Question

Where does fertilisation occur in humans?

Answer 1

Fertilization:

1. Fertilization takes occurs in the fallopian tubes, where the sperm cell and the egg cell unite and produce a zygote (diploid).
2. The zygote will proceed down the fallopian tube and into the uterine lining, which is known as implantation, and the zygote implantation is known as a blastocyst.
3. When sperm and ovum come into contact, a change in the ovum's membrane (zona pellucida) occurs, which prevents subsequent sperms from entering.
4. It's critical that only one sperm joins the ovum.
