Gamete fusion — definition?
Fusion of sperm and ovocyte to form zygote.
Sperm maturation — key step?
Acquisition of motility and recognition molecules in the epididymis.
Oocyte activation — trigger?
Sperm entry causes calcium influx, resuming meiosis.
Fécondation — definition?
Fusion of sperm and ovocyte to form zygote.
Zygote — role?
First embryonic cell, resulting from fertilization.
Capacitation — process?
Biochemical changes enabling sperm to fertilize.
Acrosome reaction — purpose?
Release enzymes to penetrate zona pellucida.
Polyspermy — prevention?
Cortical reaction hardens zona pellucida.
Pronuclei — formation?
Male and female nuclei after fertilization.
Cleavage — definition?
Embryonic cell division without growth.
