement of embryo in the oviduct, and to ensure proper embryonic development as well as to prevent embryo fusion in the oviduct.
