Fertilisation i.e. fusion of a sperm and an ovum, is the first step in the process of reproduction.
Is reproduction a life process?
The various life processes are nutrition, respiration, transportation, and excretion. Reproduction is not regarded as a life process because it is not required to sustain life .

How do reproduction occurs in humans?
Reproduction In Human Beings
Humans do sexually reproduce mammals and so they are viviparous. The male and female gametes fuse together to give rise to an embryo. The fertilisation of the gametes and the development of an embryo until the childbirth occurs within the female.
