For years, we’ve heard it told like a high-stakes race — millions of sperm, racing through the reproductive system like Olympic swimmers, all in a desperate dash to be the first to reach the egg. The fittest wins. The prize? Fertilization. Cue the heroic soundtrack. But that tale? It’s mostly myth, deeply rooted in a male-centric view of reproduction. Thanks to a 2020 study, we now know the egg isn't a passive prize at the finish line — it’s a powerful decision-maker in its own right. Turns out, the egg and sperm communicate. The egg releases chemoattractants — specific chemical signals — that draw in preferred sperm. And for the others? She slows them down with a repelling signal. Cervical mucus, particularly L-mucus, filters out weak or low-quality sperm before they even get a chance to swim. Bye, boy. As researcher Fitzpatrick put it:
"Follicular fluid from one female was better at attracting sperm from one male, while follicular fluid from another female was better at attracting sperm from a different male…"
Translation? It’s about compatibility. It’s her body, her choice — down to a molecular level. And once she’s made that choice and one lucky sperm starts penetrating the egg, she shuts it all down. The egg releases a chemical that causes every other sperm’s head to literally pop off. Yes — mass decapitation. No second chances. No backup winners. No maybes. Just the one she chose. Oh, and let’s not forget the poetic ending: Sperm? Smallest cell in the human body. Egg? Largest. She’s been running the show all along. It’s about time we told the story right.

It’s a conversation — and she gets the final word. 💪🧠💫
