Capacitation is an important physiological pre-requisite before the sperm cell can acrosome
react and fertilize the oocyte. Recent reports from several laboratories have amply …

Sperm capacitation: background 2.1. Modification in concentration of intracellular calcium
and other ions during capacitation 2.2. Changes in membrane lipids and phospholipids …

Insulin-like growth factor I (IGF-I) has been identified in human seminal plasma. This study
was conducted to determine whether IGF-I is present in bovine seminal plasma, whether …

Objective To follow-up and expand discussion on the action mechanisms of antisperm
antibodies in human infertility, the etiology and control of antisperm antibody induction …

We used a cell-free system to study membrane fusion during sperm exocytosis (acrosome
reaction). Extracted bovine sperm plasma and outer acrosomal membranes were labeled …

Introduction 3. Phospholipase C 3.1. Phosphoinositide-specific PLC (PIC) 3.2.

Several studies have shown that dopamine and other catecholamines are present in oviduct
luminal fluid. We recently reported that dopamine type 2 receptors (DRD2) are present in a …

At the time of fertilization mammalian spermatozoa undergo a Ca2+‐dependent exocytotic
event, which is known as the acrosome reaction (AR). We describe here that EGF‐receptor …

The involvement of serine and threonine phosphorylation in human sperm capacitation was
investigated. Anti-phosphoserine monoclonal antibody (mAb) recognized six protein bands …
