fertilized

This made no sense. All the eggs are fertilized already.

这可说不通，因为所有的卵都已经受精了。

But why should a molecule found on fertilized eggs release such fury?

但是为什么受精卵上的分子可以造成如此的愤怒。

After allowing the virus to infect the eggs, the team fertilized them with normal cat sperm and injected them into the fallopian tubes of 22 female cats.

病毒感染卵细胞之后，小组用正常猫精子使卵细胞受精，并且把这些受精卵注入22只雌性猫的输卵管中。
