How a sperm enters an egg?
If semen gets in your vagina, sperm cells can swim up through the cervix. The sperm and uterus work together to move the sperm towards the fallopian tubes. If an egg is moving through your fallopian tubes at the same time, the sperm and egg can join together.

Cervical mucus filters out sperm with poor morphology and motility and as such only a minority of ejaculated sperm actually enter the cervix.

Shown at a cellular level magnification, sperm struggle through many obstacles in the female reproductive tract to reach the egg. Then genetic material from the egg and a single sperm combines to form a new human being.
What happens to the sperm cell after fertilization?
Once the sperm cell fuses with the egg cell, it becomes one cell, known as the zygote. This zygote (fertilised cell) then divides just like any other cell going through mitosis. Comment on IsotonicFlaccidCell21’s post “No it is still normal mit…”
