Have you ever wondered why only one sperm is allowed to enter the egg during fertilization? This short animation explains the amazing “Zona Pellucida Lock System” — a natural protective mechanism that prevents more than one sperm from entering. Learn how enzymes, receptors, and electrical changes instantly react the moment the first sperm touches the egg. Perfect for students and anyone curious about human reproduction. ‎‎#Fertilization #Pregnancy #Sperm #EggCell #HumanBiology #FemaleReproductiv

So many of you were invested in the bald egg that I injected, well unfortunately that embryo didn’t develop. But here’s an example of one that did! Thank you to an old colleague who shared this time-lapse video of a beautiful blastocyst that developed from a zona-free egg that she injected. 📸 Credit to ART Reproductive Center Beverly Hills, US
