of a sperm head showing the perforatorium (p), acrosomal vesicle (a), and extraacrosomal tissue (e).
When the spermatozoa reach the matured oocyte, the cumulus cells and zona pellucida surrounding the eggs are dissolved by hydrolytic enzymes distributed in the acrosomal vesicle of spermatozoa (Kohno et al., 1998; Tulsiani et al., 1998; Yamagata et al., 1998).
Acrosome reaction in abalone sperm involves the exocytosis of the acrosomal vesicle and the polymerization of subacrosoreal materials, composed mainly of actin, to form the anterior spike called acrosomal process (Neill & Vacquier 2004).
A consistent feature in most marine bivalve sperm is an electron-dense region at the base of the acrosomal vesicle. Termed the basal ring in Mytilus (Niijima and Dan, 1965), it was later isolated by Brandriff et al., (1978) in oyster and shown to agglutinate eggs.
It was observed in early spermatids at Golgi phase, formation of acrosomal granule contained in the acrosomal vesicle, spheroidal nucleus with rugous reticulum around it, and Golgi apparatus made up of lamellae and vesicular structures.
Unreacted sea urchin sperm contain a membrane-bounded acrosomal vesicle at the apex, which sits atop a nuclear fossa (a depression in the nucleus--see below) containing a granular mass of unpolymerized globular actin (G-actin) surrounding the actomere.
