Yes, sperm can wait in the fallopian tube for an egg. After ejaculation, sperm can reach the fallopian tubes within minutes. However, they can survive there for up to 5 days, waiting for an ovulated egg. This remarkable survival ability enhances the chances of fertilization, as the timing does not have to be exact. The egg, once released, is viable for about 24 hours. This window allows for the potential fertilization to occur if sperm are already present within the fallopian tube.
