Pregnancy isn’t just biology, it’s a full-blown sci-fi war epic! Tens of millions of sperm launch themselves into battle, only for nearly all of them to die in a fortress of acid, mucus, and immune cells. The survivors then face the ultimate boss fight: an egg that’s 10,000 times bigger and armed with enough mitochondria to power a city. If one makes it in, the embryo begins its next phase: invading tissue like a parasitic octopus, brainwashing the uterus with chemical love notes, and even growing a brand-new organ just for the occasion: the placenta. It’s brutal and so metal that it almost sounds unbelievable. And yet, against all odds, this epic struggle often ends in one of the most magical things imaginable: a new life. Check it out!
