Study Notes
Human Fertilization
- Human fertilization occurs primarily in the ampulla of the fallopian tube.
- The union of a human egg and sperm results in the production of a fertilized egg called a zygote, initiating embryonic development.
- The process of fertilization involves a sperm fusing with an ovum.
Sequence of Fertilization
- The most common sequence of fertilization begins with ejaculation during copulation, followed by ovulation, and finishes with fertilization.
- Exceptions to this sequence include:
- Artificial insemination
- In vitro fertilization
- External ejaculation without copulation
- Copulation shortly after ovulation
Sperm-Egg Interaction
- Upon encountering the secondary oocyte, the acrosome of the sperm produces enzymes to burrow through the outer shell called the zona pellucida of the egg.
- The sperm plasma then fuses with the egg's plasma membrane, and their nuclei fuse.
- The fusion of nuclei triggers the sperm head to disconnect from its flagella.
