噗，试管那么小怎么装得下孩子。是胚胎！通过促排，分别取出卵子和精子，在体外结合，然后人工培育，成为胚胎以后再植回母亲体内。

Come on, a test tube is so small that there's no way it can fit a child. It's an embryo. After being discharged, eggs and sperm are collected separately and joined together outside the body. Then it's manually cultivated. After it becomes an embryo, it is implanted inside the mother's body again.
