  • Intro
  • There are millions of suitors because I'm such a catch. Only few will make it very far and most likely one definite winner. 
  • Vagina
  • We've all made it up the great climb! Now on the the cervix!
  • Cervix
  • The Queen of the Uterus is in need of a king and will have suitors compete to be her husband. They must test themselves in a journey to fertilize her. Many will die during the journey due to acid, white blood cells, and just plain getting lost along the way. Their journey starts at the Vagina.
  • Uterus
  • By Bridget Berestecky and Grace Smalley
  • 250 million suitors enter the vagina as the first step of their journey to the Egg Queen. But WAIT! They have to survive the deadly acid that's used against intruding pathogens. 99% of the suitors will die here in only 30 minutes.
  • Fallopian Tubes & Fertilization
  • There are 60 thousand suitors remaining. Since Queen Egg is ovulating, there is no mucus plugging the cervix. That mucus softens and becomes watery to help the suitors enter.  In the cervix, there are tens of thousands of tunnels, but only one is the correct way, where as many others lead to nowhere. Most of the suitors will get lost in these paths and eventually die.
  • Uterus & Implantation
  • Which way should we go?
  • Only 3,000 suitors are remaining. Muscular contractions will help the suitors into the correct fallopian tube. BUT WAIT! Leukocyte monsters swarm them and attack many of the suitors, killing them instantly. Any sperm who survive these monsters must find their way to the fallopian tube. And that would be very few, since the suitors have to fit the Queen Egg's swimming standards to be allowed through.
  • Fellow men! Watch out for the Leukocytes! They are out to kill us!
  • The fallopian tubes are like heaven for the suitors. Servants treat them with glorious food and nutrients. Very few are still alive, only 10-30.  They will stay alive for several hours, or even days waiting for the Queen to appear.
  • This is heaven!
  • The remaining suitors are racing to Queen Egg. She releases chemicals in order for them to find her faster. Once Queen Egg is released from the ovary, she only lives for 24 hours. The suitors shed layers of protein so they can swim faster, because they only live for a few hours.
  •  When a lucky suitor finds Queen Egg, there is a bag of enzymes on it's head that explodes so it can enter the outer layer of the egg. Once the suitor is inside, his 23 chromosomes pair up with Queen Egg's. This process is called meiosis. The zygote travels back to the uterus as cells begin dividing. 4 days later, the group of cells is called a blastocyst. And 5 days later, the embryo implants itself in the wall of  the uterus.
  • It's a boy! Since the suitor was carrying a Y chromosome. We have a new heir to the throne!
