Introduction

Human fertilisation is the joining of a human egg and sperm, which takes place in the fallopian tube's ampulla. A zygote cell, or fertilised egg, is created as a result of this union, beginning foetal development.

A sperm fuses with an ovum during the process of fertilisation. The most typical progression is ejaculation during copulation, then ovulation, and finally fertilisation.
