Meet Egg. Egg lives with her friends in their safe haven, Ovary Village. Inside Ovary Village, life is constant and unchanging. But every month, one of Egg’s friends is selected to go on a journey. Egg eagerly awaits her turn to go on that journey.

One day, Egg hears someone calling her name. It’s Follicle. Follicle tells Egg, “Egg, your time has come. Are you ready to begin your journey?”
“Yes! Goodbye friends!” Egg says excitedly.

Egg joins Follicle, unsure of exactly where this journey will lead.
Egg realizes that she has never met Follicle and wonders how Follicle knows what to do.
“Follicle, how do you know where we are going?”

Follicle says, “We are guided by the all-knowing Brain. She gives us Follicle Stimulating Hormone, also known as FSH, which we use as food and helps us grow. In return, I give Brain Estrogen, which she uses to help the entire body.”
“Follicle, where exactly are we going?” Egg inquires.
“This is LH Mountain,” Follicle responds.

“Why are we going up LH Mountain?” Egg asks.
“LH stands for Luteinizing Hormone. LH Mountain helps us reach the next big step in your journey,” Follicle explains.

As they continue up the mountain, Egg starts to feel hungry. Follicle suggests, “Let’s take a quick snack break.” Egg and Follicle munch on some of the FSH from Brain, realizing they have been getting reasonably larger. Elsewhere, Brain is sorting Estrogen. “Some estrogen to the heart, some to the bones, and some for me.”

After 13 days, Egg and Follicle reach the peak of LH mountain.

Follicle says, “I cannot go any farther than this. Egg, from here, you are on your own.”
Over the course of their journey, Egg has gained confidence that she can do whatever Follicle and Brain tell her. “I am ready. What do I need to do?” wonders Egg.

Follicle instructs, “Your journey will continue down LH Mountain and onto Fallopian Tube Road. Ultimately, you want to reach Uterus City.”

“Along the way, you will meet new friends named Sperm. There will be millions of them, so be careful. You will have 14 days to decide if you want to live with any of them in Uterus City permanently.”

Egg hesitates, “What if I don’t find one that I like?”
Follicle is unsure how to respond. “All I know is that I will only be able to help you from afar during the remainder of your journey. Goodbye, Egg. Be brave.” As she says this, Follicle begins to turn yellow.

Egg continues on her journey. She notices that the estrogen food that she and Follicle had given Brain is now being used as material to build a very comfortable-looking house inside of Uterus City. Little yellow workers scurry by, taking bricks to the house.

“Who are you?” Egg stops one of them.

“We are Progesterone Workers. Follicle sent us here to help you,” one of them explains. They place their bricks onto the house.

14 days pass. Egg reaches Uterus City.

Egg’s house is looking quite comfortable. Egg has not come across any of the Sperm that Follicle was mentioning.

Suddenly, Egg notices the yellow bricks in the house beginning to crumble.

“What’s happening?” Egg exclaims in a panic.

“Egg, this is what Follicle meant,” Brain explains. “After 14 days, it is time for one of your friends from back home in Ovary to go on her journey. But for that to happen, we must wash away your house and start afresh. Goodbye, Egg.”

Egg and her house wash away, and her adventurous spirit passed on to the next Egg, ready to begin a new journey through the cycle again.
