1. What does gamete fusion and zygote formation refer to in human reproduction?
2. What is the primary role of sperm maturation and transit in the process of fertilization?
3. How does oocyte maturation differ from sperm capacitation in the fertilization process?
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.
