Amazing image of an egg being fertilized!!!!

Gamete interaction generally involves five steps:
1. Chemoattraction of s***m by soluble molecules secreted by the egg;
2. Exocytosis of the s***m acrosome vesicle and release of its enzymes;
3. S***m binding to the egg's extracellular matrix (yolk envelope or zona pellucida);
4. Passage of s***m through the extracellular matrix;
5. Fusion of gamete membranes.
