What is the journey of sperm cells from ejaculation to conception?
The sperm leave the man’s penis by ejaculation and are deposited in the vagina high up near the cervix (the opening to the womb). The sperm immediately begin swimming and some will find their way into the cervix. The sperm then begin their long journey towards the egg. Leaving the cervix they enter the womb.
How does sperm travel to the egg?

What are the 4 steps of conception?
The stages of fertilization can be divided into four processes: 1) sperm preparation, 2) sperm-egg recognition and binding, 3) sperm-egg fusion and 4) fusion of sperm and egg pronuclei and activation of the zygote.
