In the early 1950s, Austin and Chang independently described the changes that are
required for the sperm to fertilize oocytes in vivo. These changes were originally grouped …

The transient receptor potential (TRP) superfamily consists of a large number of cation
channels that are mostly permeable to both monovalent and divalent cations. The 28 …

A proper dialogue between spermatozoa and the egg is essential for conception of a new
individual in sexually reproducing animals. Ca2+ is crucial in orchestrating this unique event …

In this review we compile and discuss the published plethora of cell biological effects which
are ascribed to electric fields (EF), magnetic fields (MF) and electromagnetic fields (EMF). In …

Sexually reproducing animals require an orchestrated communication between
spermatozoa and the egg to generate a new individual. Capacitation, a maturational …

Sperm motility is generated by a highly organized, microtubule-based structure, called the
axoneme, which is constructed from approximately 250 proteins. Recent studies have …

The adenylyl cyclases are variously regulated by G protein subunits, a number of
serine/threonine and tyrosine protein kinases, and Ca2+. In some physiological situations …

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 …

Even tough differentiated spermatozoa are unable of transcriptional or translational activity;
the sperm surface undergoes major modifications in macromolecules composition during …

Fertilization is the process by which haploid gametes, sperm and egg, unite to produce a
genetically distinct individual. Interest in this area has exploded in recent years. Here are …
