If a human egg (from the female) and a human sperm (from the male) join together, then the egg is fertilised by the sperm and a human embryo is created. This human embryo grows over 9 months into a baby.

The result of fertilization of a human embryo is the formation of a zygote, which is a single cell that contains genetic material from both the sperm and the egg. This zygote will undergo cell division and development to eventually form a fetus.
The name given to the human organism two to eight weeks after fertilization is an embryo.
The formation of seeds is a result of the fertilization of eggs within the embryo sac. After pollination occurs and sperm cells from the pollen reach the egg cell in the embryo sac, fertilization takes place resulting in the development of a seed.
After fertilization, a human embryo implants into the endometrium of the uterus. The endometrium is the inner lining of the uterus where the embryo will embed and establish a blood supply in order to receive nutrients and oxygen for development. This process is known as implantation and is essential for the continuation of pregnancy.
At the time of implantation, a human embryo is called a blastocyst. This stage occurs about 5-7 days after fertilization and marks the implantation of the embryo into the uterus lining.
