The eggs need to get fertilized to move on with the process. For the eggs to fertilize, sperm needs to get into the female. This sperm is delivered by a male when he ejaculates. Ejaculation enters the female body after the intercourse between the male and female.

Once the eggs get fertilized, implantation happens around six days after the fertilization. It then becomes an embryo that develops eventually in the womb with the help of the placenta. It is here that the baby forms into a fetus, and then with time, the pregnancy proceeds. After around nine months, the female gives birth to the baby.
