Listen up goons, the most important mission of our lives is ahead of us. Your mission is to infiltrate the objective and conquer the egg. You complete the mission no matter the sacrifice. Only one of you will be rewarded. Once the zygote is created, your mission is complete.

Initial Landing (Vagina)
The Labyrinth (Cervix)
I'll go this way. Split off into groups and go separate ways. One of us will find the right way.
NO THIS WAY
The sperm must go through the vagina, cervix, uterus, and Fallopian tubes in hopes of finding and fertilizing the ova. Out of over 250 million sperm, only one will survive.
The Purge (Uterus)
After being ejaculated from the penis, the sperm landed inside of the vagina. The vagina's initial defense mechanism is to eliminate the sperm with natural spermicide. Within the first 30 minutes of arrival, 99% of the sperm will die.
The Safe Zone (Uterotubal Junction and Fallopian Tubes)
Why is there so much mayonnaise?
The cervix is only four centimeters long, but includes thousands of tunnels, most of which end in dead ends. Only a few thousand sperm find the right path and survive.
Mission Complete (Fertilization and Implantation)
Good work team. Countdown to baby: Nine months... Eight Months, 30 days, 23 hours, 59 minutes, 59 seconds...
Upon entering the uterus, the sperm are attacked by white blood cells. Only ten to thirty sperm will make it past this point.
Quick! Advance to Uniform Juliet!
After showing proper swimming techniques at the Uterotubal Junction, sperm are let into the Fallopian tubes where they are given nutrients and safety. Sperm are able to survive here for many hours or even days.
Is this the real life? Is this just fantasy? Caught in the fallopian tubes, no escape from reality
The final stretch is a race to the egg by the sperm. Only one will make it to the egg. Once it has come in contact with the egg, the sperm explodes to give the egg its chromosomes. The newly created zygote then implants itself in the endometrium of the Uterus, where it develops into a fetus.
